Shindo 5+ was recorded in parts of Ehime and Yamaguchi Prefectures, while Shindo 5- was observed in multiple areas of Shimane, Kōchi and Ōita Prefectures; Shindo 1-4 was also reported in Kyushu, Kansai and Chūbu regions, with shaking recorded as far away as Shizuoka, Noto, Ishikawa, Iizuna and Kōzushima, Tokyo. A maximum peak ground acceleration of 832 gal (0.85 g) was recorded at Saeki-ku, Hiroshima; strong ground motions from the earthquake were amplified and spread to areas far from the epicenter, due to the ground beneath the region comprising soft sediments.芸予地震 http://www.chugoku-np.co.jp/geiyo/frame.html ja https://web.archive.org/web/20070819165416/http://www.chugoku-np.co.jp/geiyo/frame.html 19 August 2007 dead 2 April 2001 1 February 2025 chugoku-np.co.jp On the Modified Mercalli intensity scale, the earthquake registered a maximum intensity of IX (Violent).https://www.ngdc.noaa.gov/hazel/view/hazards/earthquake/event-more-info/5596 National Geophysical Data Center / World Data Service (NGDC/WDS): NCEI/WDS Global Significant Earthquake Database NOAA National Centers for Environmental Information 10.7289/V5TD9V7K 1 February 2025 NOAA 1972 Tremors were also felt along the eastern and southern coasts of South Korea.https://www.independent.co.uk/news/world/asia/at-least-two-die-as-strong-earthquake-hits-japan-688814.html At least two die as strong earthquake hits Japan Hall K.
