A magnitude 7.4 earthquake that occurred off the east coast of Kamchatka, Russia: Tsunami watch has been canceled for Hawaii
The earthquake occurred at 8:49 p.m. Hawaii time, and was initially reported at magnitude 7.5.
A tsunami watch has been canceled for Hawaii following a magnitude 7.4 earthquake that occurred off the east coast of Kamchatka, Russia.
The watch was issued at 9:03 p.m. and canceled at 9:42 p.m. after the Pacific Tsunami Warning Center determined that, based on all available data, there was no tsunami threat to Hawaii.
Within minutes of an earthquake, they can issue messages that provide alert levels (warning, advisory, watch, information statement), preliminary information about the earthquake, and an evaluation of the threat.
Messages are updated regularly throughout an event as information becomes available.
A tsunami watch is issued when an earthquake occurs that could generate a tsunami. Prepare to take action if the watch is upgraded to a advisory or warning.
A tsunami advisory is upgraded from a watch if a potential tsunami could cause strong currents or dangerous waves. Widespread inundation is not expected. Stay away from beaches and waterways.
A tsunami warning is issued if significant, widespread inundation is imminent or expected with dangerous coastal flooding and currents. Take urgent action to protect life and property, including evacuations.
Warning center scientists use an earthquake’s preliminary seismic information to decide if an earthquake could have generated a tsunami.
