'''RingCincin OfApi FirePasifik''' atau '''CincinLingkaran Api apiPasifik''' ([[bahasa Inggris]]: ''Ring of Fire'') adalah nasionaldaerah yang uwau sangat sering mengalami [[gempa bumi]] dan letusan [[gunung berapi]] yang mengelilingi cekungan [[Samudra Pasifik]]. Daerah ini berbentuk seperti tapal kuda dan mencakup wilayah sepanjang 40.000 km. Daerah ini juga sering disebut sebagai ''sabuk gempa Pasifik''.
Sekitar 90% dari gempa bumi yang terjadi dan 81% dari gempa bumi terbesar terjadi di sepanjang Cincin Api ini. Daerah gempa berikutnya (5-6% dari seluruh gempa dan 17% dari gempa terbesar) adalah [[sabuk Alpide]] yang membentang dari Jawa ke Sumatra, [[Himalaya]], [[Mediterania]] hingga ke [[Atlantika]]. Berikutnya adalah [[Mid-Atlantic Ridge]].<ref>[http://earthquake.usgs.gov/faq/hist.html#1]</ref><ref>[http://earthquake.usgs.gov/image_glossary/ringoffire.html]</ref>
<!--
The Ring of Fire is a direct consequence of [[plate tectonics]] and the movement and collisions of crustal plates [http://pubs.usgs.gov/publications/text/slabs.html]. The eastern section of the ring is the result of the [[Nazca Plate]] and the [[Cocos Plate]] being [[subduction|subducted]] beneath the westward moving [[South American Plate]]. A portion of the [[Pacific Plate]] bnbvcxxdlmnbfocljmmnzdyudmalongalong with the small [[Juan de Fuca Plate]] are being subducted beneath the [[North American Plate]]. Along the northern portion the northwestward moving Pacific plate is being subducted beneath the [[Aleutian Islands]] arc. Further west the Pacific plate is being subducted along the [[Kamchatka Peninsula|Kamchatka]]—[[Kurile Islands]] arcs on south past [[Japan]]. The southern portion is more complex with a number of smaller tectonic plates in collision with the Pacific plate from the [[Mariana Islands]], the [[Philippines]], [[Bougainville]], [[Tonga]], and [[New Zealand]]. [[Indonesia]] lies between the ''Ring of Fire'' along the northeastern islands adjacent to and including [[New Guinea]] and the ''Alpide belt'' along the south and west from [[Sumatra]], [[Java (island)|Java]], [[Bali]], [[Flores]], and [[Timor]]. The December 2004 earthquake just off the coast of Sumatra was actually a part of the Alpide belt. The famous and very active [[San Andreas Fault]] zone of California is a [[transform fault]] which offsets a portion of the [[East Pacific Rise]] under southwestern [[United States]] and [[Mexico]]. The motion of the fault generates numerous small earthquakes, at multiple times a day, most of which are too small to be felt.
