Mount Ruang : Erupted
Mount Ruang initiated its eruption recently, propelling an ash cloud upwards of a mile into the sky.
- Mount Ruang is a stratovolcano located in Indonesia’s North Sulawesi province. Its summit stands 10,932 feet above sea level, with a caldera that is about two miles wide.
- Stratovolcano is a tall, steep and cone-shaped type of volcano. Unlike flat shield volcanoes, they have higher peaks.
- They are typically found above subduction zones, and they are often part of large volcanically active regions, such as the Ring of Fire that frames much of the Pacific Ocean.
- It comprises the largest percentage (~60%) of the Earth’s individual volcanoes, and most are characterized 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.
