A Great Quake Coming

Everyone who lives in San Francisco knows that earthquakes are common in the bay area and they can be devastating. In 1906, for example, a major quake destroyed about 28,000 buildings and killed hundreds, perhaps thousands of people. Residents now wonder when the next "Big One" will strike. It’s bound to happen someday. At least seven active fault (断层) lines run through the San Francisco area. Faults are places where pieces of Earth’s crust (地壳) slide past each other. When these pieces slip, the ground shakes.
To prepare for that day, scientists are using new techniques to reanalyze the 1906 earthquake and predict how bad the damage might be when the next one happens.
One new finding about the 1906 earthquake is that the San Andreas fault split apart faster than scientists had assumed at the time. During small earthquakes, faults rupture. (断裂) at about 2.7 kilometers per second. During bigger quakes, however
