A sudden hydrothermal eruption occurred at the Sileri Crater, part of the Dieng Plateau Volcanic Complex, in central Java Island, on July 2, 2017 at 12:00 local / 5:00 UTC.
According to Sutopo Purwo Nugroho of the BNPB, 17 people were close to the crater during the eruption, which propelled hot water and mud to about fifty meters in height. Ten people, who were within 15 meters of the crater were injured, and taken to the Batur Public Health Center for treatment.
Local residents and visitors were asked to evacuate the area, and a 100-meter-radius area prohibited around the crater enforced ... but will it be respected?
Although the level of activity is considered normal for the Dieng plateau, the VSI recommends that activities not near the craters should not be carried out because of the toxic gases (CO2 and H2S).

Update: A rescue helicopter crashed by going to help evacuate the residents, killing the eight people on board.
The helicopter crashed about three minutes before arriving at the Dieng Plateau. The plane allegedly struck a cliff on Butak Mountain in Temanggung District, Central Java Province.
Sileri is one of the most active craters on the ten craters of the Dieng plateau, a region much appreciated by tourists because of its mild temperature and the presence of Hindu temples dating back to the 9th century.
The last eruption of the Sileri dates back to September 27, 2009, with an expulsion of materials at 200 meters in height. The deposits reached 10 cm. Near the vent and 1 cm. At the farthest point. A major incident in 1979 caused the asphyxiation of 140 people following an emission of toxic gas by the near Sinila crater.
