6.0 Earthquake near La Paz 8 October 2012
Yet another quake along the undersea fault line in the Sea or Cortez.

Hour-long VIDEO located here. Note that HULU does insert an occasional brief commercial advertisement. BELOW animated GIF's are big and may take a moment to
load.
Future Movement
Past Movement
And for those of you that think earthquakes are sporadic events, here is a snapshot of a typical week's worth of shakers, albeit most are small and
not felt.

Interesting that altho there are quite a few movements on the border between US and Mexico, there are none shown in Baja itself.
Thank goodness.

Those gif's of the peninsula movement are really cool. Can I find enlarged version of those somewhere Bryan? Mesmerizing- I notice something new every
time I watch them and I'm not getting anything done do far this morning!
Did you notice the big collison with the peninsula and mainland around Los Mochis on the "Past" gif? You can see Baja slide under mainland and then Pt
Chivato and B.Concepcion emerge as the Sea opens up again.
Did this collison cause the Tres Virgenes to form and stimulate all the volcanic activity in our area or did the volcanism occur while Baja was still
attached to the mainland?
It looks like the Northern Sea of Cortez was cut off from the south when the land masses were attached?
So many questions that my poor husb doesn't have the answers to

Hi Blanca,
That's because the Baja Peninsula moves as "one piece"; essentially everything above water (and some below water) move on the same tectonic plate.
You're right ... thank goodness.
PS - the Salton Sea most likely will, in the future, connect with the Sea of Cortez; see also Lake Cahuilla "... the delta had reached the western shore of the Gulf of California (the Sea of Cortez) creating a massive dam which excluded
the sea from the northern reaches of the Gulf. Meandering at random across the ever-growing fan-shaped mass, the river changed its course
constantly."

Hi Oladulce,
Tectonics/volcanology/geography fascinate me when combined with history, culture & linguistics (ugh, way too much brain-food). It's really
remarkable how the history of this one small place on the globe fascinate each of us.
Here is the hour-long VIDEO located here. Note that HULU does insert an occasional brief commercial advertisement. And YES, I did notice the individual collision
points. Google earth does a fairly decent job at representing the world's tectonic plates (+/-), obviously obtaining the data from other professional
sources. And when you step back (up) and view our little round orb from above, it's easy to see where we are going (geographically) when you see where
we have been (geographically).
Now throw in sea level rise & fall (as the third dimension) and you can see how islands come and go; coastlines move back and forth; great
migrations occur; isolated peoples/flora/fauna develop unique and interesting characteristics (how do we spell Boojum?).
Lastly, are you familar with the Hawaiian Islands chain. How they move over a "hot spot" on the earth? this includes atolls, Midway Island, etc
towards the west and on up to the Aleution islands. I'm not the expert, but I suspect something similar WAS happening under Baja as she migrates
northwest; a hot spot under the Tres Virgenes? As I recall the 3V are actually now considered extinct?
Thanks for sharing. I love good intelligent conversation and dialog.
-Bryan
