JAKARTA - The Center for Volcanology and Geological Hazard Mitigation (PVMBG) reported that there was volcanic activity that occurred on Mount Ibu, North Maluku, in the form of ash ejections as high as approximately 800 meters above the top of the volcano. Mount Ibu Observation Post officer Axl Roeroe said the eruption was recorded on a seismogram at 19:39 WIT with a maximum amplitude of 30 millimeters and a duration of approximately 1 minute 15 seconds. "The ash column was observed to be gray with thick intensity leaning towards the west," he said in a statement received in Jakarta, Antara, Thursday, December 1 evening. Currently, Mount Mother is still at level II or alert since December 10, 2013. PVMBG recommends that people, visitors, or tourists around Mount Ibu not move within a two-kilometer radius and a sectoral expansion of 3.5 kilometers to the crater opening in the north of the active crater of the volcano. "If ash rains, people who are active outside the home are advised to use nose, mouth (mask) and eyes (glasses) protective," said Roeroe. Geologically, the rocks that make up Mount Mother consist of lava, pyroclastic flow, and pyroclastic fall Based on historical records, Mount Ibu first erupted from August to September 1911. However, there was no explanation of the type and impact of the eruption. The next eruption lasted 87 years later, namely December 1998 which resulted in a lava blockage. The next volcanic activity occurred from 2001 to 2004. On April 21, 2008, PVMBG had raised the status of Mount Mother from level II or alert to level III or alert due to seismic activity and the eruption that increased at that time. Mount Ibu is a stratovolcano-type volcano located northwest of Halmahera Island, North Maluku, Indonesia. The top of the mountain is a volcanic crater. The crater center is one kilometer wide and 400 meters deep, while the outer part is 1.2 kilometers wide.
