Officials said probability of a magnitude 8 or larger quake was only about 1% but they have urged people to be prepared
Japan has issued a megaquake advisory after a magnitude 7.5 earthquake struck off the eastern coast of Aomori, the northernmost prefecture of Japan’s main island of Honshu.
Damage from the quake was modest – 34 mostly mild injuries and some damage to roads and buildings.
Officials said the advisory announced on Tuesday was not a prediction and the probability of a magnitude 8 or larger quake was only about 1%. But they hope the advisory will make sure the public is prepared in the event of a powerful quake that could have the devastation of the 2011 disaster that killed nearly 20,000 people.
Officials said there was an increased risk of a magnitude-8 or larger quake within the next week and urged residents, especially along coastal areas, to be prepared.
