The activity of the Agung volcano on the island of Bali has significantly decreased

Volcanologists say a significant decrease in underground activity in the vicinity of the Agung volcano on the island of Bali, prompting the Indonesian government to lift the state of emergency and allow the population to return to the island.

“The decision to reduce the level of danger was due to the fact that the activity of the volcano has fallen sharply in recent days.The frequency of the tremors in its vicinity, associated with the movement of magma to the surface of the earth, is now about four hundred per day, rather than a thousand a day, as before The radius of the danger zone has decreased from 12 kilometers to 7.5 kilometers, “said Pak Kasbani, head of the State Volcanological Center of Indonesia.

Volcanoes of the Earth today are considered one of the key “conductors” of the climate of our planet. They can both raise the temperature on its surface, throwing huge masses of carbon dioxide and other greenhouse gases and lower it, filling the Earth’s atmosphere with ash particles and aerosol microdroplets, reflecting the rays and heat of the Sun.

Mankind has already experienced several such catastrophes in the short history of its existence. For example, the eruption of the Toba supervolcan, which occurred approximately 70,000 years ago, led to the onset of a “volcanic winter” for several years and the almost complete disappearance of people. Its smaller counterparts, the explosion of the island of Tambor in 1815 and the massive eruption of volcanoes in South America in 530 AD, caused massive famine and outbreaks of plague.

Volcano Agung is one of the largest layered volcanoes in the tropical part of Asia, and it is known to scientists for its infrequent, but very powerful eruptions. The last time Agung “woke up” in 1963, and his eruption led to the death of about a thousand residents of Bali, as well as a series of dramatic climate change.

In September of this year, seismologists recorded a series of earthquakes in the vicinity of the volcano, which became the first serious evidence that he began to wake up, and that his new eruption could occur in the coming months and years. This led to the evacuation of approximately 100,000 people living on the slopes of Agunga, and prompted scientists to begin new projections on the consequences of its eruption.

Reducing the level of danger from “red” to “orange”, as Kasbani notes, does not mean that the eruption will not occur in the coming weeks and months – for this it is necessary to conduct longer observations of the activity of the bowels of Mount Agung. In any case, the authorities of Indonesia advise local residents and tourists not to approach the vents of the volcano and its environs.
