Japanese authorities raised the volcanic alert level for Mt Hakone on Sunday and warned people not to approach the crater, as seismic activity has been increasing in the popular hot-spring resort area near Tokyo.
As the weather agency's alert level was raised to 2 on a 5-point scale for the first time since 2015, some roads were closed and ropeway operations were suspended.
The Japan Meteorological Agency said it decided to raise the level from 1 after the number of volcanic earthquakes increased to 45 on Saturday, compared with zero the previous day. On Sunday, the number reached 48 as of 3 p.m.
The agency warned of a possible eruption and volcanic cinders as fumarolic activity has been intensifying in areas around Owakudani, about 80 kilometers southwest of Tokyo.
