The document discusses the locations that experience the largest earthquakes in the world. It lists the top 10 regions which include Alaska, western South America, Indonesia, Japan, the Himalayas, Central America, southern Europe, and the San Francisco and Los Angeles areas. It also explains that convergent plate boundaries produce many of the largest quakes, as they release a lot of built-up stress, such as the recent major earthquake in Japan. The document also covers new techniques scientists are using to better predict earthquakes, such as satellites, infrared radiation, and synthetic aperture radar.
