Earthquake off the Ogasawara Islands
An earthquake with a magnitude of 7 occurred off the Japanese Ogasawara Islands. This was reported by the Japan Meteorological Agency, which serves as the country's seismic service. No tsunami threat was issued.
Details of the seismic event
According to the agency, the hypocenter of the seismic event was located at a depth of 470 km beneath the Pacific Ocean floor. There was no information about casualties or damage at the time of publication. The Ogasawara archipelago is located 1,200 km south of Tokyo; only two islands are inhabited, with a total population of about 2,500 people.
Context of recent earthquakes
Gazeta.Ru reminds readers that on October 24, an earthquake with a magnitude of 5.3 occurred in Qinghai province in northwestern China: tremors were recorded at 16:39 (11:39 Moscow time) at a depth of 10 km. Before that, an earthquake with a magnitude of 7.7 occurred in Panama — eyewitnesses filmed damaged and destroyed houses, roads, and hotels on video, and a massive power outage occurred in the central provinces of Herrera, Los Santos, and Veraguas. Earlier, a strong earthquake was also reported in the Tibet Autonomous Region of China.
Significance of the event
Despite the high magnitude, the great depth of the hypocenter — 470 km — usually reduces the strength of tremors felt at the surface, which is consistent with the absence of an issued tsunami threat. The event primarily affects residents of the two inhabited islands of the archipelago, with a population of about 2,500 people. In practical terms, this means that, judging by reports, no special response measures were needed given the absence of data on damage, but the final consequences have not yet been confirmed.
