TheRing of Fire: The Ring of Fire is an area of increased seismic and volcanic activity surrounding the Pacific Ocean. Some of the world's strongest earthquakes and most explosive volcanoes exist in the Ring of Fire. However, many of the Pacific Islands, such as the Aleutian Islands in Alaska and the Hawaiian Islands were formed by volcanic

Of these, around 30 are considered active, meaning that they could potentially erupt at any time. The most active volcanoes in Indonesia are Mount Merapi, Mount Sinabung, and Mount Agung. The volcanoes in Indonesia are spread
