Magnitude-7 quake sends tsunami toward Kyushu; Sendai atomic plant checking for damage
A powerful 7.0-magnitude earthquake off Kyushu early Saturday produced small tsunami but no major damage, authorities said.
The U.S. Geological Survey said the epicenter of the shallow quake, which struck at 5:51 a.m., was about 160 km (100 miles) from the town of Makurazaki. Its focus was about 10 km under the ocean floor, according to both the USGS and the Meteorological Agency.
The Meteorological Agency issued a tsunami advisory but cancelled it about 90 minutes later.
A tsunami about 30 cm high was observed on Nakanoshima, but no major damage from either the quake or tsunami was reported, and a pair of reactors at the nuclear power plant in nearby Sendai were unaffected, Kyushu Electric Power Co. said.
We don’t know when bad things will happen.
This time, nothing really horrible happened.
Think and be ready.
… you know.
