Registering a magnitude of Ms 6.3, the earthquake destroyed Otaki (Japanese: 王滝(おうたき)), and triggered major landslides.

Since, there was no seismometer in the area Japan Meteorological Agency made an estimate intensity Shindo 6.

[6] A seismometer at Makio Dam, 4 km (2 mi) away from the epicenter observed very strong shaking but could not record more than 0.3 g which was the limit.

Due to torrential rains in the area before the earthquake, many landslides occurred.

Nine check dams were built on Mount Ontake in four years after the earthquake.
