◆Earthquake Information
An earthquake with a magnitude of 7.7 occurred off the coast of Sanriku at 4:52 PM on April 20, 2026 (Reiwa 8).
・As a result of this earthquake, the likelihood of a new large-scale earthquake occurring in the assumed epicenter area of a megathrust earthquake, stretching from off the coast of Nemuro in Hokkaido to off the coast of Sanriku in the Tohoku region, is thought to be relatively higher than normal.
A tsunami warning was briefly issued for the eastern, central, and western Pacific coasts of Hokkaido, but it has now been lifted.
The "Hokkaido/Sanriku Offshore Earthquake Warning" is still in effect.
In the event of a major earthquake in the future, there is a possibility of strong shaking and tsunamis occurring within Hokkaido. Please refer to the Hokkaido website for earthquake preparedness information.
・ Niseko Town recorded an earthquake intensity of 2.
According to Hokkaido Electric Power Company, there has been no impact on their power facilities due to this earthquake.
