The Ring of Fire (also known as the Pacific Ring of Fire, the Rim of Fire, the Girdle of Fire or the Circum-Pacific belt) [note 1] is a tectonic belt of volcanoes and earthquakes. It is about 40,000 km (25,000 mi) long [ 1 ] and up to about 500 km (310 mi) wide, [ 2 ] and surrounds most of the Pacific Ocean .
The Pacific Ring of Fire runs parallel to the line and is the world's foremost belt of explosive volcanism. The term andesite line predates the geologic understanding of plate tectonics . The term was first used in 1912 by New Zealand geologist Patrick Marshall to describe the distinct structural and volcanologic boundary extending from east of ...
The West Coast of the continental United States makes up part of the Pacific Ring of Fire, an area of heavy tectonic and volcanic activity that is the source of 90% of the world's earthquakes. [28] The American Northwest sees the highest concentration of active volcanoes in the United States, in Washington , Oregon and northern California along ...
The Cascades are part of the Pacific Ocean's Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean. All of the eruptions in the contiguous United States over the last 200 years have been from the Cascade Volcanoes. The two most recent were Lassen Peak from 1914 to 1921 and a major eruption of Mount St. Helens in ...

Map of the Garibaldi Volcanic Belt centers. The Garibaldi Volcanic Belt in southwestern British Columbia is the northern extension of the Cascade Volcanic Arc in the United States and contains the most explosive young volcanoes in Canada. Like the rest of the arc, it has its origins in the Cascadia subduction zone.
Australia and New Zealand said they would provide A$42.6 million ($28.05 million) for Pacific Island countries, which span millions of kilometres of ocean, to store humanitarian aid in the region ...
