Local authorities have called on residents living nearby Mount Raung in East Java to stay alert despite a decline in the volcano’s activity shortly after its alert status was upgraded. On Monday, the Volcanology and Geological Hazard Mitigation Center (PVMBG) raised Mt. Raung’s alert status from Level 2 to Level 3 after it discharged molten lava and spewed volcanic ashes on Sunday and Monday. Wednesday, activity at the 3,332-meter volcano, located on the border between Jember, Bondowoso and Banyuwangi regencies, had been reportedly decreasing although its alert status remained at Level 3.
Bondowoso BPBD operational head Kukuh Triyatmoko, meanwhile, said volcanic ash, carried by winds in the direction of Bondowoso on Tuesday and Wednesday, was not as thick as that seen on Monday. The affected districts, Jember and Banyuwangi, have six subdistricts respectively within an zone of a radius of 3 kilometers wide approximately around the volcano crater.
The Mt. Raung had already erupted in February, but the volcanic materials have not crossed the crater rim. In preparation, the head of East Java BPBD, Sudarmawan, said that 33 points of evacuation were in place in the three regencies in anticipation of an eruption of Raung. Seismographic data from the Songgong District observation post showed widths of vibration between 17 and 22 millimeters in the last days. The authorities of Air Navigation also warned the flights to and from Surabaya, the capital of the province, and Denpasar, Bali, in order to avoid flying over Mt. Raung.
