PREFACE Thank God , because of His grace I can finish the task that called the Earthquakes . T his task is proposed in order to fulfill the task of English subjects. I would like to thank all those who helped to make this task can be completed on time. This task is still far from perfect, therefore, criticism and constructive suggestions so I hope to perfect this assignment. Hopefully this task provides information for friends and useful insights for the development and enhancement of knowledge for us all.
PRELIMINARY Earthquakes are natural disasters that frequently occur in the hemisphere. Earthquakes occur due to a shift in the Earth's plates or volcanic eruptions and earthquakes occur when the pressure that occurs because the movement was too large to be arrested .
Tectonic earthquake :
An earthquake is caused by tectonic activity, the tectonic plates shift suddenly has the power of the very small to very large. This earthquake generated a lot of damage or natural disasters on earth, a strong earthquake vibrations can spread into other parts of the earth.
VOLCANIC EARTHQUAKES (VOLCANO )
2. Volcanic earthquakes (Volcano); This earthquake occurred as a result of magma activity, which usually occurs before the volcano erupted. If activeness higher it will cause an explosion that would also lead to the occurrence of earthquakes. The earthquake was only felt around the volcano.
THE CAUSES OF EARTHQUAKES Most earthquakes result from the release of energy generated by the pressure made by the moving plates. The longer the pressure was becoming enlarged and eventually reach the state where the pressure can not be detained again by the edge of the slab. That's when an earthquake will occur. Earthquakes usually happen at plate boundaries such slabs
THE HISTORY OF LARGE EARTHQUAKES IN INDONESIA

Caused at least 1,100 people were killed and thousands trapped in rubble.
EARTHQUAKE • Building collapse • Fire • The fall fatalities • Surface soil into glue and roads to be broken • Landslides caused by shocks • Flooding caused damage to the embankment • The earthquake on the seabed that causes a tsunami
Facing the Earthquake Tips
WHEN INSIDE THE HOUSE • Do not panic and do not run outside, take shelter under a table or bed • If n o, prote ct the head with a pillow or o ther obje ct. • St ay away from bookcases, war drobes a nd window glass. • Berwae of the ceiling might collapse, objects hanging on the wall and so on .
