地震学家们在试图预报将袭击加利福尼亚的潜在破坏性地震的地点时,通常总是基于多少使人感到安慰的假定:产生大地震的断层几乎总是一直延伸到地表,在那里地震学家们可以探测和监视它们。加利福尼亚到处都是这种非常明显的断层。包括有名的圣安德烈斯断层在内的大多数断层都属于走滑断层,即在不同方向上移动的地壳板块之间的垂直裂缝。因此不难理解,在1987年10月1日洛杉矶东部6.1级地震(该震造成6人死亡和2亿多美元的损失)发生后,大多数地震学家很快将此归咎于标在地图上的最近的走滑断层,即惠蒂尔断层,它从惠蒂尔郊区向东南延伸约30英
When seismologists are trying to predict the location of potentially devastating earthquakes that will attack California, they are often based on the somewhat comforting assumption that the fault-generating earthquakes almost always extend to the surface, where seismologists They can be probed and monitored. This very obvious fault is everywhere in California. Most of the faults, including the famous San Andreas Fault, belong to strike-slip faults, ie vertical cracks between crustal plates moving in different directions. It is therefore not hard to understand that most seismologists quickly blamed this on the map after the 6.1 magnitude earthquake east of Los Angeles on October 1, 1987, which killed 6 people and caused more than $ 200 million in damage The most recent strike-slip fault, the Whittier fault, extends about 30 yards southeast of the Whittier suburb
