A magnitude 5.7 earthquake struck central Japan early Sunday, November 8, 2026, prompting authorities to introduce additional landslide precautions in parts of Aichi Prefecture. The earthquake originated in western Shizuoka Prefecture at approximately 1:04 a.m. local time.

The Japan Meteorological Agency (JMA) recorded the earthquake at magnitude 5.7. The US Geological Survey (USGS) reported a magnitude of 5.5. Smaller aftershocks were also reported.

The earthquake shattered shop windows, scattered glass across streets and sent books falling from shelves. Local television footage showed damage to commercial buildings and disruption in affected communities.

Earthquake Hits Shizuoka, Strong Shaking Recorded in Aichi

The earthquake occurred approximately 40 kilometres below the Earth's surface in Shizuoka Prefecture. Its effects extended across Aichi, Gifu and Yamanashi prefectures, as well as areas around Hamamatsu, Kyoto and Nara.

Aichi experienced the strongest shaking. According to the JMA, the maximum seismic intensity reached 5-plus in parts of the prefecture.

Magnitude and seismic intensity measure different aspects of an earthquake. Magnitude indicates the overall size of the event, while seismic intensity describes the strength of shaking at specific locations.

JMA Lowers Landslide Warning Thresholds in Aichi

The JMA has introduced temporary changes to landslide warning criteria following the earthquake. The agency said strong shaking could weaken the ground and increase the risk of landslides during rainfall.

Under the provisional arrangement, the warning thresholds will be reduced to 80% of their normal levels in Chita City, Aichi Prefecture.

The changes cover Level 4 landslide warnings, Level 3 landslide warnings and Level 2 landslide advisories.

The agency said it would continue examining the relationship between rainfall after the earthquake and landslide activity. The temporary criteria may be revised as further information becomes available.

Authorities Monitor Aftershocks and Nankai Trough Risk

The JMA has advised residents to remain alert for potentially strong earthquakes during the following week, particularly over the next two to three days. Officials have also warned about falling rocks, mudslides and rainfall-related hazards.

Agency official Ayataka Ebita said no apparent change had been detected in the Nankai Trough plate following the earthquake. The offshore seismic zone is recognised for its potential to generate major earthquakes. However, the latest tremor does not establish that a major earthquake is imminent.

Shinkansen bullet trains operated at reduced speeds in affected areas as a precaution while railway infrastructure remained under observation.

Japan is located along the seismically active Pacific Ring of Fire. Authorities regularly advise households to maintain emergency supplies, including drinking water, food and batteries, and to prepare evacuation plans.
