TEMPO.CO, Jakarta - Head of Geology Agency Rudy Suhendar said that Mount Anak Krakatau still poses two threats; eruption and its effects in the form of rockslide materials.
As satellite images suggest, a 64-hectare section of the mountain had vanished and is strongly believed to be the cause of the tsunami that hit the coastline in Banten and Lampung on Saturday, December 22.
“We are worried of yet another rockslide,” said Rudy on Thursday, December 27.
The Volcanology and Geological Disaster Mitigation Center (PVMBG) is actively monitoring the mountain located at the Sunda Strait while the geological agency has increased its status from Level II to Level III based on its continuous eruptions that happened lately and the magma that directly flows into the ocean.
There are also threats of slight volcanic ash from Anak Krakatau that has showered over areas in the vicinity of Anyer and Cilegon.
Rudy explained that the visible change of Anak Krakatau is its crater that has increased in size based on satellite images from December 19 compared to the taken on December 23.
