  1. 1. Pacific Ring of Fire タイトル
  2. 2. What is Pacific Ring of Fire?● Pacific Ring of Fire is a volcanic belt which surrounds whole of Pacific.● Pacific Ring of Fire is area which earthquakes and volcanic eruption frequently occur.● About 80% of the worlds largest earthquakes occur along the Ring of Fire.● Volcanic islands such as Japanese archipelago, Indonesia, Philippines and Aleutian Islands and moutain range such as Andes Mountains and Rocky Mountains are along Pacific Ring of Fire.
  3. 3. Volcanic belt● Volcanic belt is a large volcanically active region.● There is hot magma under ground in volcanic belt.● It is almost similar to volcanic chain. Volcanic chain is Thing which have divided volcanic belt further.
  4. 4. Subduction Zone● Form of volcano belt is caused by plate running against another plate.● 1. When plate runs against another plate, one side sinks in mantle.● 2. The mantle rises and magma rises to the ground.● 3. As a result, volcano belt is formed.
  5. 5. Alpide belt● Alpide belt is a mountain range which extends along Eurasian Continent.● Alpide beltis the second most seismic region in the world.● Volcanic activity doesnt occur so much in are along Alpide belt unlike circum-Pacific orogeny.(Circum-Pacific orogeny is another name for Pacific Fire of Ring.)
  6. 6. Japan● Japan is on Pacific Ring of Fire.● Disadvantage due to the thing ・ Earthquakes frequently occur. ・ Volcanic activity is active and volcano often erupted.● Advantage due to the thing ・ There are a lot of spots of great scenic beauty and hot spring sources. ・ There are a lot of spots where geothermal power generation could conduct.
  7. 7. Volcano in Japan● There are about 130 active volcano.● It is not unnatural that they erupt at any time.● For example, Mount Kirishima is active now and it erupted in this year.● Mount Fuji is the most famous volcano in Japan and the tallest volcano in Japan.● Mount Fuji erupted after about 250 years.● If Mount Fuji erupts, Japan should suffer devastating damage.
  8. 8. Summary● Pacific Ring of Fire is a volcanic belt which surrounds whole of Pacific.● Pacific Ring of Fire is formed by plate running against another plate and one side sinking in mantle.● Japan is on Pacific Ring of Fire, so earthquakes frequently occur.● There are a lot of volcano in Japan.● They may erupt.
