Mount Ibu (Indonesian: Gunung Ibu) is a stratovolcano at the north-west coast of Halmahera island, Indonesia. The summit is truncated and contains nested craters. The inner crater is 1 km (0.62 mi) wide and 400 m (1,312 ft) deep, while the outer is 1.2 km (0.75 mi) wide. A large parasitic cone is at the north-east of the summit and a smaller one at the south-west. The latter feeds a lava flow down the west flank. A group of maars are on the western and northern side of the volcano.[1]
In August 2009 Volcanological Survey of Indonesia raised the eruption alert level for Ibu to Orange/III.[2]
In 2023, a total of 21,100 eruptions were recorded from the volcano, making it the second most active volcano in Indonesia.[3]
On 16 May 2024, Indonesian volcanologists raised their highest alert level (Red/IV) for Mount Ibu following another series of eruptions.[4] As a result, seven villages were evacuated.[5]
