Earthquakes. What causes earthquakes? What is a seismograph? Couple facts about the Richter scale and earthquakes. Results after an earthquake. May 1960 – Chile. Magnitude March 1964 – Prince William Sound, Alaska. Magnitude August 1950 – Assam-Tibet. Magnitude Sources.

The earthquake is the sudden movement of the earth's surface. Earthquakes are caused by meteors, volcanic eruptions, underground explosions, collapsing structures. Earthquakes cannot be predicted, although scientists are working on it.

A seismograph is an instrument used for recording the intensity and duration of an earthquake.

Couple facts about the Richter scale and earthquakes.

Each one-point increase on the scale indicates ten times the amount of shaking and 33 times the amount of energy. The energy realeased by a large earthquake may be equal to 10,000 times the energy of the atomic bomb.
