Strong Earthquake Rocks Sacramento Valley and Surrounding Areas.

A 5.5-magnitude earthquake hit near Lake Almanor, northeast of Chico, and was felt all over Sacramento Valley. The quake was originally rated a 5.5-magnitude shaker, then downgraded to a 5.4, and has been re-graded as a 5.5. There have been no reports of damage or injuries. A series of five much smaller aftershocks have been recorded by USGS, none bigger than a 3.0 magnitude. Experts with the USGS say there is a very small chance that the main 5.5-magnitude quake will be followed by a larger earthquake in the next three days.
