TOKYO — Small tsunami waves hit the northeast coast of Japan after a magnitude-6.9 earthquake early today, weather authorities said, as evacuation orders and alerts were lifted in the region.
Up to 20-centimeter-high tsunami waves hit coastal regions of Iwate prefecture, the Meteorological Agency said.
A 20-centimeter tsunami was observed at the Kuji port, 550 kilometers north of Tokyo, at 9:07 a.m., the agency said.
The quake occurred at 8:06 a.m. with its epicenter off the prefecture at a depth of 10 kilometers, the agency said.
The tremor prompted the agency to issue a tsunami alert, saying a tsunami of up to 1 meter could hit the coastal regions of the prefecture.
With no such waves observed, evacuation orders and instructions as well as the tsunami alert were lifted at 10:20 a.m.
In March 2011, a magnitude-9 quake and tsunami struck the northeast, including Iwate prefecture, leaving about 18,500 dead or missing.
A nuclear plant in Fukushima suffered a triple meltdown after the tsunami swept through the complex.
