BANYUMAS: Increasing volcanic activity at Mount Slamet in Central Java has prompted authorities to ban climbers from scaling the mountain.
Sudrajat, a staff member at the Mt. Slamet volcanic observation post in Gambuhan, Pulosari, Pemalang, said the volcano, which straddles Central Java's five regencies of Tegal, Brebes, Pemalang, Purbalingga and Banyumas, had continued to rumble from Aug. 4 until Aug. 7.
'Based on observations, Mt. Slamet erupted four times and emitted fireballs from its crater to a height of between 50 and 300 meters from Wednesday evening until Thursday at 12 p.m.,' Sudrajat said as quoted by tribunnews.com on Thursday.
He said the authorities had banned people from being within a 2-kilometer radius of the volcano due to the potential for ash rain.
He also banned residents from celebrating Independence Day on Aug. 17 at the peak of the mountain due to the mounting volcanic activities.
