Pacific Ring of Fire map: Where is the Ring of Fire?
Mount Sinabung sits in a region known as the Pacific Ring of fire, which forms a chain of volcanic and seismic hotspots.
The Ring of Fire runs along the basin of the Pacific Ocean, covering the west coasts of North and South America and South East Asia.
The majority of the world’s earthquakes and volcanic eruptions occur in these parts of the world.
The Ring of Fire runs for about 25,000 miles (40,000km), along tectonic plate boundaries, ocean trenches and volcanic islands.
