#physics #weather **New Zealand Storm** It's a direct hit.

#physics #weather **Gulf Stream unstable** It's like my dog's tail. Wagging down, now it is up.

#physics #weather The joy of a wind channel. This year, the Arctic air has decided to go through several wind channels, which open and close randomly. The big rains in Callie has a huge flow by Alaska. This is a smaller flow and may only soak north of callie.

#physics #weather Toronto is mild, from the tears of Vancouver. Those storms are hammering the west coast, and we get the dry warmth.

#physics #weather Finally back at home where I can type. New Zealand storm. This is the same type of prong as their last big rain, but it is curled. They should listen to the influencers that all this will be over soon -- ha ha.

#physics #weather New Zealand gets storm.

#weather. Up in Huntsville

#earthquake Aftershocks have settled.

#physics #earthquake **M6 coming for Turkey** This is what I was looking for. The geology has forced it up a bit. We need at least an M6 or 7 to close it up for another 300 years.

#physics #weather **Arctic ice volume** The daily weather is swirling in chaos, but things like ice volume are a natural integration of world temperature. I see a continuous recent rise in ice volume. Others might argue the reverse.

#physics #weather **Winds are a big swirly mess** No California storms.

#physics #earthquake **New earthquakes extending down to the sea** There is too much stress at that lower end. It should do something.

#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.

#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 **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.
