At least four eruptions of Mount Semeru have occurred in Indonesia's East Java province, the Asian nation's Center for Volcanology and Geological Disaster Mitigation announced.
The entity stated that the ash rose to a height of 800 meters above the summit of the volcano, or 4,476 meters above sea level. The eruptions were accompanied by dense emissions of white and gray ash that spread to the south and southwest.
The agency called on residents of the area and tourists not to approach the crater within a radius of 5 km due to the risk of a hot rockslide, and also warned against the danger of lava leakage, the formation of hot clouds and the flow of mud along nearby riverbeds.
