An 8.7 magnitude earthquake struck off the east coast of Kamchatka, Russia on Tuesday evening according to the National Oceanic and Atmospheric Administration (NOAA), prompting a Tsunami Watch for the Oregon coast and other west coast regions.
Other areas had Tsunami warnings and advisories in place as well. View the alerts and a map online.
Those near the coast were urged to monitor tsunami.gov.
"If you are in a Tsunami Watch area, prepare to take action and stay alert for further information," the agency said.
A tsunami warning means a distant tsunami is possible. Should one be generated and strike the Oregon coast, the current assessment is that it would strike between 11:40 and 11:55 p.m. Pacific Time, according to the watch.
