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] Mount Ibu sits within the Pacific Ocean's " Ring of Fire" that has 127 active volcanoes. [2]
In August 2009, the Volcanological Survey of Indonesia raised the eruption alert level for Ibu to Orange/III. [3]
In 2023, a total of 21,100 eruptions were recorded from the volcano, making it the second most active volcano in Indonesia. [4]
On 16 May 2024, the Volcanological Survey of Indonesia raised its highest alert level (Red/IV) for Mount Ibu following another series of eruptions. [5] As a result, seven villages were evacuated. [6]
On 1 June 2024, Mount Ibu erupted at 11:03 WIT (02:03 GMT) for 265 seconds, producing a five kilometer (3 mile) high ash plume that dispersed towards the southwest. [7] [8] and deposited ash on the village of Gam Ici, where many evacuees displaced by previous eruptions had been relocated. [9] The Volcanological Survey of Indonesia warned of a potential for flash flooding and lahar flow in the region, and recommended that people move at least seven kilometers (~4.35 miles) away from the crater. [7]
On 6 June 2024, Mount Ibu erupted three more times, producing ash clouds as tall as 1,200 meters (4,000 feet). [10]
