A strong earthquake struck northern Japan on Sunday evening, prompting authorities to issue a tsunami advisory across coastal regions. The Japan Meteorological Agency reported that the quake, measuring a preliminary magnitude of 6.7, occurred off the coast of Iwate prefecture at a depth of 10 kilometres around 5 p.m. local time.
Following the quake, officials warned of a possible tsunami of up to one metre along northern coastal areas. Public broadcaster NHK advised residents to move away from the shore and avoid low-lying coastal zones. Small tsunami waves of around 10 centimetres were observed at Ofunato city and Ominato port. The advisory remained in effect an hour after the initial tremor, and authorities cautioned that additional aftershocks could follow.
Impact on transport and power
JR East reported delays in bullet train services operating in the region. Kyodo News stated that the tremors had caused temporary power shortages in some areas. However, there were no immediate reports of injuries, structural damage or issues at nearby nuclear power facilities.
Japan sits on the Pacific Ring of Fire, where multiple tectonic plates meet, making it one of the most earthquake-prone countries in the world. The region has experienced devastating seismic events in the past, including the 2011 earthquake and tsunami which caused widespread loss and destruction.
Authorities continue to monitor the situation and are urging residents to remain cautious and follow official safety instructions.
