East Java Energy and Mineral Resources Agency has issued a warning with regard to increasing volcanic activity of the Semeru mountains, particularly in the Jonggring Seloko caldera.
"We call on residents near Semeru and climbers to increase their cautiousness," agency chief Dewi J Putriatni said in Surabaya on Monday, as quoted by Antara.
The volcanic activity could produce eruptions of volcanic ash and debris, she said.
Authorities have issued a level II warning for the Semeru situation. At least 19 eruptions, producing plumes of white smoke 100-500 meters into the atmosphere, have been recorded in February.
