A tsunami warning has been issued following a 7.7 magnitude earthquake off the Japanese coast, prompting mass evacuations. The tremor struck the northeastern part of the country, with the Japan Meteorological Agency cautioning about a potential three-meter tsunami in Iwate prefecture and parts of Hokkaido. This event marks 15 years since a devastating 9.0 magnitude earthquake and tsunami in 2011 that caused significant casualties and displacements. Residents in affected areas have been urged to evacuate to higher ground as precautionary measures are taken. The earthquake, with a magnitude estimated at 5.4, originated off the Sanriku coast at a depth of 10km. Evacuation advisories have been issued to over 128,000 individuals in Iwate and three other northern prefectures. Although initial tsunami alerts were downgraded, coastal areas are still advised to remain vigilant and stay away from potentially hazardous zones. Officials have raised concerns about the possibility of additional seismic events and have emphasized preparedness among residents. The situation is being closely monitored as safety measures are implemented, including thorough inspections at airports and nuclear plants in the affected regions.
