GEOLOGY

Detailed explanation-1: -The Pacific ‘Ring of Fire’ or Pacific rim, or the Circum-Pacific Belt, is an area along the Pacific Ocean that is characterised by active volcanoes and frequent earthquakes. It is home to about 75 per cent of the world’s volcanoes – more than 450 volcanoes. Also, about 90 per cent of the world’s earthquakes occur here.

Detailed explanation-2: -The abundance of volcanoes and earthquakes along the Ring of Fire is caused by the amount of movement of tectonic plates in the area. Along much of the Ring of Fire, plates overlap at convergent boundaries called subduction zones. That is, the plate that is underneath is pushed down, or subducted, by the plate above.

Detailed explanation-3: -The Ring of Fire is a string of volcanoes and sites of seismic activity, or earthquakes, around the edges of the Pacific Ocean. Roughly 90% of all earthquakes occur along the Ring of Fire, and the ring is dotted with 75% of all active volcanoes on Earth.

Detailed explanation-4: -The Ring of Fire is home to 75% of the world’s volcanoes and 90% of its earthquakes. About 1, 500 active volcanoes can be found around the world.

Detailed explanation-5: -The Ring of Fire contains approximately 750–915 volcanoes (about two-thirds of the world’s total) that have been active during the Holocene.
