The U.S. government has recently helped people learn more about the dangers of earthquakes by publishing a map. This map shows the chances of an earthquake in each part of the country. The areas of the map where earthquakes are most likely to occur are called earth quake "belts" where government is spending a great deal of money and is working hard to help discover the answer to these two questions;
1. Can we predict earthquakes
2. Can we control earthquakes
To answer the first question, scientists are looking very closely at the most active fault(断层) systems in the country, such as the San Andreas fault in California. A fault is a. break between two sections of the earth’ s surface. These breaks .between sections are the places where earthquakes occur. Scientists look at the faults for changes, which might show that an earthquake was about to occur. But it will probably be many years before we can predict earthquakes
A. They occur at about 4,000 meters below ground level.
B. The injection of water into earthquake faults prevents earthquakes from occurring.
C. They are usually caused by the oil in the faults.
D. Harmful earthquakes can be possibly prevented by causing small, harmless earthquakes.
