In the Early Jurassic, the supercontinent Pangaea was surrounded by the superocean Panthalassa, the ocean floor of which was composed of the Izanagi, Farallon, and Phoenix plates.These three plates were joined at a migrating, or unstable, ridge-ridge-ridge (RRR) triple junction from which the Pacific Plate began to grow 190 million years ago in an ...
The islands of the Pacific have developed in a number of ways. Some have originated as chains of volcanic islands on the tectonic plates either as a result of mantle plumes or by fracture propagation. Atolls have developed in tropical waters when, after volcanoes sink, coral growth results in reefs as evidenced by the Cook Islands. Coral reefs can ...
Along the rim of the Pacific Basin are convergent plate boundaries often referred to as the andesite line since orogenic andesite is associated with this boundary. This line is often, but erroneously, confused with the boundaries of either the Pacific Plate or the Pacific basin; the andesite line, however, also includes the Juan de Fuca, Cocos, and...
In March and April 2008, a series or swarm of moderate earthquakes occurred both near and within the Blanco Fracture Zone. The swarm began on 30 March when over 600 measurable tremors began occurring north of the zone within the Juan de Fuca Plate. A decade earlier, in January 1998, another swarm was detected at Axial Seamount in the Juan de Fuca R...

The Concise Oxford Dictionary of World Place Names (2017), by John Everett-Heath, states that Oceania is "a collective name for more than 10,000 islands in the Pacific Ocean" and that "it is generally accepted that Indonesia, Japan, the Philippines, Taiwan, and the islands north of Japan (the Kurils and Aleutians) are excluded."
