On September 13, according to Xinhua, an earthquake with a magnitude of more than 5 occurred in the Ryukyu Islands area of Japan, with the epicenter determined by international seismic agencies at different depths.
According to the US Geological Survey (USGS), the earthquake occurred at 8:32 pm GMT on September 12, in an area about 101km south of Yudomari in Japan. USGS estimates the earthquake to be magnitude 5.1, with the epicenter located at a depth of 45.5km, at coordinates 29.32 degrees North latitude and 130.38 degrees East longitude.
Meanwhile, the German Geological Science Research Center (GFZ) also recorded an earthquake occurring at the same time in the Ryukyu Islands area. This agency estimates the magnitude of the earthquake to be 5.3 degrees, with the epicenter at a depth of 10km, at coordinates 29.18 degrees North latitude and 130.42 degrees East longitude.
Information from the Malaysian Meteorological Agency (MetMalaysia) said that the earthquake was recorded at about 4:33 am on September 13 (local time). The agency determined the epicenter at 29.5 degrees North latitude and 130.6 degrees East longitude, about 231km south of Kagoshima, Japan, at a depth of about 40km.
MetMalaysia's initial assessment shows that the earthquake did not pose a tsunami risk for Malaysia.
The Ryukyu Islands are located in southwest Japan. This area is located in an area with significant seismic activity, due to its proximity to the tectonic plate boundaries.
The USGS and GFZ setting different intensity and depth levels is not unusual in initial earthquake assessments. The parameters can be adjusted as the seismic agency continues to collect and analyze data from multiple monitoring stations.
There is currently no information in the sources cited about damage or casualties caused by the earthquake.
