BIG earthquakes 04/11-12/2012. 8.2/8.6 SUMATRA, 6.5 MEXICO,6.2/6.9 GULF OF CALIFORNIA, 5.9 OREGON

Wow, these last couple days have been very active! Call me a "fear monger" but this is a lot of large quakes in 2 days. I wouldn't normally post a thread just based on a couple quakes, but this seems very ramped up IMO.

We have (2) 8.0+ in Sumatra on the 11th, with a 6.0 in the Indian ocean in between. (prolly related) Then a 5.9 off the coast of Oregon, then a 6.5 in Mexico, then a 6.2 and 6.9 on the gulf of California just now. What's goin on?

Here's the data from USGS:

Type: Earthquake

Magnitude: 6.9
DateTime: Thursday April 12 2012, 07:15:48 UTC
Region: Gulf Of California
Depth: 10 km
Source: CSEM-EMSC Feed

Due to the coordinates on the Mexico quake vs the Gulf of Cali quakes it seems as though they all might be related to each other, although the first Mexico quake is quite a bit (significantly) south of the last most recent two.

Also, I'm really surprised we haven't heard much on ATS about the 5.9 off the coast of Oregon. I wonder if Westcoast felt it!

Just been another 7.1 mexico.

Wow, I have not seen that on USGS yet. What EQ tracker are you using?

reply to post by TheMindWar


I'm thinking they have either upgraded the latest gulf of Cali quake to a 7.1 or downgraded one of the "Mexico" quakes, because I'm still not seeing a new 7.1 on USGS.

and we've barely started April 12, 2012

i got a feeling 4/12 today is gonna have alot of activity the next 24-72hrs as well

dunno why- solar activity? magnetosphere? or what...

reply to post by Wookiep


the Mayan prophecy that was taught to me ,says that on 3/21 of this year ( the spring equinox) the beginning of the shift would begin to accelerate. increased Earthquake activity is to be expected ,to the acme @ winter solstice time, and then waining until the spring eqinox ( 3/21) of 2013. Hope you Enjoy the Rides !!!

Well I need to head to bed now (2:25am MST) but I'll be checking up on this for sure. It seems a little strange to me, but what do I know. Please feel free to update!

This is why I hate living in Southern California. Constant fear of "The Big One" (the San Andreas Slipfault) rupturing. I'm pretty much certain that WHEN it goes (not a question of IF), it's going to be at LEAST a 9.0+. Hell, for 30 years they have been saying it's capable of a 7.0+.. then an 8.0+.. and after the Japan quake hit, a new USGS study got released, saying the San Andreas is capable of a 9.0+ Yea, no sh*t.


I wish I lived in Australia.

Well I can only speak for myself, but so far atleast in Sumatra there has been no major issues(tsunami) and here in california i did not feel the mexico quakes. But the earth is releasing this energy, as opposed to building it up further......just trying to find a silver lining

its looking crazy, quake squares all over the west coast,



and even one in the northeast USA

Looks like things have calmed down a bit (for now). Aftershocks on Gulf of Cali finally. What a crazy couple days. As expected, very little mention from the media.
