Hi Chris. Thanks a bunch. Got your email and have to agree.

“OK, on the field trip Tom Rockwell said that a lady slept through the Izmit earthquake even though it slipped 5 m in her backyard. There was a shelf with delicate objects on it that did not tip over...nor did the delicate objects. Tom thinks that it was areas with discontinuities that produced the strong motion...in certain areas with smooth straight fault the motion was small.”

I have a problem with this. What happened to the “L” and “R” waves? They travel along the surface and are the cause of the violent shaking we feel at a distance from the epicenter of a quake. What could have possibly canceled those waves at her location? Take Care…Don in creepy town
