The Pacific is not only the largest ocean but also the world’s oldest and deepest, with an average depth of 4,280 meters (14,040 feet). Most of the geologic activity of the Pacific occurs around its edges. In fact, the so-called Pacific Ring of Fire contains more than 80 percent of the earth’s active volcanoes and most of its earthquake activity.
