When the United States Geological Survey makes its annual report on earthquakes, California usually leads the nation in the number of tremors that people, rather than measuring instruments, can “feel”. California also suffered the most serious damage from an earthquake in the Survey’s
1983 report on significant earthquakes.  These are the quakes that measure at least 6.5 on the Richer scale. These earthquakes are included if they cause considerable damage or casualties ( that is, if people are injured or killed).
    In 1983, four significant quakes occurred in the United States.  This compares to 70 earthquakes worldwide. The strongest Unites States earthquake took place in south-central Idaho and measured 7.3. It killed two children in Challis, a nearby town. It caused ＄2.5 million in damages. A 6.5 quake in Coalinga, California, injured 45 people and cost ＄ 3.1 million, Large areas of Coalinga had to be razed or torn down because the buildings could net be repaired.
    A tremor off the southern coast of Alaska in the Pacific Ocean measured 6.5 but caused no damage. However, a 6. 6 quake on The Big Island in Hawaii hurt six people and cost＄6 million.
    California had a total of 119 earthquakes that people felt and reported to authorities in 1983. Hawaii was second with 75, and Alaska was third with 64 earthquakes.
