Early morning earthquakes shake Shasta Dam

Shasta Lake, Calif. -

Eight earthquakes occurred between the hours of 5:30 a.m. and 11:30 a.m. Tuesday morning.

The strongest of which occurred within five miles of the dam itself. 

The quakes were very weak, generally too weak for people to feel, and ranged in strength from 1.9 to a 2.3 on the Richter Scale.

Officials say that the dam is designed to withstand a 6.0 quake and has seen much stronger earthquakes before.

They also say that Shasta Dam is a gravity type dam, which means the sheer mass of the dam itself holds back the water. 

Dam officials say that type of dam is also more resistant to earthquake damage than earthen or arch dams.

In 1998 a 5.4 magnitude earthquake struck only five miles from Shasta Dam and in 2006 a 3.0 quake struck within a mile of the dam.

Neither earthquake caused any damage.
