#physics #earthquake **Two branches to continental earthquake** I'm expecting a third, like New Madrid, but we can live with just two. It's an amazing pattern, with both mechanisms the same. The whole area has been wrenched apart, and we await the gps and strong ground motions to see the mechanism. Usually, the existing topography will be reinforced. The lows lower and highs higher.

@RobinLacassin I guess we would call that a wrench fault, since it is not pure strike-slip or extension. The tectonics looks like that, as well. We need the strong ground motion.

@RobinLacassin The usgs has it as normal, and I found only one big one. But lots of places have it at two.

@pwinn Wow, the AI could write a whole scientific paper like that.

@rrb I think removing child porn costs another buck or two.

@jaysonmassey I always found that if you posed the question to the uppers, like 'Can we suffer a little bit of change for better security, they would kill you.

@braindouche When I was a kid, they were the world capital for buildings burning down.

**Bell direct fiber internet** When they sunk their billion dollars to put fiber to the home, I was one of the first to sign. Then I didn't constantly check their new prices. So now, I went to 50% higher speed for less price. I must have been overpaying for a while now.
I'm not complaining since it could be like the Old Man with a tin can and a string.

#physics #earthquake **acceleration** At about .6g. I consider this to be not as important as the pgv. Earthquake design uses accel which is long and wobbly, thus they design for resonance. The velocity is a big nasty pulse, and more accurately relates to the base shear.

#physics #earthquake **Turkey strong ground motion** I'm having a tough time figuring this out, but this is PGV in the basin that dropped. A pulse of 120 cm/s is about as strong as you can get and no structure can stand against it.

#earthquake **Buffalo earthquake** Very tiny. It reflects a major fault under Hamilton. It is activated by a seep of lake water.

#physics #earthquake **Aftershocks** These aftershocks define the fault zone. There was only one big quake, and the second was an M6. You need more strong ground motion sensors to define the mechanics.

#physics #earthquake **The two nearly identical earthquakes looks to have a mechanism of first, one side dropping, and then the other.

#physics #earthquake **Expanding basin** The whole place is a hot zone for earthquakes.

#earthquake **Turkey Tectonics** At the epicentre, we have extension as the Arabian plate pushes in.

#earthquake **Extension earthquake in Turkey** You can see very complex tectonics here. This was a shallow extension (basin) earthquake that would have sent out a wide swathe of lower frequency ground motion.

#physics #weather **Siberian cold pours down on Turkey** Not good.

@freemo Just say no.

Much better if the balloon exploded at the top.
