Our Pusdalops team is already in those two locations,” Bambang said.

The statement also mentioned that the Center for Volcanology and Geological Disaster Mitigation (PVMBG) noted the symptoms of increased volcanic activity of Mount Marapi that could cause explosive eruptions already in place since January 2023. Since then, Marapi has been in a status at level II or Alert level because it can erupt at any time.

The PVMBG noted since then there has also been only a slight increase in pressure recorded in the tool near the top/below the crater. Based on the results of a thorough analysis and evaluation until November 16, 2023, the activity level of Gunungapi Marapi is still at Level II with recommendations adjusted to the potential threat of current hazards.

Regarding the level of activity of Mount Marapi at Level II (Alert), BNPB requests that people around Mount Marapi and visitors/tourists do not conduct activities within a 3 km radius of the crater/summit. BNPB also asked that the communities around Mount Marapi not be alarmed by issues about the eruption. The agency asked people to always follow directions from the Local Government.

“In the event of ash rain, people are encouraged to wear masks when leaving the house to reduce the impact of volcanic ash on health. Securing clean water means as well as cleaning the roofs of houses from thick volcanic ash so as not to collapse,” BNPB said in its statement.
