The Japanese meteorological authorities are assessing a tsunami risk following a major volcano eruption in Indonesia, Japan's media reported on Wednesday. 

Mount Ruang, a stratovolcano in North Sulawesi Province in Indonesia erupted several times overnight Wednesday, forcing hundreds of people to be evacuated after it spewed lava and a column of smoke more than a mile into the sky. 

The volcano first erupted at 9:45 p.m. on Tuesday (1345 GMT) and twice again in the early hours of Wednesday, Indonesia's volcanology and geological agencies said. 

There were no reports of any deaths or injuries but more than 800 people were evacuated from two villages on Ruang island to the nearby island of Tagulandang, state news agency Antara reported.
