Volcanic eruptions have continued on mount Shin-moedake in southwestern Japan since early Wednesday.
The mountain in Kyushu straddles Kagoshima and Miyazaki prefectures.
The Meteorological Agency has raised its alert level to 3 on a scale of 1 to 5, restricting approach to the volcano. It is also advising people to be careful of falling cinders and pyroclastic flows within about 2 kilometers of the crater.
