The Fantastic Four Movie Problem: A Pulp Peg in a Hero-Shaped Hole.

There's been a lot of attempts to make Fantastic Four movies, and none of them have really worked.

(I made the best one biggest. Fight me.)

I know why.

It's because the Fantastic Four, while being in the superhero genre, are not superheroes. They are adventurers.

They have more in common with these guys:

Than these guys:

And it all comes down to story structure, particularly in the origin episode.

Superheroes are by nature reactive. They respond to threats, protect people, and generally act as a blend of rescue worker and (usually) nonlethal sheriff. They are the heightened-reality version of the helpers of Mr. Rogers' philosophy. Doomsday shows up, you stop Doomsday. If there's no crime, you're not doing anything that day.

But the Fantastic Four, and particularly Reed, are adventurers. They go and find their trouble. There might be vague rumblings of something strange or unusual seismic activity or whatever to initiate the adventure, but Reed isn't waiting for the phone to ring so he can punch a bank robber, he's making plans for an expedition to Monster Island or he's built a doorway to the Negative Zone for the express purpose of exploring another universe.

The Fantastic Four go looking for interesting things and find trouble when they get there. The main exception to this is Doctor Doom, and the rush to make him the main villain in the first film is a rush past a glorious feast to go straight to the dessert.

It's like starting Holmes off face to face with Moriarty from day one, and it puts the Fantastic Four in the same do-gooder box as the rest.

It chops out their most unique aspect, their proactive nature, that all their personalities hinge on: It informs Reed's obsessive need to know and how it warps his priorities. It feeds Johnny's thrill-seeking and recklessness. Ben's mutation is the cost of that drive taken to the point of hubris and informs the spirit of the whole team. And Sue, who is the most traditionally superheroic in her outlook, has the codependent role of keeping her loved ones safe despite their self-destructive adventurism.

It's a long standing fandom joke that Reed is an asshole.

It's not unwarranted, but the whole team is a dysfunctional but still caring family, each with similar flaws. A thing that the adaptations often lose because they wind up being overly bicker-y to make up for the more static, reactive superhero format, and blaming Reed for them being freaks is easy pathos.

If they were treated as the pulp adventurers they are in spirit, you'd have a lot more chances for them to bond as each leg of the journey into the Savage Land runs into natural hazards and lesser foes on the way to the climax fight.

In short: Pulp it up.

Of particular concern are signals of massive earthquakes in the region’s geologic history. Many researchers have chased clues of the last “big one”: an 8.7-magnitude earthquake in 1700. They’ve pieced together the event’s history using centuries-old records of tsunamis, Native American oral histories, physical evidence in ghost forests drowned by saltwater and limited maps of the fault. 

But no one had mapped the fault structure comprehensively — until now. A study published Friday in the journal Science Advances describes data gathered during a 41-day research voyage in which a vessel trailed a miles-long cable along the fault to listen to the seafloor and piece together an image.

The team completed a detailed map of more than 550 miles of the subduction zone, down to the Oregon-California border.

Their work will give modelers a sharper view of the possible impacts of a megathrust earthquake there — the term for a quake that occurs in a subduction zone, where one tectonic plate is thrust under another. It will also provide planners a closer, localized look at risks to communities along the Pacific Northwest coast and could help redefine earthquake building standards. 

“It’s like having coke-bottle glasses on and then you remove the glasses and you have the right prescription,” said Suzanne Carbotte, a lead author of the paper and a marine geophysicist and research professor at Columbia University’s Lamont-Doherty Earth Observatory. “We had a very fuzzy low-resolution view before.”

The scientists found that the subduction zone is much more complex than they previously understood: It is divided into four segments that the researchers believe could rupture independently of one another or together all at once. The segments have different types of rock and varying seismic characteristics — meaning some could be more dangerous than others. 

Earthquake and tsunami modelers are beginning to assess how the new data affects earthquake scenarios for the Pacific Northwest. 

Kelin Wang, a research scientist at the Geological Survey of Canada who was not involved in the study, said his team, which focuses on earthquake hazard and tsunami risk, is already using the data to inform projections. 

“The accuracy and this resolution is truly unprecedented. And it’s an amazing data set,” said Wang, who is also an adjunct professor at the University of Victoria in British Columbia. “It just allows us to do a better job to assess the risk and have information for the building codes and zoning.” 

Harold Tobin, a co-author of the paper and the director of the Pacific Northwest Seismic Network, said that although the data will help fine-tune projections, it doesn’t change a tough-to-swallow reality of living in the Pacific Northwest.

“We have the potential for earthquakes and tsunamis as large as the biggest ones we’ve experienced on the planet,” said Tobin, who is also a University of Washington professor. “Cascadia seems capable of generating a magnitude 9 or a little smaller or a little bigger.” 

A quake that powerful could cause shaking that lasts about five minutes and generate tsunami waves up to 80 feet tall. It would damage well over half a million buildings, according to emergency planning documents. 

Neither Oregon nor Washington is sufficiently prepared.

To map the subduction zone, researchers at sea performed active source seismic imaging, a technique that sends sound to the ocean floor and then processes the echoes that return. The method is often used for oil and gas exploration. 

They towed a 9-plus-mile-long cable, called a streamer, behind the boat, which used 1,200 hydrophones to capture returning echoes. 

“That gives us a picture of what the subsurface looks like,” Carbotte said.

Trained marine mammal observers alerted the crew to any sign of whales or other animals; the sound generated with this kind of technology can be disruptive and harm marine creatures. Carbotte said the new research makes it more clear that the entire Cascadia fault might not rupture at once.

“It requires an 8.7 to get a tsunami all the way to Japan,” Tobin said.

"The next earthquake that happens at Cascadia could be rupturing just one of these segments or it could be rupturing the whole margin,” Carbotte said, adding that several individual segments are thought to be capable of producing at least magnitude-8 earthquakes. 

Over the past century, scientists have only observed five magnitude-9.0 or higher earthquakes — all megathrust temblors like the one predicted for the Cascadia Subduction Zone. 

Scientists pieced together an understanding of the last such Cascadia quake, in 1700, in part via Japanese records of an unusual orphan tsunami that was not preceded by shaking there. 

The people who recorded the incident in Japan couldn’t have known that the ground had shaken an ocean away, in the present-day United States. 

Today, the Cascadia Subduction Zone remains eerily quiet. In other subduction zones, scientists often observe small earthquakes frequently, which makes the area easier to map, according to Carbotte. That’s not the case here. 

Scientists have a handful of theories about why: Wang said the zone may be becoming quieter as the fault accumulates stress. And now, we’re probably nearing due. 

.“The recurrent interval for this subduction zone for big events is on the order of 500 years,” Wang said. “It’s hard to know exactly when it will happen, but certainly if you compare this to other subduction zones, it is quite late.”

By studying the travel times and velocities of these waves, geotechnical engineers can obtain accurate data about the soil and rock layers. This information is essential for projects requiring a detailed understanding of underground properties, such as structural stability, material density, and elasticity.

How Crosshole Seismic Surveys Work Borehole Drilling First, two or more boreholes are drilled at specified locations within the survey area. The distance between these boreholes is critical to ensure the accuracy of the seismic data collected.

Seismic Source A seismic source, typically a small explosive charge or hammer, generates controlled seismic waves within one borehole.

Receivers in Adjacent Boreholes Seismic receivers are placed in adjacent boreholes to detect the waves as they travel through the subsurface material. These receivers record the waves, capturing details of their speed and attenuation.

Data Collection and Analysis The travel time and velocity of the seismic waves are analyzed to create a profile of subsurface properties, such as density, shear wave velocity, and compressional wave velocity. This data is then interpreted to give a comprehensive understanding of the subsurface structure and material composition.

Key Benefits of Crosshole Seismic Surveys High Resolution and Accuracy Crosshole seismic surveys offer high-resolution data and accuracy unmatched by surface seismic methods. The close proximity of boreholes enables the precise measurement of seismic velocities, which is essential for geotechnical projects requiring detailed information about subsurface materials.

Marapi volcano in Indonesia erupts, spewing ash and hot clouds

One of Indonesia’s most active volcanoes erupted at least three times on Sunday, spewing thick columns of ash and showering villages with debris, but no casualties were reported.

Marapi volcano, located in Agam district of West Sumatra province, is known for its sudden eruptions, which are difficult to predict because they are not caused by the underlying magma movement that triggers tremors recorded by seismic monitors.

According to Ahmad Rifandi, an official at the Indonesian Centre for Volcanology and Geological Hazards Mitigation at the Marapi monitoring post, clouds of hot ash spread for miles, covering nearby villages and towns in thick volcanic debris. Pillars of ash reached heights of 2,000 metres (6,560 feet).

Rifandi said the nearly 2,900-metre (9,480-foot) volcano has been on the second of four alert levels since January, prohibiting climbers and villagers from staying within 3 kilometres (1.8 miles) of the crater mouth because of a possible lava eruption.

Marapi erupted in December 2023, killing 24 climbers and injuring several others who were caught in a sudden eruption over the weekend. Two climbing routes on the mountain have since been closed.

Indonesia is in a seismically dangerous zone, the Pacific Volcanic Ring of Fire, home to about 130 active volcanoes.

Understanding Seismographs and Seismometers: A Look at Their Importance and the Role of Seismograph Providers in Delhi

Seismographs and seismometers are essential tools used to measure seismic activity in the Earth's crust. These devices are instrumental in detecting and recording vibrations caused by natural events like earthquakes and man-made activities such as explosions or construction work. For countries like India, where earthquake-prone zones exist, having access to reliable seismographs is crucial for monitoring and mitigating seismic risks. In this blog, we will explore the importance of these instruments, their applications, and the role of a seismograph provider in Delhi in making this technology accessible.

What is a Seismograph?

A seismograph is a device that records the vibrations or seismic waves produced by events like earthquakes. It consists of three main components: a mass, a frame, and a recording system. When an earthquake occurs, the seismic waves cause the ground to shake. The mass in the seismograph remains stationary due to inertia, while the frame moves with the ground. This movement is recorded as a graph, called a seismogram, which shows the intensity and duration of the seismic event.

Seismographs can detect even the smallest tremors, helping scientists and researchers understand the behavior of the Earth’s crust. By analyzing the data collected by seismographs, experts can determine the location, magnitude, and depth of an earthquake. This information is vital for predicting future seismic activity and for designing buildings and infrastructure that can withstand earthquakes.

Seismometers and How They Work

A seismometer is the sensitive component within the seismograph that measures ground motion. It detects the vibrations caused by seismic waves and converts them into electrical signals, which are then processed and displayed on the seismogram. Modern seismometers are highly sensitive and can detect minute ground movements that are not noticeable to humans.

Seismometers come in various types, including short-period seismometers, which are ideal for detecting local earthquakes, and broadband seismometers, which can detect a wide range of seismic waves over long distances. The choice of seismometer depends on the specific requirements of the seismic survey, such as the type of ground being studied or the expected magnitude of the seismic activity.

Importance of Seismographs and Seismometers

Seismographs and seismometers play a crucial role in understanding the Earth’s seismic behavior. Their importance can be highlighted in several key areas:

Earthquake Monitoring: In regions prone to earthquakes, such as India, seismographs help in monitoring seismic activity. By continuously recording ground vibrations, seismographs provide early warning signals that can be used to alert people and authorities about impending earthquakes, potentially saving lives.

Construction and Engineering: When designing buildings, bridges, or other structures in earthquake-prone areas, it is vital to understand the seismic risks. Seismographs and seismometers help engineers and architects assess the ground conditions and build structures that are earthquake-resistant.

Scientific Research: Seismographs are essential tools for studying the internal structure of the Earth. By analyzing seismic waves, scientists can gather information about the Earth’s layers, tectonic plate movements, and volcanic activity.

Environmental Monitoring: In addition to detecting earthquakes, seismographs can also be used to monitor other environmental phenomena, such as landslides, volcanic eruptions, and even underground nuclear tests.

Public Safety and Disaster Management: Seismographs provide valuable data that can be used by government agencies and disaster management teams to prepare for and respond to earthquakes. This data is also useful for creating hazard maps, which identify areas at risk of seismic activity and guide urban planning and development.

Seismograph Providers in Delhi

In India, the growing demand for seismic monitoring equipment has led to the rise of several reliable providers. A seismograph provider in Delhi plays a crucial role in ensuring that businesses, government agencies, and research institutions have access to high-quality seismic monitoring tools. Whether for scientific research, construction projects, or earthquake monitoring, a trusted seismograph provider in Delhi supplies equipment that meets the specific needs of each client.

Delhi, located in a region that experiences seismic activity, has seen an increase in the use of seismographs and seismometers in recent years. As the city continues to expand, ensuring that infrastructure is resilient to earthquakes is of paramount importance. By providing state-of-the-art seismic monitoring equipment, a seismograph provider in Delhi helps organizations and authorities stay prepared for any seismic events.

Artificial Intelligence in Disaster Management: How Artificial Intelligence is Aiding Crisis Response

Artificial Intelligence in Disaster Management: How Artificial Intelligence is Aiding Crisis Response Disasters, both natural and man-made, have been a challenge for humanity for centuries. Whether it’s a hurricane, earthquake, wildfire, or flood, the impact of these events can be devastating, resulting in loss of life, destruction of infrastructure, and economic damage. In recent years, artificial intelligence (AI) has emerged as a game-changing tool in disaster management, providing valuable insights and improving response times. Through predictive analytics, real-time data processing, and enhanced decision-making, AI is aiding crisis response efforts in unprecedented ways. This article explores how AI is transforming disaster management, from early warning systems to optimizing relief efforts, and how its integration into crisis response is making communities more resilient.

Predictive Analytics for Early Warning Systems One of the most significant contributions of artificial intelligence to disaster management is the enhancement of early warning systems. AI algorithms can analyze vast amounts of data from weather patterns, geological activities, and historical records to predict the likelihood of disasters such as hurricanes, floods, and earthquakes. These predictive models enable authorities to issue timely warnings, allowing people to evacuate or prepare for an impending disaster. For instance, machine learning models can analyze satellite data and weather information to predict the path and intensity of hurricanes. Similarly, AI can analyze seismic activity to estimate the likelihood of an earthquake. This capability significantly improves the accuracy of early warnings, giving people more time to respond and reducing the potential loss of life. In the case of wildfires, AI is being used to detect anomalies in temperature, wind patterns, and humidity levels, allowing fire departments to anticipate where a fire might spread next. This predictive approach is vital in areas prone to large-scale wildfires, as it enables firefighters to contain the blaze before it grows out of control.

Real-Time Data Processing During Disasters In the midst of a disaster, real-time information is crucial for effective crisis management. AI systems excel at processing and analyzing data in real time, providing authorities with up-to-the-minute information on the disaster’s progression and its impact on affected areas. Drones equipped with AI technology, for example, can be deployed to capture aerial footage of disaster zones. These drones can then use AI to analyze the footage, identify damaged areas, and locate survivors who may need immediate assistance. AI-powered tools like these help emergency responders prioritize rescue efforts by identifying areas where help is most urgently needed. For instance, during the aftermath of a flood, AI systems can process data from sensors, satellite images, and social media posts to pinpoint locations with the highest concentration of people in need of rescue. This enables first responders to allocate resources more efficiently and reach those who are trapped or isolated by floodwaters. Additionally, AI can assist in assessing the structural integrity of buildings after earthquakes or other catastrophic events. By analyzing real-time sensor data, AI systems can identify buildings that are at risk of collapse, ensuring that rescue teams avoid hazardous areas.

Optimizing Relief Efforts and Resource Allocation Managing resources efficiently is one of the most challenging aspects of disaster response. AI is playing an increasingly important role in optimizing relief efforts by helping authorities allocate resources like food, water, medical supplies, and personnel more effectively. Through advanced analytics, AI can predict which areas are likely to be hit hardest and require the most aid, allowing relief organizations to pre-position supplies and personnel. In the aftermath of a disaster, AI can also analyze logistics data to streamline the delivery of aid. For example, AI systems can optimize transportation routes by taking into account real-time information on road conditions, weather patterns, and infrastructure damage. This ensures that aid reaches affected areas as quickly as possible, minimizing delays and reducing the suffering of disaster victims. Furthermore, AI can be used to predict the long-term needs of disaster-stricken areas. By analyzing historical data and current conditions, AI can forecast the future needs of affected communities, such as medical supplies, housing, or sanitation facilities. This proactive approach enables aid organizations to plan for the recovery phase of disaster management more effectively.

Enhancing Communication During Crisis Response During a disaster, clear and timely communication is essential for coordinating rescue and relief efforts. AI-powered chatbots and virtual assistants are increasingly being used to improve communication during crises. These AI systems can interact with affected populations through messaging apps, providing them with real-time information on evacuation routes, emergency shelters, and safety guidelines. AI chatbots can also be used to gather information from survivors, helping authorities assess the extent of the damage and prioritize rescue efforts. For instance, during an earthquake, a chatbot might ask survivors about their location, the condition of their building, and whether they need medical assistance. This information is then relayed to emergency responders, ensuring that help arrives as quickly as possible. Conclusion Artificial intelligence is rapidly becoming an indispensable tool in disaster management. From improving early warning systems to optimizing resource allocation and enhancing communication during crises, AI is making a significant impact on how we respond to disasters. As AI technology continues to evolve, it will undoubtedly play an even more prominent role in saving lives and reducing the impact of disasters in the future. For professionals looking to leverage AI in disaster management, pursuing an artificial intelligence course is an excellent way to gain the skills and knowledge necessary to apply AI effectively in crisis response. With AI’s growing importance in disaster preparedness and recovery, understanding how to harness this technology can make a critical difference in protecting communities and ensuring a faster, more efficient response to emergencies.

Distributed Acoustic Sensing: The Future of Downhole Monitoring

Distributed Acoustic Sensing is an optical fiber sensing technique that uses fiber optic cables to detect and record acoustic and seismic signals along extended distances. Standard DAS arrays can continuously monitor signals over distances of 10-100 km with resolutions as fine as 1 meter. Specialty this systems can monitor over distances greater than 100 km.

How Does it Work?

Distributed Acoustic Sensing works by detecting acoustic or seismic signals that interact with the fiber optic cable. Standard telecommunications optical fibers are used, with no special components required within the fiber itself. Laser pulses are sent down the fiber and any signal that mechanically perturbs the fiber will cause some of the backscattered light to change wavelength via the Brillouin effect. This change is measured and provides information about the location and nature of the acoustic signal. By timing the return signal, the system can accurately locate acoustic events to within centimeters over the entire length of the fiber.

Applications for Downhole Monitoring

One of the most promising applications for Distributed Acoustic Sensing (DAS) is in downhole monitoring during oil and gas operations. Standard techniques like tubing-deployed monitoring tools provide point measurements but are unable to continuously monitor zones between sensor locations. It offers the potential to monitor acoustic signals along the entire length of production or injection wells. This opens up possibilities like:

- Flow profiling to detect zones of higher or lower flow along horizontal wellbores. Pinpointing fluid movement across fractures or between reservoir layers.

- Completion diagnostics to locate failed zones, casing leaks or other problems without pulling tools in and out of the well. Real-time monitoring avoids unnecessary workovers.

- Hydraulic fracturing monitoring to observe fracture propagation in unprecedented detail. It can detect the exact location and timing of perforation shots from multi-stage fracs to optimize treatment.

- Production monitoring to detect downhole fluid problems like sand ingress or water breakthrough earlier. Real-time zonal isolation monitoring avoids premature well shut-ins or abandonment.

Challenges for Downhole Deployment

While it shows tremendous promise for downhole monitoring applications, several technical challenges must still be addressed for reliable long-term deployment down wellbores:

- Temperature effects - Standard telecom fibers exhibit significant signal attenuation above around 80°C which limits applications to shallower wells or those with significant cooling. Ruggedized high-temperature fibers are being developed and tested.

- Fiber protection - Downhole fibers must withstand abrasive fluids, sand production, production tubing movement and other hazards. Robust protective coatings and housings are an active area of research to provide sufficient buffering.

- Deployment reliability - Repeated deployment of Distributed Acoustic Sensing cables downhole without damage requires further refinement of deployment tools and techniques. Improved reliability avoids unnecessary operational costs.

- Power supply – Downhole sensors require reliable long-term power, usually supplied topside via the fiber optic cable itself. High temperatures and rugged deployment impact power delivery abilities.

Overcoming these challenges is an area of active industry R&D with progress continually being made. As reliability improves, it promises to transform downhole monitoring capabilities.

Permanent Reservoir Monitoring Applications

In addition to deployments during discrete operations like hydraulic fracturing treatments, permanent reservoir monitoring (PRM) use cases provide some of the most exciting potential applications for Distributed Acoustic Sensing technology:

- Long-term zonal isolation - Continuously monitor for fluid migration or casing issues for early remediation to avoid premature reservoir compartmentalization.

- Water/gas coning detection - Detect upward fluid fronts earlier to optimize production strategies before detrimental water/gas breakthrough.

- Compartmentalized reservoir management - Optimize production across disparate zones within the same reservoir by continually profiling inter-zonal flow behaviors.

- 4D seismic correlation - Directly correlating time-lapse 4D seismic surveys with downhole fluid fronts encountered by DAS arrays to rapidly refine subsurface models.

- Borehole stability monitoring - Detect microseismicity, casing strains or fractures for zonal integrity assurance over decades-long field lifetimes. Avoid costly workovers.

The ability to continually monitor entire wellbores for decades enables unprecedented reservoir insight to maximize recovery. As technical issues are solved, PRM using it will drive major efficiency gains across mature fields globally.

Distributed acoustic sensing using fiber optic cables represents a disruptive new monitoring paradigm. Moving away from discrete downhole sensors towards continuum sensing unlocks capabilities never before possible. With continued progress,it  will profoundly impact how subsurface operations are planned, executed and optimized. Permanent reservoir and long-term zonal isolation monitoring promise to drive step-changes in efficient, cost-effective oilfield management. It is truly the future of downhole monitoring and reservoir insight.
