The volcano, which spat out a cloud of ash hundreds of meters high on Sunday, threatened the surrounding villages, said the Center for Volcanology and Geological Disaster Management. Residents within a five-mile radius of the crater have been advised to leave the area.
In Japan, the eruption triggered a tsunami warning. It applies to the Miyako and Yaeyama island chains in Okinawa Prefecture, the Japanese news agency Kyodo reported.
Exactly one year ago, 34 people died when Semeru erupted. Several villages were then covered in mud and ash. Almost 10,000 residents had to flee their homes.
Indonesia has around 130 active volcanoes. The Southeast Asian island state lies on the so-called Pacific Ring of Fire. There, several tectonic plates collide, so that earthquakes and volcanic eruptions occur particularly frequently.
