At 7:58 in the morning of June 18, 2018, an earthquake centered in the north of Osaka Prefecture caused shaking of lower 6 on the Japanese seismic intensity scale in the city of Takatsuki, Osaka’s Kita Ward, and nearby areas. Upper 5 intensity shaking was recorded in Kameoka, Kyoto Prefecture, and other municipalities. The Japan Meteorological Agency estimated the temblor’s magnitude as 5.9, later upgrading it to 6.1. The hypocenter was a relatively shallow 13 kilometers below the surface, as the earthquake took place in the crust close to the Arima-Takatsuki Fault.
The Great Hanshin-Awaji Earthquake of January 17, 1995, was centered in the south of Hyōgo Prefecture, to the west of Osaka. It was the first temblor with seismic intensity of 7 since records began and caused devastation in Kobe and the surrounding area.
JMA records indicate that there have been 52 earthquakes with seismic intensity of lower 6 or above since the Great Hanshin-Awaji Earthquake. Of these, five hit intensity 7, the top score on the scale that measures shaking at a certain point on the surface. (The magnitude, meanwhile, expresses the total energy released in a quake.)Earthquakes of Lower 6 Intensity or Above Since the Great East Japan Earthquake
