Japan: Magnitude 6.9 Earthquake in the South-Southeast Offshore Area of Shizuoka (Update)

[Asia Economy Reporter Dongwoo Lee] The Korea Meteorological Administration reported that a magnitude 6.9 earthquake occurred at 5:26 PM on the 18th in the sea area 892 km south-southeast of Shizuoka City, Shizuoka Prefecture, Japan.

The epicenter was located at 27.20 degrees north latitude and 140.70 degrees east longitude, with a depth of 490 km.

The Japan Meteorological Agency also reported the earthquake, stating that a seismic intensity of 4 was observed in the Ogasawara Islands, about 1,000 km away from Tokyo.

The seismic intensity scale used by the Japan Meteorological Agency is a relative concept that quantifies the degree of shaking felt by people or objects around during an earthquake, which is different from magnitude that indicates the absolute strength of the earthquake.

NHK reported that shaking with seismic intensities of 1 to 2 was detected across the Tohoku, Kanto, and Kyushu regions of Japan, and there is no concern of a tsunami caused by this earthquake.

The Japan Meteorological Agency has its own system to express seismic intensity strength in 10 levels, ranging from the normal state '0' to 1, 2, 3, 4, weak 5, strong 5, weak 6, strong 6, and 7.
