Mount Semeru in Lumajang, East Java, has started spewing hot clouds as far as three kilometers, the Malang Disaster and Mitigation Agency (BPBD) reported on Tuesday, issuing a level II (advisory) warning status for the volcano.
The agency observed that the hot clouds had an amplitude of 23-millimeter, was accompanied by a 540-second earthquake and were headed toward the direction of Besuk Kembar and Besuk Bang deltas.
BPBD Malang head Subagyo said that it was a normal, natural occurrence and that the situation was under control.
However, the Malang agency as well as the Center of Volcanology and Geological Hazards Mitigation (CVGHM) both advise the public to remain at a distance of 1-4 km from the south and southeastern edges of Semeru's active crater.
“We urge the public to remain alert to the potential of hot clouds from Janggring Saloko crater,” National Disaster and Mitigation Agency (BNPB) spokesman Agus Wibowo said on Tuesday.
