I read those, mostly innuendo and fluff. Small events on the surface (hurricanes are tiny on a planet scale) might cause small shallow eq’s, maybe, Haiti, no. Listen I get it, the coincidence seems odd but that is all it is. I am not disparaging your curiosity. It was an excellent question to ask. Being a weather noob, it was nice to be able to respond intelligently for once.
no to air pressure but that another good question. The forces and masses of the objects involved are truly massive. I mean how much does tectonic plate weigh? I could look it up but its a lot and the forces involved are huge. So things on the surface that seem impressive to us are tiny and generally insignificant to tectonic plates. Air pressure changes are too small to kick one off.
oh and I like the dead, not as my wife does but I like them. I am building up my vinyl collection and American Beauty the first dead LP on my list.
