Earthquakes: Movement of the Earth’s Crust
Earthquakes are the shaking and moving of the ground when energy is released in waves. These
waves are called seismic waves. These waves are similar to ocean waves, which move through
water. Seismic waves, however, move through the ground. Most earthquakes are caused by the
movement of large sections of the Earth’s crust, called plates. The place where two plates meet
is called a fault. Faults look like large cracks in the ground. If the two plates move in different
directions, they build up energy at the fault line. When enough energy builds up, the stress on the
fault becomes too great and it ruptures. This releases the energy and the
ground starts to shake.
Earthquakes can also be caused by other natural events, such as landslides and volcanoes. Man-
made earthquakes happen because of nuclear testing and mining explosions. The first movement
of an earthquake, called the main shock, is often followed by smaller ground trembles, called
aftershocks. These aftershocks are the plates settling into their new position. Aftershocks can
continue for days after the main shock. There are an estimated 500,000 earthquakes around the
world each year. Most are so mild they are only recorded on scientific instruments. Only about
100,000 can be felt by humans. Of these, only about 19 a year cause major damage.
Major earthquakes in populated areas can cause huge destruction. Buildings collapse, roads and
bridges buckle and crack, and electrical and gas lines break and cause fires. If the earthquake
happens in the ocean, it makes a series of huge ocean waves called a tsunami. The tsunami
travels until it finally reaches land, where it causes large flooding. Scientists are searching for
ways to predict earthquakes. They study the historical patterns of earthquakes and monitor the
movement of the plates with seismic equipment. While they cannot predict an exact date of a
future earthquake, they have a better understanding of when earthquakes are more likely to
happen.
