Lewotobi is a twin volcano located in the southeastern part of the island of Flores, Indonesia. It has two peaks: the Lewotobi Laki-laki (Male Lewotobi) and Lewotobi Perempuan (Female Lewotobi) stratovolcanoes. The more active Lewotobi Laki-laki is about Template:Cvt northwest of the taller Lewotobi Perempuan.

Older forms of its name include Lobetabi,[1] Lovotivo[1] and Loby Toby.[2]

Cultural and Nomenclature Notes

The names Lewotobi Laki-laki and Lewotobi Perempuan reflect local traditions, with the volcanoes regarded as a symbolic pair, often described as "husband and wife." Older names for the complex include Lobetabi, Lovotivo, and Loby Toby.[3]

Geology

Lewotobi's twin peaks are classic stratovolcanoes, formed by successive layers of lava, ash, and volcanic debris. The volcanoes are part of the Lesser Sunda Islands volcanic arc, which is shaped by the subduction of the Indo-Australian Plate beneath the Eurasian Plate. The region is seismically active, with frequent tectonic and volcanic earthquakes.[4][3]

Crater Dimensions

Lewotobi Laki-laki: ~400 m wide

Lewotobi Perempuan: ~700 m wide[3]

Eruptive Material: Primarily andesite[4]

2023

An eruption has been ongoing since 23 December 2023 in Lewotobi Laki-laki, displacing up to 6,500 people as of January 2024.[5]

NASA’s Aqua satellite acquired a true-color image of the November 8, 2024 eruption of Mt. Lewotobi on Flores, Indonesia.

On 4 November 2024, the volcano spewed molten debris at several villages some Template:Cvt away, destroying homes and killing nine people.[6][7] The Centre of Volcanology and Geological Hazard Mitigation recommended that a Template:Cvt radius around the volcano be evacuated.[8] Seven villages were affected by the eruption.[9] A larger eruption occurred on 7 November.[10] On 8 November, the volcano erupted several times, one bearing an ash plume with a height reaching 10 km (6.2 mi).[11] On 9 November, it erupted again, scrambling authorities to evacuate approximately 16,000 people from nearby villages.[12] The eruption caused flight disruptions in Bali and the cancellation of a jazz festival in Labuan Bajo.[13]

2025

On 21 March, Lewotobi Laki-laki erupted, sending ash clouds over Template:Cvt high. Authorities raised the alert to the highest level, and Jetstar canceled some flights to Bali. The eruption followed smaller ones since 13 March. One person was injured during the evacuations, although the details reported were unclear. Bali airport remained open, but seven international flights were canceled. The geological agency warned of lava floods and continued activity.[14][15]

Lewotobi Laki-laki erupted again on 18 May, prompting authorities to raise Indonesia's highest volcanic alert level.[16]

Lewotobi Laki-laki erupted on 17 June, sending ash clouds Template:Cvt high, prompting authorities to raise Indonesia's highest volcanic alert level again, with a plume visible from a distance of 90km to 150km.[17][18][19] Multiple flights were cancelled due to the amount volcanic ash it was releasing into the atmosphere.[20] An area more than 12 square kilometres was incinerated, and 1 person was killed.
