Well, gempa yang lumayan besar dirasakan dikota jakarta sore tadi. Iseng2 nyari materi tentang gempa dan antisipasinya. rencana sih mau saya translate, namun daripada bahasanya kacau, mending biar seperti ini aja. 😀
Are You Ready?
One of the most frightening and destructive phenomena of nature is a severe earthquake and its terrible aftereffects. An earthquake is a sudden movement of the earth, caused by the abrupt release of strain that has accumulated over a long time. For hundreds of millions of years, the forces of plate tectonics have shaped the earth, as the huge plates that form the earth’s surface slowly move over, under, and past each other. Sometimes, the movement is gradual. At other times, the plates are locked together, unable to release the accumulating energy. When the accumulated energy grows strong enough, the plates break free. If the earthquake occurs in a populated area, it may cause many deaths and injuries and extensive property damage.
Know the Terms
Familiarize yourself with these terms to help identify an earthquake hazard:
A sudden slipping or movement of a portion of the earth’s crust, accompanied and followed by a series of vibrations.
An earthquake of similar or lesser intensity that follows the main earthquake.
The fracture across which displacement has occurred during an earthquake. The slippage may range from less than an inch to more than 10 yards in a severe earthquake.
The place on the earth’s surface directly above the point on the fault where the earthquake rupture began. Once fault slippage begins, it expands along the fault during the earthquake and can extend hundreds of miles before stopping.
