The 7.8 magnitude quake that ravaged part of Ecuador's Pacific coast on April 16 injured about 12,500 people and more than 650 people lost their lives. The power of that earthquake is a stark reminder of the dangers in the U.S. posed by the San Andreas Fault and others … in fact, scientists are continually predicting when the “Big One” will hit.
A fault is a fracture or zone of fractures between two blocks of rock, which enables the blocks to move in relationship to one another. When the movement is rapid, this can lead to an earthquake. While the 800-mile San Andreas Fault is infamous, there are others in the U.S. that have caused earthquakes and present ongoing risks, albeit not as massive as the huge California fault. Faults come in all sizes – from small ones with short fault lines you can see in a single road cut – to huge faults with lines only clearly visualized from orbiting satellites. Faults exist on every continent and were formed at different periods during the Earth's long history.
