My partner, while we were in Mt Gambier the other week: so should we be worried about new sinkholes opening up around here?

Tourist information lady: no no, these are cenotes, they form over time, they don't just happen

Mt Gambier: bet

Sorry about the new holes @derinthescarletpescatarian

Scientists have discovered towering salt chimneys, called "white smokers," on the Dead Sea floor. These formations offer clues to geological processes and may help predict sinkholes.

Why are there suddenly huge sinkholes in Anatolia? | Focus on Europe

Sinkholes near residential areas have suddenly opened up in central Turkey because of groundwater runoffs. And they’re becoming deadly hazards for people and animals.

All about Cover-collapsed Sinkholes

Cover collapse sinkholes occur when the ground surface collapses into a subsurface void or cavity. This type of sinkhole is particularly dangerous because it can cause sudden and dramatic ground subsidence. You might not want to get swallowed by one!

How Cover collapsed sinkholes processes:

The bedrock below the surface erodes making space for the soil and rocks to sink making space under the solid cover of the crust. Because no solid ground is holding the crust, the weight of the cover/crust cause it to collapse because of lacking support, resulting in a sudden subsidence of the ground, a sinkhole.

Learning about sinkholes is pretty important because they can pop up unexpectedly and cause a lot of trouble. Imagine you’re walking down the street, and suddenly, the ground starts to cave in. That’s a sinkhole in action, and it can swallow up everything from roads to houses. Always be aware of your surrounding! :)

My friend just sent me the greatest home listing I think I have ever seen

I mean, check out this beutiful riverside home! Double garage! Upstairs access from the outside! Lets check out the inside

Open concept kitchen, nice, nice

Oh, the whole Floorplan seems to be open concept. Okay! That floor is a little odd, but not a deal breaker.

That bathroom could use an update

Need to change out that curtain

Okay, let's go take a look at the back yard!

Abstract

We study the interrelations between salt karst and landscape evolution at the Ze’elim and Hever alluvial fans, Dead Sea (DS), Israel, in an attempt to characterize the ongoing surface and subsurface processes and identify future trends. Using light detection and ranging, interferometric synthetic aperture radar, drone photography, time-lapse cameras, and direct measurements of floodwater levels, we document floodwater recharge through riverbed sinkholes, subsurface salt dissolution, groundwater flow, and brine discharge at shoreline sinkholes during the years 2011–2023. At the Ze’elim fan, most of the surface floodwater drains into streambed sinkholes and discharges at shoreline sinkholes, whereas at the Hever fan, only a small fraction of the floodwater drains into sinkholes, while the majority flows downstream to the DS. This difference is attributed to the low-gradient stream profiles in Ze’elim, which enable water accumulation and recharge in sinkholes and their surrounding depressions, in contrast with the higher-gradient Hever profiles, which yield high-energy floods capable of carrying coarse gravel that eventually fill the sinkholes. The rapid drainage of floodwater into sinkholes also involves slope failure due to pore-pressure drop and cohesion loss within hours after each drainage event. Surface subsidence lineaments detected by InSAR indicate the presence of subsurface dissolution channels between recharge and discharge sites in the two fans and in the nearby Lynch straits. Subsidence and streambed sinkholes occur in most other fans and streams that flow to the DS; however, with the exception of Ze’elim, all other streams show only minor or no recharge along their course. This is due to either the high-gradient profiles, the gravelly sediments, the limited floods, or the lack of conditions for sinkhole development in the other streambeds. Thus, understanding the factors that govern the flood-related karst formation is of great importance for predicting landscape evolution in the DS region and elsewhere and for sinkhole hazard assessment.

Such a stupid question I hope it makes sense. Where is the Earth going in sinkhole? Like HOW is there a gap between earth and earth idk I just

HA

I hit a pothole (a Michigan pothole so basically a sinkhole) today and my check engine light came on. I don’t have one of those computer plugins to reset the light and I knew it was just a sensor that got knocked so I was just like “well let’s see if this works” and on the way home I swerved and hit the pothole again and the check engine light turned off
