An earthquake of magnitude 4.0 occurred only 12 minutes ago 22 km southeast of Kashihara-shi, Japan, Japan's National Research Institute for Earth Science and Disaster Resilience (NIED) reported.
The quake hit at a great depth of 401.4 km beneath the epicenter near Kashihara-shi, Kashihara City, Nara, Japan, after midnight on Thursday, September 23rd, 2021, at 12:57 am local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In Yoshino-chō (pop. 8,800, 9 km away), Gojō (pop. 34,300, 19 km away), Sakurai (pop. 63,000, 20 km away), Gose (pop. 32,900, 21 km away), Kashihara-shi (pop. 124,500, 22 km away), Tenri (pop. 71,100, 29 km away), Nara (pop. 367,400, 41 km away), Ikoma (pop. 117,600, 44 km away), and Osaka (pop. 2,592,400, 55 km away), the quake was probably not felt.
