‘Shook the whole house.’ 3.3-magnitude earthquake rattles Northern California

A 3.3-magnitude earthquake rattled parts of Northern California as some people were getting ready for bed, geologists said.

The earthquake shook near Cloverdale at about 10 p.m. Monday, April 18, according to the U.S. Geological Survey. It was about 1 mile deep.

The 3.3 magnitude may not be as strong as some California residents are used to, but more than 150 people still reported feeling the quake to the USGS.

“Just had an earthquake in Cloverdale, shook the whole house,” one person said on Twitter.

Magnitude measures the energy released at the source of the earthquake, the U.S. Geological Survey says. It replaces the old Richter scale.

Quakes between 2.5 and 5.4 magnitude are often felt but rarely cause much damage, according to Michigan Tech. Quakes below 2.5 magnitude are seldom felt by most people.

Cloverdale is about 115 miles northwest of Sacramento.
