Shake, Rattle and Roll

Shortly before lunch today the whole office started to shake and rattle. I had my headphones off and was in the zone - but my monitor and desk started jumping about definitely caught my attention. I think this is the third or fourth quake that has occurred during the work day. This one was fairly short ( 10 or 15 seconds) but I think it was the strongest one to date.

The current CNN headline is Earthquake serves as warning for L.A.

Uh, no thanks! We have had more than enough fun with the fires. Let's take a pass on the Big One earthquake.

LOS ANGELES (Reuters) - An earthquake struck just east of Los Angeles on Tuesday, rocking tall buildings and rattling nerves across Southern California, but causing no serious injuries or major structural damage.

The quake hit at 11:42 a.m. local time (7: 42 p.m. BST) about 30 miles (48 km) east of Los Angeles in suburban Chino Hills and registered magnitude 5.4 -- making it the strongest seismic event centred near America's second-largest city since the 6.7-magnitude Northridge quake in 1994.

It was followed in the next few hours by more than 50 aftershocks, the largest measuring 3.6, and geologists said there is a chance it could be a foreshock to a larger earthquake.
