The Marapi (Jawi: ماراڤي), or Mount Marapi (,, Jawi: ڬونوواڠ ماراڤي), is a complex volcano in West Sumatra, Indonesia, and is the most active volcano in Sumatra. Like that of its quasi-homonym on Java, its name means "Mountain of Fire". Its elevation is 2885 m. Several cities and towns are situated around the mountain including Bukittinggi, Padang Panjang, and Batusangkar. The volcano is also popular among hikers.

Mythology

According to legend, the mountain is the site first settled by the Minangkabau people after their ship landed on the mountain when it was the size of an egg and surrounded by water. There are large numbers of upright burial stones in the region which are oriented in the direction of the mountain, indicating its cultural significance.

Eruptions

The volcano has a known history of eruptions. Marapi underwent a significant eruption in September 1830. In January 1975 an eruption occurred with mudflows and lahars that caused fatalities in the surrounding area. A significant eruption occurred in 1979, which killed 60 people. At least one person was killed during an eruption in 1996. In April–May 2018 ashfalls to the southeast occurred. Since 2011, the volcano has been at the second level of a four-tier alert system set up by the Volcanological Survey of Indonesia. Predicting the volcano's behavior is described as difficult as the source of its sudden eruptions are shallow and near its peak, while its eruptions are not caused by a deep movement of magma that can be detected as volcanic earthquakes on seismic monitors. Nevertheless, there are about 1,400 people living on its slopes in the villages of Rubai and Gobah Cumantiang, about 5 to 6 kilometers from the summit.

2023 eruption

On 3 December 2023, the volcano erupted, leaving 23 climbers dead. Three people were injured and rescued. The ash reached to a height of 3000 m and fell in nearby regions. A 3 km exclusion zone was announced. On 22 December, the volcano erupted again, emitting volcanic ash that forced the cancellation of flights at Minangkabau International Airport. As of January 2024, at least 113 eruptions have occurred on Marapi since its initial activity in December, with the latest eruption occurring on 23 January. Ash has risen at least 1300 meters into the air and residents within a radius of 4.5 kilometers have been urged to evacuate their homes. At 12:13 a.m. local time on 27 March, Marapi erupted again, emitting a volcanic ash column with a height of 1.5 kilometers. Flights at Minangkabau International Airport were cancelled again due to the eruption.

Lahar flows

On 11 May 2024, heavy rain triggered mudslides and lahar flows from the volcano, killing at least 67 people and leaving 20 others missing.
