A significant earthquake with a preliminary magnitude of 7.0 struck near Tokyo, Japan, on Thursday evening local time, according to the Japan Meteorological Agency (JMA). The earthquake occurred at a depth of approximately 60 kilometers (37 miles).
Tsunami Advisory Issued
The Japanese government issued a tsunami advisory for the coastal areas of Ibaraki and Chiba prefectures, warning of possible waves up to one meter (three feet). Residents in affected coastal zones were urged to evacuate to higher ground as a precautionary measure.
Widespread Swaying and Emergency Protocols
Reports from the Tokyo metropolitan area indicate widespread building swaying, which led to the activation of emergency protocols. Public transportation, including Shinkansen bullet train services and local subway lines, was temporarily halted for safety inspections. Several expressways were also closed to traffic.
Initial Reports on Damage and Casualties
No immediate reports of major structural damage or casualties have been confirmed. However, local fire departments reported receiving several calls regarding minor injuries, primarily from falls and debris. Power outages were reported in some districts of Tokyo, affecting thousands of households briefly before services were partially restored.
Government and Nuclear Response
The Japanese government has established an emergency response center. Prime Minister's Office officials are gathering information on the situation. The country's nuclear regulatory authority stated that there were no abnormalities reported at any of the nuclear power plants in the affected region.
Discrepancy in Magnitude Readings
The U.S. Geological Survey (USGS) recorded the event with a magnitude of 6.9, a slight discrepancy from the JMA's initial 7.0 reading. Both agencies continue to monitor the situation for aftershocks.
