IntroductionWe are threatened every day by a menace ofan earthquake and the eruption. It is said thatthere is not the place without an earthquakeand eruption in the world. However, the placewhere an earthquake and eruption occurfrequently in exists.
What is the Pacific Ring of Fire?Pacific Ring of Fire is the area where avolcano and earthquake to be located tosurround the Pacific occur frequently in.Among earthquakes generated all over theworld, 80% are up so far in this area.

Volcanic ActivityThe volcano of this area occupies 75% ofthe world and has interlocking movementlife.ex.Eruption of Mount St.Helens on Julu 22,1980 .
Volcanism & Ｅａｒｔｈｑｕａｋｅ inChileChile experienced two times of eruption in 2008. ● Llaima Volcano ● Chaiten VolcanoChile has relatively a lot the record of the largestearthquake. ● Valdivia earthquake (1960). ● Chile earthquake (2010)
ConclusionRing of Fire is a factor to cause a bigearthquake and eruption tsunami.However, thanks to this activity, I can livewe build the city on land life.
