A powerful 7.5-magnitude earthquake struck Hawaii on Saturday night, triggering temporary chaos across the state. The tremor was caused by an earthquake off Russia’s Kamchatka Peninsula. The quake hit Hawaii at around 8:49 p.m. local time, and by 9:03 p.m., a tsunami watch was issued. However, the Pacific Tsunami Warning Center quickly assessed the seismic data and canceled the watch, assuring the public that there was no tsunami threat.

The cancellation of the watch brought widespread relief. Many residents expressed gratitude and relief online, with some telling others to “calm down” and resume enjoying their evening. The cancellation was based on seismic reviews that found no significant tsunami risk from the undersea quake. The warning center emphasized that no further updates would be issued unless new information became available.
Earlier that evening, Russia’s Kamchatka Peninsula experienced a series of strong quakes. The first was a 7.0 magnitude quake, followed by others ranging between 6.6 and 7.4. The Russian Ministry of Emergency Situations warned residents near the epicenter to stay away from the coast, though they noted the expected wave heights were not significant.

Historical context added to the anxiety: in 1952, a 9.0-magnitude quake in Kamchatka caused a devastating tsunami that hit Hawaii, destroying infrastructure and sweeping away boats and piers. This memory raised public awareness and concern despite the recent warning being lifted.
Even after the tsunami watch was canceled, locals advised caution. Social media users reminded others that ocean surges could still occur, urging people to avoid shoreline activities such as diving or collecting “opihi,” a native Hawaiian shellfish found on coastal rocks.
