Quick Look
- At around 1:04 a.m. on the 8th, there was a magnitude 5.7 earthquake with its epicenter in western Shizuoka Prefecture, and a seismic intensity of 5+ was observed in Chita City, Aichi Prefecture.
- Thirteen people were transported in Aichi Prefecture and other areas, causing delays on the Tokaido Shinkansen.
- The Japan Meteorological Agency is warning of earthquakes with a maximum seismic intensity of 5 or above for the next week.

Why It Matters
This is the first time in about 30 years that a seismic intensity of 5 or higher was observed in Aichi Prefecture, since an earthquake in the eastern part of the prefecture in March 1997 (magnitude 5.9).
At around 1:04 a.m. on the 8th, there was an earthquake with its epicenter in western Shizuoka Prefecture, and shaking with a seismic intensity of 5+ was observed in Chita City, Aichi Prefecture. According to the Japan Meteorological Agency, the depth of the epicenter was 41 km, and the magnitude of the earthquake (magnitude M) was estimated to be 5.7.
Earthquake intensity 3 in Fukushima
According to the Nagoya City Fire Department, 13 people were transported to the hospital after falling at home. Many other people were injured in Aichi and Shizuoka prefectures.
According to JR Tokai, the Tokaido Shinkansen was operated at a reduced speed from the first train, resulting in delays for some trains.
Ayaki Ebita, head of the Earthquake and Tsunami Monitoring Division at the agency, held a press conference and explained that the epicenter of the earthquake was inside the ocean-side (Philippine Sea) plate that subducts beneath the land-side plate, and that the mechanism is different from the Nankai Trough earthquake, which occurs when the boundary between two plates suddenly slides. Because M is relatively small, it is unlikely that it will cause any significant changes in the boundaries between the plates. ``In areas where the shaking was strong, please be careful of earthquakes with a maximum seismic intensity of 5-plus over the next week.''
It has been about 30 years since Aichi Prefecture observed a seismic intensity of 5 or higher, since an earthquake in the eastern part of the prefecture (M5.9) in March 1997. The reason the shaking was stronger than in western Shizuoka Prefecture is believed to be due to the influence of the ground.
The seismic intensity in major areas is as follows:
Earthquake intensity 5+ = Chita City, Aichi Prefecture
Seismic intensity lower 5 = Seto City, Aichi Prefecture, Uriki Village, Nagano Prefecture, Ena City, Gifu Prefecture, Hamamatsu City
Seismic intensity 4 = Nagoya City, Iida City, Nagano Prefecture, Tajimi City, Gifu Prefecture, Iwata City, Shizuoka Prefecture, Kisosaki Town, Mie Prefecture
Earthquake intensity 3 = Tsu City, Fukui City, Hokuto City, Yamanashi Prefecture, Otsu City, Kyoto City, Shijonawate City, Osaka Prefecture, Toyooka City, Hyogo Prefecture, Takatori Town, Nara Prefecture.
