Earthquake
Earthquake is one of the most destroying
natural disasters. Unluckily it often happens in several regions. Recently a horrible
earthquake has shaken West Sumatra. It has brought great damages. Why
did it occur? Do you know how an earthquake happens?
Earthquakes are usually caused when
rock underground suddenly breaks along a fault. This sudden release of
energy causes the seismic waves. It make the ground shake. When two
blocks of rock or two plates are rubbing against each other, they stick a
little. They don’t just slide smoothly. The rocks are still pushing against
each other, but not make. After a while, the rocks break because of all the
pressure that’s built up. When the rocks break, the earthquake occurs.
During the earthquake and afterward,
the plates or blocks of rock start moving, and they continue to
move until they get stuck again. The spot underground where the rock
breaks is called the focus of the earthquake. The place right
above the focus is called the epicenter of the earthquake.
