Following a magnitude 6.6 earthquake in the Pacific, a tsunami threat was issued for California, Oregon, Washington, Alaska, and Hawaii along the west coast of the United States and Canada. Within a few hours following the initial earthquake, all threats of a tsunami were retracted and the warning was dialed back to a notification.
Since California is amongst the most significant points of impact if a tsunami were triggered by a seismic event in the Pacific, California’s earthquake and tsunami response systems have been some of the first to assess the risk.
The earthquake mentioned here today has been documented by USGS, CalTech, EarthquakeTrack, Pacific Northwest Seismic Network, and other contributors within California’s extensive seismic research programs – all credible and globally recognized seismic activity monitoring systems. UTC is an abbreviation for Coordinated Universal Time. Anyone with the MyShake App was alerted for the following quakes. There is no need to panic since seismic activity along the San Andreas Fault Line is normal.

While earthquakes in this part of the Pacific are common, the region regularly has some of the most powerful earthquakes in the world. Tsunami warnings, when issued, are taken very seriously.
