Ring of Fire

  • Pacific Ring of Fire is a geologically and volcanically active region that stretches from one side of the Pacific to the other.
  • In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements.
  • It has 452 volcanoes (more than 75% of the world’s active and dormant volcanoes). 
  • The Ring of Fire is sometimes called the circum-Pacific belt.
  • About 90%of the world’s earthquakes and 81% of the world’s largest earthquakes occur along the Ring of Fire.
  • The next most seismically active region (5–6% of earthquakes and 17% of the world’s largest earthquakes) is the Alpide belt, which extends from Java to the northern Atlantic Ocean via the Himalayas and southern Europe.
