A volcano erupted on Japan’s southern island of Kyushu on Friday evening, sending smoke into the sky and lava flowing down the side of the mountain.

There were no immediate reports of injuries in Kagoshima, Kyodo News reported. The eruption of the Sakurajima volcano occurred just before 7 p.m., NHK reported as it broadcast images of the blast.

Kyushu Electric Power Co.’s Sendai nuclear plant, located about 50 kilometers (31 miles) away, is operating normally, a spokesman for the company said by phone, asking not to be named in accordance with its policy.

The Japan Meteorological Agency raised an alert for the volcano from 2 to 3, urging people to stay away from the area. It had increased the warning to 4 last August, the second-highest level, meaning residents should prepare to evacuate. The agency later lowered it.
