Enlarged map of the Kumamoto area. Beginning in April 2016, a series of shallow, moderate to large earthquakes with associated strong aftershocks struck the Kumamoto area of Kyushu, SW Japan. What makes an earthquake "significant"? Kyushu as a whole was shaken to varying degrees depending on proximity to the epicenter. The epicenter was at 32°44.5′N, 130°48.5′E, at a depth of about 11 km below ground and the magnitude measured 6.5 (Mj). For the first large earthquake with a JMA magnitude of 6.5 (21:26, April 14, 2016, JST), the large strong motions are concen-trated near the epicenter and the strong-motion attenuations are well predicted by the empirical relation for crustal Japan’s chief cabinet secretary, Yoshihide Suga, told a … Japan Shakemap 15 April 2016.jpg 612 × 718; 96 KB.
