Tornado Quest Top Science Links For October 28 - November 4, 2023 #science #weather #climate #hurricane #health

Greetings everyone. Thanks for stopping by. With a few weeks left in the Atlantic and Pacific hurricane season I will continue with hurricane preparedness information that you’ll find helpful. There are other interesting reads this week, so let’s get started. There’s a joke in here somewhere. “China’s spy-hunting campaign has a new target: ‘Illegal’ weather stations.” In our warming planet,…

“You are a battery composed of ELECTRONS. Just as a battery needs to be RE-CHARGED, so do YOU. Hence = the lack of CONNECTION with MOTHER EARTH has in reality decreased you of electrons. This is not fake science, but real science.” 🤔

Monday Musings: The Ring of Fire

Not gonna lie, every time I think about the Pacific Ring of Fire, this song gets stuck in my head (and I love this song so play away).

The Pacific Ring of Fire is a ring of volcanoes around the Pacific Plate Subduction zones.

It is about 25,000 miles long (40,000km) and it contains somewhere between 750-915 active and dormant volcanoes. This is about 2/3 or the world's total volcanoes!

It is also where about 90% of the world's earthquakes occur as well. Speaking of which, if you didn't hear there was an earthquake that happened on December 5th just off the coast of northern California. The recording will be posted on my Patreon so go join and check it out!

Now, this ring of fire is a complex system. I remember being taught as a kid that the Pacific Plate is subducting below like four different plates but that just isn't right. It's actually several plates interacting with each other. Let's zoom in.

We usually only hear about the large plates but there are tons of smaller ones around the globe. For instance, all the ones in this map. The red is the Philippine Plate which is subducting beneath the Eurasian Plate. As you can sea, the Pacific Plate is further out. Not subducting.

The Pacific Plate is subducting under parts of North America, but so is the smaller, older Juan de Fuca and Cocos Plates.

The Nazca Plate is being subducted along the west coast of South America as well as part of the Antarctic Plate. Just for funsies, the map below shows how much has been subducted and what the depth is.

The Ring of Fire has existed for a little over 35 million years. That means subduction of these plates began in the Late Eocene Epoch.

The largest volcanic eruptions in human history occurred in the Ring of Fire. We will start with the 1902 Santa Maria eruption in Guatamala. The volcano is estimated to have started erupting about 103,000 years ago during the Pleistocene Epoch. However, by 102 it was considered dormant. The 1902 eruption had a VEI (Volcanic Explosive Index) of 6 (the highest being a 7) which makes it "colossal".

Mt. Pinatubo activity began about 1.1 million years ago (known as Ancestral Pinatubo). The modern Pinatubo began erupting about 79,000 BC. It's eruption in 1991 is the most famous though. It was the second largest eruption in the 20th century but a lot more devastating. It was also rated a 6 on the VEI and it ejected about 10 cubic km worth of material (10 times larger than the Mt St Helen eruption a decade earlier).

Before and after shot of the river valley near Pinatubo.

Lake Pinatubo now fills the crater left behind by the eruption.

One of the most famous is the 1883 eruption of Krakatoa. It's eruption was so violent that it was heard in Perth Australia nearly 2,000 miles away.

It caused a massive pressure wave that was recorded on barographs around the world (in some cases, the wave was recorded 7 times!). It created devastating tsunamis and killed at least 36,000 people. The eruption lasted from May until October peaking in August when nearly the entire island collapsed into a caldera. Ash fell over approximately 1500 squares miles and the eruption caused a volcanic winter. This one is also categorized as a 6 VEI.

The largest eruption in the Holocene was that of Mt. Tambora in 1815. The volcano had been dormant for centuries caused by gradual cooling of hydrous magma in its closed magma chamber. At depths of abot 5,000-15,000 ft, the exsolution began to form causing an over-pressurization in the chamber (about 58,000-73,000 psi) with temps ranging between 700-850 degrees Celsius (1,290-1,560 degrees F). It is thought that the explosions from the initial eruption could be heard clear over in Thailand over 2,000 miles away.

Pyroclastic flows wiped out the village of Tambora and 13 ft tsunamis hit many Indonesian islands. The explosion had an estimated VEI of 7 with an estimated 10 cubic miles (41 cubic km) of ejecta weighing 10 billion tonnes. The caldera left behind is about3-4.5 miles across and nearly 2300ft (700m) deep. The eruption released the amount of energy equivalent to 33 gigatons of TNT. This was such a large eruption that it caused the Year Without A Summer in the northern hemisphere. The dramatic cooling directly and indirectly killed 90,000 people. Way to go Tambora.

The largest earthquakes on Earth as well including the Sumatra earthquake in 2004 whose 100ft high tsunami killed over 200,000 people in 14 countries the day after Christmas.

There is also the Greta Chilean Earthquake in 1960 estimated at a magnitude 9.4 on the moment magnitude scale. An 82ft tsunami battered the Chilean shores and effected Hawaii, Japan, the Philippines, New Zealand, Australia and the Aleutian Islands.

All in all, the Ring of Fire is a deadly mix in geologic terms and insanely fascinating as it gives a spectacular look into the inner workings of our planet.

Tune in tomorrow for some volcanic trivia! Fossilize you later!

Perihelion and Aphelion: Earth's Dance with the Sun

Perihelion and Aphelion, the two significant points in Earth's annual journey around the Sun, mark the times when our planet's orbit is closest to and farthest from the Sun, respectively. These celestial events play a crucial role in shaping our planet's climate, seasons, and overall astronomical dynamics, as Earth's orbit is not a perfect circle but rather an elliptical shape.

Hurricane Lee over the western Atlantic Greeting everyone. Thanks for stopping by. The major stories this past week have been Hurricane Lee, the first Atlantic hurricane to reach Category 5 status, the flooding on Lybia, and the earthquake in Morocco. As for the topical Atlantic, there are several more weeks left in the 2023 hurricane season. I will continue with hurricane preparedness…

Candace Owens: “I’m not a flat-earther. I’m not a round-earther. Actually, what I am is someone who has left the cult of science.” 👇

Personally, for me, it has been about being willing to forget everything I was taught and willing to relearn with an open mind.

People think I believe everything I post when in fact my Bio states; "it's a blog to make you think." I'm not pushing any be-LIE-fs on anyone nor am I trying to. Think for yourself and stop judging others. Don't condemn them for who they are, because in reality you don't know them at all by what they post. 🤔
