Official alert on delayed seismic activity concludes, but government warns risk remains
NHK reports the national government states the possibility of large-scale earthquakes has not disappeared despite the conclusion of the vigilance phase.
The official call for vigilance regarding delayed earthquakes in the Hokkaido and Sanriku offshore region has concluded, marking the end of the alert period established following a major seismic event in the area. This development signals the cessation of the specific warning phase known as the Hokkaido and Sanriku offshore delayed earthquake attention information.
Despite the conclusion of this designated alert period, the national government has reiterated that the possibility of large-scale earthquakes has not disappeared. Officials maintain that the end of the vigilance phase does not equate to the removal of risk, cautioning that seismic activity remains a potential threat.
In light of this ongoing uncertainty, authorities are urging the public to continue preparing for seismic activity. The government's stance suggests that while the formal window of heightened alert has closed, the underlying geological risks persist without a defined timeline for when activity might return to normal levels.
Experts have weighed in on the situation, reinforcing the government's position by noting that seismic activity remains active. They recommend the continuation of preparedness measures to ensure public safety, aligning with the official directive to remain vigilant even after the formal call for vigilance has ended.
The decision to terminate the alert period follows the issuance of the warning in response to the significant earthquake that struck the region. However, the specific criteria used to determine the end of the alert versus the ongoing assessment of risk are not detailed in the current reports from the national government.
As the alert period officially ended on 27 April 2026, the focus has shifted from immediate warning to sustained readiness. The national government's message remains clear: the cessation of the specific information broadcast does not signal a return to safety, and citizens must continue to maintain their preparedness for potential future events.
