They call it the Earthquake Alarm System. A report published in Science magazine describes it. Scientists in the United States have developed a computer program that could provide an early warning of major (严重的) earthquakes. The new system is designed to give a warning seconds before an earthquake happens. That may not sound like very long. However, it could give people time to get under a table. The flow of electric power (电流) or gas could be cut. Air traffic controllers could warn away pilots. Even so-called “smart buildings” could be designed to get ready. The system uses a mathematical (数学的) program to measure (测量) information collected by instruments placed across the Los Angeles area. Southern California already has more than 150 stations that measure movements within the ground. The information they collect is sent to a high-speed computer. The new system is designed to estimate (估测) the strength of the earthquake once the shaking starts. Areas directly above the center of the earthquake would have the least warning. Farther places might have as long as forty seconds. Professor Allen notes that an early warning system for earthquakes would require a high quality of public education. Then, another problem is the possibility of false (假的) alarms. ( )1. When an earthquake comes, the new alarm system would give people enough time to ______.
