Wtf is going on in Iran the last couple days.

First they assassinate that Iranian general.

Then they missile several US facilities in response.

Then a Boeing passenger plane has a "malfunction" flying over Iran killing 177.

Now there's an earthquake at an Iran nuclear power plant?

Hmm. Next will Syria's Assad use Sarin gas on his own people again? It seems like all these pressure points are being hit at once, or things are just happening to line up that way. The earthquake is probably coincidence, and maybe the plane crash too, but it does seem like some geopolitical power is making a move on the chessboard right now.

iran can have horrible catastrophic earthquakes. there was a really bad one maybe 30 years ago? so lets hope not. i also read the airspace is now avoided by flights.

Iran is one of the most seismically active countries in the world, being crossed by several major faults that cover at least 90% of the country...

they probably had a hard time finding a spot for the power plant

There was also a 6.5 in Puerto Rico yesterday, and a 6.2 or something in Indonesia that same day. Seems like the whole earth has been quite seismically active in the last couple days.

I wonder how long it takes a strong shock from one side of the earth to reach the other side.

interesting q

primary waves aka p-waves:

Typical speeds are 330 m/s in air, 1450 m/s in water and about 5000 m/s in granite.

https://en.wikipedia.org/wiki/Seismic_wave

that's 15 machs in granite. three times faster than a scramjet

edit: so, 133 minutes or more.

Nice info, thanks! 2 hours, interesting. I wonder if the shocks can go through the core or if they have to go around the whole circumference.

I've seen info that during big earthquakes, the entire position of the center of mass of earth can shift by several centimeters, which is pretty crazy

if the core is molten it should be like a shock absorber. i also remember the seafloor can shift quite a lot, maybe a whole kilometer upwards causing a tsunami.

there must be videos of simulations online, the only question is how accurate those models are.

Yeah that makes sense to me too, so it'd basically have to go around the outside. Interesting about the seafloor, didn't know that

I can't help but think of the north korean "earthquake" that happened when one of their underground nuke tests went sideways...
