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 .
Countries in blue border the Pacific Rim. The Pacific Rim comprises the lands around the rim of the Pacific Ocean. The Pacific Basin includes the Pacific Rim and the islands in the Pacific Ocean. [1] The Pacific Rim roughly overlaps with the geological Pacific Ring of Fire.
For example, the island arc associated with the Aleutian Trench is represented by the long chain of volcanoes that make up the Aleutian Islands. (SVG version of File:Pacific_Ring_of_Fire.png, recreated by Gringer using WDB vector data using code mentioned in File:Worldmap_wdb_combined.svg.)
The Cascade Volcanoes are part of the Pacific Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean. The Cascade Volcanoes have erupted several times in recorded history. Two most recent were Lassen Peak in 1914 to 1921 and a major eruption of Mount St. Helens in 1980.
The fire started about 3:30 p.m. Wednesday near the junction of Road 222 and Road 200. It is one of about a dozen fires across California that have started since Sept. 1
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 ...
