The region, like most of California is earthquake prone. Actually, on any given week there are small quakes in the region, registering under 3 on the Richter Scale. The tremors are so faint, no one feels them.
However, that was not the case on May 23, 2006, when an earthquake struck the east shore of Lake Almanor at 8:47 p.m. It got everyones attention as it measured 5.7. It was widely felt throughout the region.
In the spring of 1914, a swarm of earthquakes hit the region, a prelude to Lassen Peak’s eruption that May. At the same time, Big Meadows was being flooded to be transformed into Lake Almanor. Many locals believed that was cause of the Lassen Peak eruption.
