Figure 8.
Relation between major tectonic plates and
earthquakes. The Earth's surface is made up of 10 major
plates and several smaller plates. Most earthquakes
occur along plate margins. Small dots represent
earthquake epicenters; large dots indicate locations of
volcanoes. An enlargement (bottom) shows tectonic plates
along the Pacific coast of North America. Arrows show
motions of the Pacific and Juan de Fuca plates relative
to North America. (World plate map from "Earthquakes"
