One vernal cave pool in death vally had 4 foot waves 75 minutes after the quake in Mexico, they also have wave activity after quakes in South America, Japan and the South Pacific islands, plate tectonics are interesting I have been interesred in them since the late 1960's, that pool is 1,300 miles from the epicenter from the quake of 7.7 on the 19 of September, and of course Mexican humor says that
Y retiembla la tierra en su centro al sonoro rugir del "temblor"
(And the earth trembles in it's center at the loud roar from the quake)
These are words that are part of the Mexican him, except for the "temblor" it should be cañon "canon", humor in Mexico is unic.
