The Gunung Marapi Volcano Post (PGA) reported that the volcano located in Agam Regency and Tanah Datar Regency, West Sumatra Province (West Sumatra) erupted again at 11.50 WIB with a maximum amplitude of 30.4 millimeters.

"The eruption at 11.50 WIB was recorded on a seismogram with a maximum amplitude of 30.4 millimeters and lasted about 49 seconds," said PGA Gunung Marapi officer Teguh Purnomo in Padang, Antara, Wednesday, September 17.

In its report, PGA cannot record the height of the volcanic ash column because it is covered in clouds.

Currently, the volcano as high as 2,891 meters above sea level (MDPL) is Level II or Alert. This means that people are prohibited from doing activities within a three-kilometer radius of the activity center (Verbeek Luxury).

In addition, the Center for Volcanology and Geological Hazard Mitigation (PVMBG) also warns of a potential threat of cold lava, especially for people living along rivers that originate from the top of the volcano.

This condition is especially during rain or rainy season. Then, in the event of ash rain, people are advised to use a nose and mouth covering mask to avoid respiratory tract problems.

PGA also reminded that piles of materials caused by volcanic eruptions can cause water flows that at any time have the potential to cause cold lava floods.

This condition cannot be ignored because it is very vulnerable and dangerous, especially when it rains with high intensity. The most likely thing is cold lava floods such as the May 11, 2024 incident which claimed dozens of lives.
