Japan's Meteorological Agency issued an alert predicting a magnitude-9.9 quake on 16 Oct 2026.
The alert, based on a magnitude-6.9 quake off Kamchatka, warned of shaking from Hokkaido to Tokai.
Ayataka Ebita said the epicenter was mislocated, so the agency cancelled the warning at 12:48 p.m. JST.

Only a shindo 1 tremor was recorded in Hakodate, yet the alert sparked anxiety.

History

Historical Context

The 17 January 1995 Great Hanshin earthquake struck near Kobe with magnitude 6.9, intensity 7, and killed over 5,000 people, making it Japan’s second deadliest quake after the 1923 Great Kanto event. In its wake, the Japan Meteorological Agency mechanized seismic-intensity monitoring (1996) and expanded early-warning planning for disaster management, shaping today’s response protocols.
