California Earthquake Radar


Hot in the earthquake news today is a presentation which shows how an Easter earthquake is still shoving dirt around in California.

Here we have a messy picture showing the motion.  It's a dog's breakfast of motion in all directions.  In the earthquake, some ground moved the opposite direction from the main fault.  This can be expected at various gaps.  The news says some gaps of over 7 miles were 'jumped'.

I don't know that this takes us anywhere, but it shows things are terribly complex.  From a map of motions, I wouldn't dare consider where the next earthquake will take place.  Is it in the zones of no motion, lots of motion, weird motion???  My thoughts are that the rock down there is just a big sandpile of broken rock, and you can't get much from the surface geology.

OMG! I just moved into the Google 'Blogs related to earthquake' box, when doing a blog search on 'earthquake'. Wow! And I thought they hated me!
