It has been since last week, precisely since Tuesday, that the volcano located on the Indonesian island of Bali was expelling volcanic ash, however, the ascent of the magma now indicates that a much larger eruption is to arrive.
It was about two months ago that Mount Agung has had some seismic activity records, and last week the volcano erupted, eventually expelling volcanic ash about 4 km high. It is now believed that an even larger eruption may be eminent, that is, seismic activity has increased and magma is actually rising. The alert level has been launched and is at its maximum, and authorities have already determined an exclusion zone within a radius of 8 to 10 km of the volcano, which must be evacuated and maintained until there is no danger.
So far, about 40,000 people have been evacuated from the area, yet Indonesian officials say about 100,000 have yet to evacuate, and the number could rise to 150,000 depending on the outcome of this seismic activity. 445 flights have been canceled this Monday, leaving about 59,000 people withheld, Ngurah Rai international airport spokesman Air Ahsanurrohim said in a statement.
There are already photos that already reveal a red glow originating in the volcano, resulting from the intense heat. This also means that the magma is getting closer and closer to the surface. Once that happens, it will descend the mountain with unexpected consequences.
Authorities also warned of the danger of Lahares, a type of mud avalanches made up of materials from the volcano, as well as water. This flow of volcanic mud can take two forms, or more liquid or even as cement. In addition to mud, the lahars carry a lot of debris as the volcano moves downwards, such as large stones and tree trunks. The flows can still move at very fast speeds and thus lead to an increase in the level of river waters.
The last great eruption of Mount Agung occurred in 1963 and lasted about a year. More than 1,000 people have been killed and only since then are measures taken to control the activity of the volcano in Indonesia, a region that has more than 140 active volcanoes.
