  3. 3. What is the Pacific Ring of Fire? ● The Pacific Ring of Fire is an area where large numbers of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. ● It is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and plate movements.
  4. 4. Frequency of earthquake● About 90% of the worlds earthquakes and 80% of the worlds largest earthquakes occur along the Ring of Fire.● The next most seismic region is the Alpide belt, which extends from Java to Sumatra through the Himalayas, the Mediterranean, and out into the Atlantic.
  5. 5. Occurrence of an earthquake● There are a lot of hard plates in the earth surface.● They call a fault in one part. Because they move rapidly in mainly the fault, earthquakes happen.● The volcanic activity and the seismic activity are also active.
  6. 6. Past large earthquake 1● 2004.12.26● Sumatra coast earthquake● Magnitude 9.1● About 227898 victims
  7. 7. Past large earthquake 2● 2011. 3.11● East Japan great earthquake● Magnitude 9.0● About 15424 victims or more
