Every approaching year-end in Indonesia, natural disasters often occur in several regions, such as volcanic eruptions. The occurrence of these disasters usually repeats in areas that have experienced similar incidents, such as Mount Marapi in West Sumatra and Anak Krakatau. However, not only that, several other volcanoes in other regions also tend to erupt towards the end of the year. So, what are the factors behind the eruption of volcanoes every year-end? Here is the summary!

Estu added that the cause of volcanoes always erupting at the end of the year can be influenced by several factors, such as high rainfall and a large volume of lava dome. When the lava dome reaches a certain height, it can affect the stability of the mountain slope. A few months ago, Mount Semeru experienced an eruption, and one of the triggering factors was high rainfall and a large volume of lava dome.
