Earthquakes are a phenomenon vibration or shaking of the earth's surface. To adjust to equilibrium conditions. This earthquake can cause damage to the country and disaster housing creature the cause of the earthquake is mainly caused by nature. The earthquake also caused some way by the actions of human beings. But with less intensity that occurs naturally. Geologists estimated that on any given day, about 1,000 earthquakes which are mainly earthquakes are shaking lightly, only people do not feel
the earthquake is a natural phenomenon caused by the movement of tectonic plates. (Vertical lines between the lithosphere), resulting in the shift of a large rock slide or decisive movement and transfer energy. Through the adjacent rock. This energy is in the form of seismic
center earthquakes often occur along faults. In the depths of the earth ever measured in the deep mantle. The point is higher than at the Earth's surface is called the epicenter. The study of earthquakes and seismic waves that are sent out called seismology. Once the epicenter of a massive earthquake off the coast. Tsunamis can be caused by the earthquake may have also caused landslides. And occasionally volcanic activity followed the
earthquake measured using observations from the site a special meter. (seismometer) Section sizes moment is a standard used most worldwide earthquake with a magnitude greater than about 5 for earthquakes, many of them are smaller than 5 magnitude Office of Surveillance earthquakes each country is measured by a standard scale local. most known Richter. The second section has a range similar in numerical accuracy. Earthquake of magnitude 3 or lower, most barely feel or have felt very light. The magnitude 7 quake can cause severe damage to a wide area. Depending on depth Earthquake, the largest in history, with more than nine a little, although no size limit that will be up to much. The last major earthquake was a magnitude 9.0 or greater earthquake magnitude 9.0 in Japan since 2554 and is the largest earthquake ever recorded in Japan. The intensity of the vibrations measured by the Mercalli Intensity Scale was modified. If other variables constant It is a shallow earthquake damage to buildings more earthquake is deeper.
