Powerful 7.2-Magnitude Earthquake Rocks Northern Japan

A powerful 7.2-magnitude earthquake struck off the coast of northern Japan on Thursday morning (June 25), sending strong tremors across a wide area and briefly disrupting transportation services.

The quake hit at around 7:30am (local time) off the coast of Iwate Prefecture on Japan’s main island of Honshu. The tremor was strong enough to be felt in Tokyo, several hundred kilometres from the epicentre.

Japan’s Meteorological Agency (JMA) initially measured the quake at 6.9 magnitude before revising it upward to 7.2, stating that the earthquake originated at a depth of 44 kilometres beneath the seabed.

Despite the intensity of the shaking, authorities reported no immediate fatalities or major structural damage, and no tsunami warning was issued.

Local media footage showed household items scattered across floors, kitchen cabinets thrown open, and merchandise knocked from shelves in several stores. Emergency services also responded to reports of people trapped inside an elevator, while isolated incidents of jammed doors and a tanker truck overturning were reported.

As a precaution, operators temporarily suspended parts of the Shinkansen high-speed rail network for safety inspections before gradually restoring services.

Fire departments in affected areas received multiple emergency calls following the quake, though officials said the overall impact appeared limited compared with previous major earthquakes in the region.

Japan sits on the seismically active Pacific Ring of Fire and experiences thousands of earthquakes every year, making strict building standards and disaster preparedness a key part of the country's infrastructure and emergency response system.
