California has been alerted following back-to-back earthquakes in Japan and three other considerably volatile seismic events along the ‘Ring of Fire.’ No need to panic since no tsunami warning has been issued. Regardless, the US west coast remains on guard.

Historically, tsunamis impacting California and the west coast have been triggered by seismic activity along the Ring of Fire. The last damage-inducing tsunami was caused by a magnitude 9.2 earthquake in Alaska that sent waves surging down the US west coast.

Seismic activity is normal, and typically not alarming. When larger events occur, they're evaluated so people residing in an area of potential impact are alerted and made aware.

California, Oregon, and Washington have a new ‘MyShake’ app that acts as an early earthquake detection system along the San Andreas. MyShake employs the same technology that notifies people of potentially dangerous seismic activity around the world. While there is no fool-proof method of predicting seismic activity, modern technology will give us a good indication of anything worth worrying about.

The earthquakes reported below have stirred people living along the west coast of California, Oregon, and Washington. All earthquakes have been documented by USGS, one of the few credible and globally-recognized seismic activity monitoring systems. UTC is an abbreviation for Coordinated Universal Time.
