Indonesia's Mount Marapi experienced another eruption on Sunday, emitting smoke and ash into the air, with no reported casualties.

The Marapi Volcano Observation Post in West Sumatra province documented an eruption, producing an ash column approximately 1,300 meters (4,265 feet) high from the peak, followed by ash rain. Ash spewed from the eruption covered roads and vehicles in nearby villages.

Since Friday, over 100 residents have been evacuated following the elevation of the volcano's alert level from Level 2 to Level 3, the second-highest level, on Wednesday.

Marapi is notorious for unpredictable, sudden eruptions, as they are not triggered by deep magma movements that generate seismic tremors. In early December, its eruption sent thick ash columns soaring as high as 3 kilometers (over 9,800 feet), resulting in the tragic death of 24 climbers and injuries to several others during an unexpected weekend eruption.

Approximately 1,400 people reside on Marapi's slopes in Rubai and Gobah Cumantiang, the nearest villages located about 5 to 6 kilometers (3.1 to 3.7 miles) from the summit.

Following an eruption in January of the previous year, which caused no casualties, Marapi has remained active. Indonesia, with over 120 active volcanoes, is susceptible to seismic activity due to its location on the Pacific "Ring of Fire," an arc of volcanoes and fault lines encircling the Pacific Basin.
