A powerful magnitude-7.6 earthquake struck off Japan’s northeastern coast on Monday, triggering evacuation orders and a tsunami warning for parts of the coastline.

Some parts of the country experienced tsunami waves, the Japan Meteorological Agency (JMA) reported in an update early Tuesday local time. A 2.3-foot (0.7-meter) tsunami height was observed at Kuji port in Iwate. A 16-inch (40cm) tsunami height was recorded in Aomori and Hokkaido, the JMA said earlier.

After several hours, the JMA downgraded the warning to a tsunami advisory.

The United States Geological Survey (USGS) said the earthquake struck at 11:15 p.m. local time (9:15 a.m. ET) around 44 miles (70km) off the coast of the country and at a depth of around 33 miles.
