6.1 Magnitude Earthquake Hits Japan, Strong Tremors Felt Across Iwate and Aomori

A 6.1 magnitude earthquake struck off the coast of Iwate Prefecture in northeastern Japan early Sunday, rattling several prefectures but causing no immediate reports of casualties or significant damage. The Japan Meteorological Agency (JMA) confirmed that no tsunami warning was issued and urged residents to remain alert for possible aftershocks.

The earthquake occurred at 7:25 am local time at a depth of about 40 kilometres beneath the Pacific Ocean. Strong shaking was felt across Iwate , Aomori , and nearby areas, reaching Lower 5 on Japan's seven level seismic intensity scale in parts of the affected region. The level indicates strong shaking that can move unsecured furniture but typically causes only limited structural damage.

Japanese authorities said no abnormalities were detected at nuclear power plants or other nuclear facilities , while the government continued to monitor the situation through its emergency response system. Officials also reported no immediate disruption to essential infrastructure following Sunday's tremor.

The latest earthquake comes just three days after a 7.2 magnitude earthquake struck nearly the same offshore region. That earlier quake left eight people with minor injuries , temporarily halted Shinkansen bullet train services and prompted inspections of roads and railway infrastructure before operations resumed. On Friday, a separate 5.6 magnitude earthquake also shook Yamanashi Prefecture , west of Tokyo near Mount Fuji .

The JMA has warned that additional earthquakes may occur in the coming days. With typhoon season underway, officials have also cautioned that repeated seismic activity could increase the risk of landslides and mudslides in areas saturated by heavy rainfall. Japan, located along the Pacific Ring of Fire , is among the world's most earthquake prone countries.
