Sumatra 7.7

Initially I just put a comment on the Baja California 7.2 thread. But not only is this one bigger, it deserves coverage with it’s own maps. This quake is on the same system that gave us the lethal tsunami a while back, but this time not so much…

California Map

Just because I’m here…

The aftershocks of the Baja quake continue to look to me like they are spread out toward the L.A. basin. Relieving stress toward the San Andreas.

That “Barycenter” predictive thing seems to have some merit. Here we are in a Major Minimum with the Sun at low angular momentum and we’ve got quakes going off all over the place. Yeah, “correlation is not causality”, but…

Volcanos? Why not – Here Are Some Maps

I like this nice interactive global volcano map. You can click on a volcano and get a report about it.

The USGA US Volcano Status map gives a more focused look at the US action.

    And we get a 5.7 in Taiwan…

    Round and round it goes, where it stops, nobody knows…

    Looks like either an alternation of sides of the Pacific Plate or a rotation around the plate to me. I’d go for “alternating sides” if I had to pick. So, that would mean “We’re up” next over here on the N. America side. 2 weeks? or 4?
