The Pacific Ring of Fire is an area in the basin of the Pacific Ocean where many earthquakes and volcanic eruptions occur. It forms a horseshoe shape around the Pacific Ocean basin, and is associated with oceanic trenches. Around 90% of the world's earthquakes and 80% of the largest earthquakes happen along the Ring of Fire. Countries like Chile, Mexico, Japan, the Philippines, and the United States have experienced major volcanic eruptions and earthquakes due to tectonic plate subduction processes along the Ring of Fire.

2. Pacific Ring of Fire
The Pacific Ring of Fire is an area where large numbers of
earthquakes and volcanic eruptions occurs in the bash of the
Pacific Ocean.
In a 40.000km horseshoe shape, it is associated with a nearly
continuous series of oceanic trenches.
About 90% of the world's earthquakes and 80% of the world's
largest earthquakes occur along the Ring of Fire.

3. 1.Chile
Tectonic activity in Chile is related to subduction of the Nazca
Plate to the east.
Chile notably holds the record for the largest earthquake ever
recorded, the 1960 Valdiva earthquake.
In 2008, Chile experienced two volcanic eruptions, the first one
from Llaima Volcano and Chaiten Volcano.

4. 2.Mexico
Volcanoes of Mexico are related to subduction of the Cocos
and Rivera plates to the east, which has produced large
explosive eruptions.
It is said that the 1982 eruption of EI Chichon killed about 2000
people who lived near the volcano.

5. 3.Japan
Ten percent of the world's active volcanoes are found in Japan,
which lies in a zone of extreme crustal instability.
They are formed by subduction of the Pacific Plate and the
Philippine Sea Plate.
Major earthquake occur infrequently.
On March 11, a magnitude 9.0 Earthquake hit Japan, the
county`s biggest ever and the fifth largest on record, according
to US Geological Survey data.

6. Philippine
The 1991 eruption of Mount Pinatubo is the world's second
largest terrestrial eruption of the 20th century.
A devastating eruption occurred in 1911, which claimed more
than a thousand lives.

7. United States
In the westernUnited States lies the Cascade Volcanic Arc.
It includes nearly 20 major volcanoes, among a total of over
4,000 separate volcanic vents including numerous
stratovolcanoes.
The most recent activity in the American portion of the Ring of
Fire occurred in early 2009 when Mount Redoubt in Alaska
became active and finally erupted late in the evening of March
22.

8. Conclusion
The Pacific Ring of Fire area is possible to happen earthquake.
Also Japan often happens earthquake. So these area people
have to be careful about earthquake. And we must measure.
How to evacuate, Where to evacuate, These things are
necessary for us to live in these area.
