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.
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.
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.
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.)
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.
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.
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.
