It's a region - that whole crescent of mountains from the Taurus range through the Caucasus through Iran - that's prone to bad earthquakes, and has buildings that are either old, or built to very low construction standards.  Very deadly earthquakes like this happen every decade or two - Tabas in 1978, Rasht in 2000, Baravat in 2008, Izmit 1999.

 

This isn't anything unusual, sadly.

 

I also heard an interview with a Turkish geologic Professor this morning.

He said that Turkey changed its building codes after their 1999 Quake, and they have mandatory insurance for newer construction.  He was pretty dismayed, however, by what he saw -- intimating that these buildings shouldn't have collapsed the way they did (though he wasn't clearly talking about post-1999 construction).  He hinted strongly at holding an opinion that the new, post-1999 codes aren't being followed. Disappointing, if true, but not really surprising (his word was "embarrassing").

Spot on! Not surprising at all

 

Could that be an indictment of a lot of the Middle East? 

 

A case of using "Inshallah" to get around the codes and turn a buck, willingly or just ignorantly? Sometimes religion gets in the way. Heck, a lot of times, it gets way in the way of science.

 

One of the guys I work with volunteered to get deployed to the Middle East... Iraq, Afghanistan... He's been there as a QA/inspector on construction projects.  The local contractors notoriously skirt the codes/regulations. Soldiers were getting electrocuted when they took a shower... Grounding the hot water tanks seemed to be a practice they cut corners with. /smdh...

This earthquake badly devastated the region im from in the south of Italy and the mafia basically stole most of the rebuilding money.  

 

Not sure how the buildings will hold when it happens again unfortunately.

Cascadia fault line could be ready to shift. And that would be VERY bad

Oceanographers working off the coast of Oregon have made a potentially alarming discovery. They’ve found a vent in the ocean floor that is pushing out warm water. On the surface, that may not sound all that remarkable or dangerous, but the chemical composition of the water suggests that it’s coming up from a deep vent and it’s located on top of the Cascadia Subduction Zone. We’ve covered this topic here in the past, but if you’re not familiar with the CSZ there are some good documentaries online where you can learn the details. The short version of the story is that the CSZ “slips” on a regular basis every 300 to 400 years. When it does, it causes an earthquake of at least magnitude 8 or 9. And very shortly after that, a tsunami that looks like nothing seen in our lifetimes comes ashore from southern Canada to northern California destroying everything in its path. This leaking vent in the seafloor could be an early indicator that the next slip is on the way.
 

The last CSZ quake happened in January of 1700. The Native Americans still talked of it in their oral traditions and told the first European settlers arriving in the region about it. The death toll was horrific, though there was very little in the way of construction to be destroyed in the region at the time. It’s a given that another one is coming and we’re already in the window of time when it would typically happen.

 

The question is, what are we supposed to do with this information? We’ve known this is coming for quite a while now and back in 2016 officials were conducting emergency evacuation drills in Oregon to try to prepare for it. But there’s only so much you can do, realistically.

Stories are greatly overstating the presumed risk this vent represents.  The paper itself states nothing of the sort.

 

But that hypothetical tsunami?  Oregon coast has something like six minutes' warning time.  Not even worth trying to evacuate if you're on the coast - try to run, you'll just die tired.

Or you can be swept out to sea trying to take pictures. (NorCal but close to the Oregon border). 2015
 

"The Coast Guard is searching for a man swept out to sea in Northern California while taking pictures of tsunami waves.

Nearby, authorities in Brookings, Ore., say four people have survived after a tsunami surge swept them off a beach in Curry County and into the sea.

The five were on the beach Friday to watch the waves generated by a massive earthquake in Japan. The Curry County sheriff's department says two were able to get out of the water on their own, and two were rescued by law enforcement and fire officials."

Global warming causing the eruptions 

 

 

Quote

A study published in 2022 showed a link between volcanic activity and the retreat of the Cordilleran Ice Sheet, which once covered large portions of western North America, during times of rapid climate warming. A study of Iceland's volcanic systems showed a similar pattern. Volcanoes experienced a period of heightened activity when the ice cap covering the island disappeared. The average eruption rates were found to be up to 100 times higher after the ice melted. Scientists now think that ice cover to volcanoes is like a cork in a champagne bottle. Remove the icy cork and boom, the eruptions begin.

Go home, climate science.  You're drunk.
