A 6.9 magnitude earthquake shook northeastern Japan and caused small tsunami waves but no apparent damage, days after a stronger quake in the same region. Friday’s quake occurred off the east coast of Aomori prefecture, in the north of Honshu, the main Japanese island. The Japan Meteorological Agency issued a tsunami advisory that was lifted about two hours later. Small waves were reported in Hokkaido and Aomori prefectures, but no serious damage or injuries were reported. The quake followed a 7.5 magnitude earthquake Monday that caused injuries, light damage and a small tsunami on Japan’s Pacific coast. Authorities had warned of possible aftershocks.

Japan issues tsunami advisory after 6.7 magnitude quake in country's northeast.

Japan is assessing damage and cautioning people of potential aftershocks after a late-night 7.5 magnitude earthquake caused injuries, light damage and a tsunami in Pacific coastal communities. At least 34 people were injured after the 7.5 magnitude quake struck around 11:15 p.m. Monday off the coast of Aomori, the northernmost prefecture of Japan’s main Honshu island. A tsunami more than 2 feet above tide levels was measured in Kuji port in Iwate prefecture before all tsunami advisories were lifted. Power was knocked out for hundreds of homes but was mostly restored Tuesday morning. Authorities warned of possible aftershocks.
