Overview● Introductory● The Ring of Fire and Earthquake● Details (1)● Details (2)● Serious Earthquake in The Ring of Fire● conclusion
Introductory● The Pacific Ring of Fire is the area that aggregate the part of the area that is easy to occur eruptions.● The Ring of Fire has about 450 volcanoes.
The Ring of Fire and Earthquake● Most of worlds earthquake occur along the Ring of Fire.● The second most seismic area is the Alpide belt.● The third is the The Mid-Atlantic Ridge.
Details (1) ● The Ring of Fire is direct result of plate tectonics, the movement and collisions of lithospheric plates. ● The eastern section of the Ring of Fire is the result of the Nazca Plate and the Cocos Plate being subducted beneath the westward moving South American Plate. ● The Cocos Plate is being subducted beneath the Caribbean Plate in Central America.
Details (2) ● A portion of the Pacific Plate along with the small Juan de Fuca Plate are being subducted beneath the North American Plate. ● Along the northern portion the northwestward moving Pacific plate is being subducted beneath the Aleutian Islands arc. ● More west the Pacific plate is being subducted along the Kamchatka Peninsula arcs on south past Japan.
Serious Earthquake in The Ring of FireThere were three large earthquakes during the 20th century. ● Magnitude 7 earthquake in 1929 ● Magnitude 8.1 earthquake in 1949 ● Magnitude 7.4 earthquake in 1970
ConclusionBecause the Ring of Fire have potential of occurring seriousearthquake, we have to watch for along the Ring of Fire always.By studying the motion of eruption in the Ring of Fire, we willbe able to do provision when serious eruption occur suddenly.
