Recent Earthquake Activity in Japan

Tokyo: A significant earthquake measuring 7.1 on the Richter scale struck southwestern Japan on Tuesday. According to the nation's meteorological agency, tsunami warnings have been issued for the Ariake and Yatsushiro seas, as reported by local news outlets.

The quake hit Kumamoto Prefecture at a depth of 10 kilometers at 4:27 p.m. local time, as per Japan's Kyodo News, citing the Meteorological Agency.

Previously, on June 26, a 5.6-magnitude earthquake caused minor injuries to 10 individuals in the central prefecture of Yamanashi and surrounding regions.

This earlier quake occurred at a depth of approximately 20 kilometers and registered a lower 6 on Japan's seismic intensity scale of 7 in Fujikawaguchiko Town, while Otsuki City experienced an upper 5 level, according to the Japan Meteorological Agency (JMA). Yamanashi Prefecture is notably home to Mount Fuji.

An intensity rating of lower 6 indicates that standing becomes challenging, unsecured items may fall, and windows could sustain damage, as reported by Kyodo News, referencing the agency.

The last occurrence of such shaking in Yamanashi was recorded in 1924, raising concerns about potential volcanic activity at Mount Fuji. However, the JMA confirmed that no unusual volcanic activity had been detected following the quake, according to Xinhua News Agency.

The tremors were felt in Kanagawa and Shizuoka prefectures, as well as in Tokyo, but no tsunami alert was issued.

On June 25, another earthquake with an initial magnitude of 6.9 shook Iwate Prefecture, as stated by the country's weather agency.

This quake struck the eastern coast of Iwate at a depth of around 50 kilometers, registering upper 6 on Japan's seismic scale of 7 in Hashikami Town, Aomori Prefecture, according to the JMA. The tremors were distinctly felt in Tokyo, with the epicenter located at 40.2 degrees north latitude and 142.3 degrees east longitude.
