7.5-Magnitude Earthquake Triggers Tsunami Watch in Hawaii, Later Canceled

A powerful 7.5-magnitude earthquake struck off Russia’s Kamchatka Peninsula Saturday night, sending tremors across Hawaii around 8:49 p.m. local time. By 9:03 p.m., the Pacific Tsunami Warning Center issued a tsunami watch, sparking brief panic statewide. However, the watch was canceled shortly after when seismic data showed no significant tsunami threat.

The swift cancellation brought relief, with many Hawaiians taking to social media to express gratitude and encourage others to “calm down” and resume their evening plans. Officials confirmed no further updates would be issued unless new information emerged.

Earlier, Kamchatka had been rocked by a series of strong earthquakes, ranging from 6.6 to 7.4 in magnitude. Russian authorities advised coastal residents to remain cautious but reported that significant tsunami waves were not expected.

The situation reignited memories of Hawaii’s tragic past—specifically the 1952 9.0-magnitude Kamchatka quake that generated a deadly tsunami, destroying infrastructure and killing residents in Hawaii. That history heightened anxiety even after the warning was lifted.

Despite the cancellation, locals urged continued caution, especially around coastal areas. Social media users warned against shoreline activities like diving or collecting opihi, reminding everyone that ocean surges can still occur without warning.
