A 6.1-magnitude earthquake struck Hokkaido in the early hours of Monday, according to the Japan Meteorological Agency. The tremor occurred at 05:24 JST (01:54 IST), with significant shaking reported in the Tokachi region.
Moderate to Strong Tremors Recorded
The earthquake registered a seismic intensity of “5+” on Japan’s scale in central Tokachi, while nearby areas experienced slightly lower intensity levels of “5-”. Authorities have advised residents to remain alert as aftershocks may follow in the coming hours or days.
Despite the intensity, there have been no immediate reports of casualties or major structural damage.
No Tsunami Threat, Officials Confirm
Officials confirmed that no tsunami warning has been issued following the quake. Emergency agencies have urged people in affected regions to stay calm, follow safety protocols, and monitor official updates.
Japan’s disaster response systems were quickly activated, ensuring rapid assessment and communication.
Recent Seismic Activity Raises Concern
The latest earthquake comes shortly after a stronger seismic event on April 20, when a 7.5-magnitude quake hit northern Japan, impacting regions including Aomori Prefecture and Iwate Prefecture.
That earlier quake triggered tsunami warnings, with waves of up to 80 centimetres recorded at Kuji port. It also led to precautionary measures such as suspension of Shinkansen services and evacuation advisories.
Safety Measures and Government Response
Japanese authorities, including Prime Minister Sanae Takaichi, have reiterated the importance of preparedness in earthquake-prone regions.
Key safety advisories include:
Staying away from unstable structures
Keeping emergency kits ready
Moving to safer areas if strong aftershocks occur
Japan remains one of the most seismically active countries in the world, with advanced early warning and disaster management systems helping minimise risks.
