The Ibu volcano in Indonesia’s North Maluku province erupted recently, prompting authorities to warn locals and tourists to stay away from the area.
About the Ibu Volcano:
It is a stratovolcano located in the province of Maluku, East Indonesia.
It is one of the most isolated and least accessible volcanoes in Indonesia.
It stands as high as 1,377 metres above sea level.
What is a Stratovolcano?
The stratovolcano is a tall, steep, and cone-shaped type of volcano.
Unlikeflat-shield volcanoes, they have higher peaks.At their peak, stratovolcanoes usually have a small crater. The crater may be filled with water or ice, or it may contain a volcanic dome during a period of relative inactivity.
Stratovolcanoes comprise the largest percentage (~60%) of the Earth's volcanoes, and most are characterised by eruptions of andesite and dacite, lavas that are cooler and more viscous than basalt.
These more viscous lavas allow gas pressures to build up to high levels. Therefore, these volcanoes often suffer explosive eruptions.
They are usually half lava and half pyroclastic material, and the layering of these products gives them their other common name of composite volcanoes.
