Japan has been rocked by hundreds of aftershocks since a massive magnitude 9.0 earthquake struck on March 11 at 2:46 p.m. Japan local time.
This map shows all aftershocks above magnitude 5.0, but you can also see a series of “smaller” quakes, starting several days earlier.

There is nothing more mobile than the Earth actually moving under us.
Worldwide we’ve experienced a series of large quakes in 2010 so far. The latest occurred Sunday in Baja, California. Here in L.A., many felt a rolling sensation akin to being on a ship at sea.
In Baja, the 7.2 magnitude quake caused large amounts of obvious damage, and many Mexicali residents have fled north after hundred of aftershocks struck the region.

Will we get swallowed?
The Puente Hills thrust fault, which appeared to be responsible for Tuesday’s predawn magnitude 4.4 earthquake that shook much of the Los Angeles area, is capable of generating earthquakes up to magnitude 7.5 — massive shakers
Sue Hough, a seismologist in the Pasadena office of the U.S. Geological Survey, added: “This is the fault that could eat L.A.”

Sometimes in SoCal, you are literally jolted out of bed.
This morning a 4.4 magnitude earthquake struck in Pico Rivera, just south east of Downtown L.A. No major damage or injuries were reported.
But we were certainly woken up, lied there in bed, wondering if we should run for a doorway. We were also alerted to the fact that it might be time to update the earthquake supply kit. Immediately headed to Facebook and Twitter on our mobile phones to see how everyone was doing at 4:04 a.m.
