I know what this is.
I remember a few years back, some stories of how the government had drilled down and planted explosives around Yellowstone, and were going to set it off and trigger a world calamity for the one world government take over.
In reality, this is Obamas "October" surprise. He's going to set off some volcanoes in S Kalifornicate, decimate the Salton Sea, enact martial law and suspend the election.
Hows that?
glad earthquake-report.com did some history digging. answered the "normal" question for me (as of now) Update 21:44 UTC - The last comparable seismic swarm in Brawley dates from 1970. Another one occurred in the 1930′s - Some buildings in Brawley were evacuated after the first stronger quakes. People will probably stay outside for a while which is good in case other even stronger quakes would strike. - The Brawley zone is a complex seismic area of smaller faults. The San Andreas main Fault runs from near Palm Springs to enter Mexico just west of Yuma.
