A New Way to Help Predict Earthquakes
Scientists in the United States have developed a method that may help to predict earthquakes earlier. They say it could give people who live in deadly earthquake areas enough warning to leave before an earthquake hits.
Currently, the most modem systems for predicting earthquakes find them only a short time before the event. Like most strong earthquakes, the one that hit southwestern China in May wasnot identified early enough for people to flee the area. That earthquake killed sixty-nine thousand people.
But scientists who study earthquakes are reporting that new technology could measure very small changes in the Earth’s surface. Their report was published this month in Nature magazine.
Fenglin Niu is a seismologist with Rice University in Houston, Texas. He and his team performed experiments along California’s San Andreas Fault, an area famous for its many earthquakes.

A. In Parkfield, the scientists noted changes two hours before the secured quakes shuck by the new system.
B. A system providing a signal ten hours before a major quake could help move people from the area and save lives.
C. The changes in air pressure on the Earth’s surface are caused by rocks’ pushing together.
D. It has been confirmed that the deeper the devices can go in the ground, the greater intensity earthquakes can be foun
