Authorities are concerned about the possibility of a partial collapse triggering a tsunami similar to the one that struck in 1871.
Volcanic ash has blanketed nearby villages, damaging houses and buildings. Evacuation efforts are underway, with residents being transported by boat to safer areas. Manado City's international airport has been temporarily closed due to ash clouds.
The volcano's activity has escalated since earlier this week, with five major eruptions recorded on April 17. The Volcanology Center has issued its highest alert level, urging people to stay at least six kilometers away from the mountain.
Residents of Tagulandang Island, located east of the volcano, are also at risk and have been ordered to evacuate. The Indonesian disaster agency is coordinating relocation efforts, with Manado serving as a temporary refuge.
The situation remains fluid, and authorities are closely monitoring volcanic activity. (ILKHA)
