Earthquake Rocks Southern California

Screams rang out during a family get together over the holiday weekend.

Youtube footage shows youngsters playing with their toy cars and a woman stacking wooden blocks, then, pandemonium.

In another home, the force of the quake was so extreme it looked like the swimming pool had a wave machine.

"It's like a tsunami in the pool," said an onlooker.

Lampshades were swinging in homes. Walls trembled.

One video is actually so dramatic some Internet postings are suggesting it may be staged.

Although the 7.2 quake was centered on the Mexican side of the border, it was felt as far away as Los Angeles and Phoenix.

Fears of an apocalypse like the one featured in the movie 2012 have been triggered by a series of events around the globe.

First there was Haiti, then the 8.8 quake in Chile. 

Soon after the top searches on yahoo.com included "doomsday," "apocalypse" and "Armageddon."

But don't panic yet. Scientists say the recent quakes are just part of a regular cycle, not a warning of impending doom.
