The Pacific Rim consists of the vast amount of land encircling or contained within the Pacific Ocean/Oceania/Australasia, numbering at least forty countries. A few notable territories are Australia, New Zealand, China, Japan, Russia, United States, Canada, the Koreas, Vietnam, Thailand, Indonesia, Peru, Costa Rica, Mexico…and so on.
Interestingly the Pacific Rim runs practically alongside the Ring of Fire for much of its circumference and that means trouble. The Ring of Fire describes a chain of geologically unstable formations where volcanoes and earthquakes like to express themselves dramatically on a regular basis. In fact 75% of the world’s volcanoes squat along this rim.
