Ring Of Fire
The active volcanoes are located in western Bolivia where they make up the Cordillera Occidentalthe western limit of the Altiplano plateau. Some of the active volcanoes are international mountains shared with Chile. The Central Volcanic Zone is a major late Cenozoic volcanic province. Sabancaya is an active 5,metre 19, ft stratovolcano in the Andes of southern Peruabout km 60 mi northwest of Arequipa. It is the most active volcano in Peru, with an ongoing eruption that started in Ubinas is another active volcano of 5,metre 18, ft in southern Peru; its most recent eruption occurred in Volcanoes in Peru are monitored by the Peruvian Geophysical Institute.
Cotopaxi is a stratovolcano in the Andes, located about 50 km 30 mi south of QuitoEcuadorSouth America. SinceCotopaxi has erupted more than 50 times, resulting in the creation of numerous valleys formed by mudflows around the volcano. In OctoberPichincha Volcano erupted in Quito and covered the city with several inches of ash.
Prior to that, the last major eruptions were in  and inwhen about 30 cm of ash fell on the city. At 5, m 17, ftSangay Volcano is an active stratovolcano in central Ecuador, one of the highest active volcanoes in the world and is one of Ecuador's most active volcanoes. It exhibits mostly strombolian activity; An eruption, which started inended in Geologically, Sangay marks the southern bound of the Northern Volcanic Zoneand its position straddling two major pieces of crust accounts for its high level of activity.
Sangay's roughly ,year history is one of instability; two previous versions of the mountain were destroyed in massive flank collapses, evidence of which still litters its surroundings today. Sangay is one of two active volcanoes located within the namesake Sangay National Parkthe other being Tungurahua to the north. Reventador is an active stratovolcano that lies in the eastern Andes of Ecuador.
Sinceit has erupted over 25 times, with its most recent eruption starting in and, as of [update]still ongoing,  but the largest historical eruption occurred in On March 30,the volcano erupted ash again, which reached a height of about 3 km 2 mi. In Ecuador, EPN monitors volcanic activity. Inthe Santa Maria Volcano erupted violently in Guatemalawith the largest explosions occurring over two days, ejecting an estimated 5. The eruption was one of the largest of the 20th century, only slightly less in magnitude to that of Mount Pinatubo in The eruption had a volcanic explosivity index of 6.
Today, Santiaguito is one of the world's most active volcanoes. Volcanoes of Mexico related to subduction of the Cocos and Rivera plates occur in the Trans-Mexican Volcanic Beltwhich extends km mi from west to east across central-southern Mexico.
It is one of the most active volcanoes in Mexico, having had more than 20 major eruptions since the arrival of the Spanish in Beforethis relatively unknown volcano was heavily forested and of no greater height than adjacent nonvolcanic peaks. This arc includes nearly 20 major volcanoes, among a total of over 4, separate volcanic vents including numerous stratovolcanoes, shield volcanoes, lava domes, and cinder cones, along with a few isolated examples of rarer volcanic forms such as tuyas.
Volcanism in the arc began about 37 million years ago, but most of the present-day Cascade volcanoes are less than 2 million years old, and the highest peaks are less thanyears old.
The arc is formed by the subduction of the Gorda and Juan de Fuca plates at the Cascadia subduction zone. This is a 1,kilometre-long mi faultrunning 80 km 50 mi off the coast of the Pacific Northwest from northern California to Vancouver IslandBritish Columbia. The plates move at a relative rate of over 10 mm 0. Because of the very large fault area, the Cascadia subduction zone can produce very large earthquakes, magnitude 9. When the "locked" zone stores energy for an earthquake, the "transition" zone, although somewhat plastic, can rupture.
Thermal and deformation studies indicate that the locked zone is fully locked for 60 km 37 mi down-dip from the deformation front. Further down-dip, a transition from fully locked to aseismic sliding occurs. Unlike most subduction zones worldwide, no oceanic trench is present along the continental margin in Cascadia. Instead, terranes and the accretionary wedge have been lifted up to form a series of coast ranges and exotic mountains.
A high rate of sedimentation from the outflow of the three major rivers Fraser RiverColumbia Riverand Klamath River which cross the Cascade Range contributes to further obscuring the presence of a trench. However, in common with most other subduction zones, the outer margin is slowly being compressed, similar to a giant spring. When the stored energy is suddenly released by slippage across the fault at irregular intervals, the Cascadia subduction zone can create very large earthquakes such as the magnitude-9 Cascadia earthquake of Geological evidence indicates that great earthquakes may have occurred at least seven times in the last 3, years, suggesting a return time of to years.
Also, evidence of accompanying tsunamis with every earthquake is seen, as the prime reason these earthquakes are Ring Of Fire is through "scars" the tsunamis left on the coast, and through Japanese records tsunami waves can travel across the Pacific. The eruption of Mount St. Helens was the most significant to occur in the contiguous 48 U.
The eruption was preceded by a two-month series of earthquakes and steam-venting episodes caused by an injection of magma at shallow depth below the mountain that created a huge bulge and a fracture system on Mount St. Helens ' north slope. An earthquake at am on May 18,caused the entire weakened north face to slide away, suddenly exposing the partly molten, gas-rich rock in the volcano to lower pressure.
The rock responded by exploding into a very hot mix of pulverized lava and older rock that sped toward Spirit Lake so fast that it quickly passed the avalanching north face. Alaska is known for its seismic and volcanic activity, holding the record for the second-largest earthquake in the world, the Good Friday earthquakeand having more than 50 volcanoes which have erupted since about British Columbia and Yukon are home to a region of volcanoes and volcanic activity in the Pacific Ring of Fire.
Most of these were active during the Pleistocene and Holocene epochs. Although none of Canada's volcanoes are currently erupting, Ring Of Fire volcanoes, volcanic fields, and volcanic centers are considered potentially active. Sinceseismic activity appears to have been associated with some volcanoes in British Columbia including the six subduction-related volcanoes as well as intraplate volcanoes such as Wells Gray-Clearwater volcanic field.
The Northern Cordilleran Volcanic Province is an area of numerous volcanoes, which are caused by continental rifting not subduction; therefore geologists often regard it as a gap in the Pacific Ring of Fire between the Cascade Volcanic Arc further south and Alaska's Aleutian Arc further north. Helens and contains the most explosive young volcanoes in Canada. The eruption styles in the belt range from effusive to explosive, with compositions from basalt to rhyolite.
Morphologically, centers include calderas, cinder cones, stratovolcanoes and small isolated lava masses. Due to repeated continental and alpine glaciations, many of the volcanic deposits in the belt reflect complex interactions between magma composition, topography, and changing ice configurations.
The most recent major catastrophic eruption in the Garibaldi Volcanic Belt was an explosive eruption of the Mount Meager massif about 2, years ago. It was similar to the eruption of Mount St.
Helens,  sending an ash column about 20 km into the stratosphere. The majority of the eruptions in this belt happened either 6—10 million years ago Miocene or 2—3 million years ago Pliocenealthough with some slightly more recent eruptions in the Pleistocene. Eruptions of basaltic to rhyolitic volcanoes and hypabyssal rocks of the Alert Bay Volcanic Belt in northern Vancouver Island are probably linked with the subducted margin flanked by the Explorer and Juan de Fuca Plates at the Cascadia subduction zone.
It appears to have been active during the Pliocene and Pleistocene. However, no Holocene eruptions are known, and volcanic activity in the belt has likely ceased.
The active Queen Charlotte Fault on the west coast of the Haida GwaiiBritish Columbiahas generated three large earthquakes during the 20th century: a magnitude 7 event in ; a magnitude 8. The Public Safety Geo-science Program at the Natural Resources Canada undertakes research to support risk reduction from the effects of space weather, earthquakes, tsunamis, volcanoes, and landslides.
The Kamchatka Peninsula in the Russian Far East is one of the most active volcanic areas in the world, with 20 historically active volcanoes.
Immediately offshore along the Pacific coast of the peninsula runs the 10,metre-deep 34, ft Kuril—Kamchatka Trenchwhere subduction of the Pacific Plate fuels the volcanism. Several types of volcanic activity are present, including stratovolcanoes, shield volcanoes, Hawaiian-style fissure eruptions and geysers. Active, dormant and extinct volcanoes of Kamchatka are in two major volcanic belts. The most recent activity takes place in the eastern belt, starting in the north at the Shiveluch volcanic complex, which lies at the junction of the Aleutian and Kamchatka volcanic arcs.
Just to the south is the Klyuchi volcanic group, comprising the twin Ring Of Fire cones of Kliuchevskoi and Kamenthe volcanic complexes of Tolbachik and Ushkovskyand a number of other large stratovolcanoes. Ichinskythe only active volcano in the central belt, is located farther to the west. Farther south, the eastern belt of stratovolcanoes continues to the southern tip of Kamchatka, continuing onto the Kuril Islandswith their 32 historically active volcanoes. As many as 1, earthquakes are recorded yearly, and magnitudes of 4 to 6 are not uncommon.
Minor tremors occur almost daily in one part of the country or another, causing some slight shaking of buildings. On March 11, a magnitude 9. Mount Bandaione of Japan's most noted volcanoes, rises above Ring Of Fire north shore of Lake Inawashiro.
Mount Bandai is formed of several overlapping stratovolcanoes, the largest of which is O-Bandai, constructed within a horseshoe-shaped caldera that formed about 40, years ago when an earlier volcano collapsed, forming the Okinajima debris avalanchewhich traveled to the southwest and was accompanied by a plinian eruption.
Four major phreatic eruptions have occurred during the past 5, years, two of them in historical time, in and Seen from the Ring Of Fire, Bandai presents a conical profile, but much of the north side of the volcano is missing as a result of the collapse of Ko-Bandai volcano during the eruption, in which a debris avalanche buried several villages and formed several large lakes. In Julythe north flank of Mount Bandai collapsed during an eruption quite similar to the May 18,eruption of Mount St.
After a week of seismic activity, a large earthquake on July 15,was followed by a tremendous noise and a large explosion. Eyewitnesses heard about 15 to 20 additional explosions and observed that the last one was projected almost horizontally to the north. Mount Fuji is Japan's highest and most noted volcano, featuring heavily in Japanese culture and serving as one of the country's most popular landmarks.
The modern postglacial stratovolcano is constructed above a group of overlapping volcanoes, remnants of which form irregularities on Fuji's profile.
Growth of the younger Mount Fuji began with a period of voluminous lava flows from 11, to 8, years ago, accounting for four-fifths of the volume of the younger Mount Fuji. Minor explosive eruptions dominated activity from 8, to 4, years ago, with another period of major lava flows occurring from 4, to 3, years ago.
Subsequently, intermittent major explosive eruptions occurred, with subordinate lava flows and small pyroclastic flows.
Summit eruptions dominated from 3, to 2, years ago, after which flank vents were active. The extensive basaltic lava flows from the summit and some of the more than flank cones and vents blocked drainage against the Tertiary Misaka Mountains on the north side of the volcano, forming the Fuji Five Lakes. The last eruption of this dominantly basaltic volcano in ejected andesitic pumice and formed a large new crater on the east flank. Some minor volcanic activity may occur in the next few years.
The eruption of Mount Pinatubo is the world's second-largest eruption of the 20th century. Successful predictions of the onset of the climactic eruption led to the evacuation of tens of thousands of people from the surrounding areas, saving many lives, but as the surrounding areas were severely damaged by pyroclastic flows, ash deposits, and later, lahars caused by rainwater remobilising earlier volcanic deposits, thousands of houses were destroyed.
Mayon Volcano is the Philippines' most active volcano. The historical eruptions of this basaltic-andesitic volcano date back to and range from Strombolian to basaltic Plinian eruptions. Eruptions occur predominately from the central conduit and have also produced lava flows that travel far down the flanks.
Pyroclastic flows and mudflows have commonly swept down many of the roughly 40 ravines that radiate from the summit and have often devastated populated lowland areas. Taal Volcano has had 33 recorded eruptions since A devastating eruption occurred inwhich claimed more than a thousand lives. The deposits of that eruption consist of a yellowish, fairly decomposed nonjuvenile tephra with a high sulfur content.
The most recent period of activity lasted from toand was characterized by the interaction of magma with the lake water, which produced violent phreatic and phreatomagmatic eruptions.
The volcano was dormant from then showed signs of unrest since with strong seismic activity and ground-fracturing events, as well as the formation of small mud geysers on parts of the island. An eruption occurred in January Kanlaon Volcanothe most active volcano in the central Philippines, has erupted 25 times since Eruptions are typically phreatic explosions of small-to-moderate size that produce minor ash falls near the volcano.
On August 10,Kanlaon erupted without warning, killing 3 persons who were among 24 mountain climbers trapped near the summit. The eastern islands of Indonesia Sulawesi, the Lesser Sunda Islands excluding Bali, Lombok, Sumbawa and SangeangHalmahera, the Banda Islands and the Sangihe Islands are geologically associated with subduction of the Pacific Plate or its related minor plates and, therefore, the eastern islands are often regarded as part of the Ring of Fire.
Although news media, popular science publications and some geologists include the western islands and their notable volcanoes such as KrakatoaMerapiTambora and Toba in the Ring of Fire, geologists often exclude the western islands from the Ring; instead the western islands are often included in the Alpide belt.
New Zealand contains the world's strongest concentration of youthful rhyolitic volcanoes, and voluminous sheets of tuff blanket much of the North Island. Much of the region north of New Zealand's North Island is made up of seamounts and small islands, including 16 submarine volcanoes. In the last 1. In recorded history, major eruptions have been about 50 years apart,  in, and — Minor eruptions are frequent, with at least 60 since Some of the minor eruptions in the s generated small ash falls and lahars that damaged ski fields.
Major eruptions may completely expel the lake water. Where a major eruption has deposited a tephra dam across the lake's outlet, the dam may collapse after the lake has refilled and risen above the level of its normal outlet, the outrush of water causing a large lahar. The most notable lahar caused the Tangiwai disaster on December 24,when people aboard a Wellington to Auckland express train were killed after the lahar destroyed the Tangiwai rail bridge just moments before the train was due.
Inthe ERLAWS system was installed on the mountain to detect such a collapse and alert the relevant authorities. The Auckland volcanic field on the North Island of New Zealand has produced a diverse array of explosive craters, scoria cones, and lava flows.
Currently dormantthe field is likely to erupt again with the next "hundreds to thousands of years", a very short timeframe in geologic terms. The soils of the Pacific Ring of Fire include andosolsalso known as andisolscreated by the weathering of volcanic ash. Andosols contain large proportions of volcanic glass.

A cover of the song by Alan Jackson with guest vocals from Lee Ann Womack was released as a single on December 6, It served as the lead-off single to his 34 Number Ones compilation album, and peaked at 45 in the Hot Country Songsbecoming his first single to miss the top 40 since "Just Put a Ribbon in Your Hair" peaked at 51 in The English power metal band DragonForce recorded a cover as the closing track to the standard edition of their album, Maximum Overload.
Cash's version of "Ring of Fire" was never released as a single in the UK. However, in andit gained significant radio airplay in the UK after it was used in a popular television commercial for Levi's. InLiverpool FC fans began singing the song at matches during the run-up to that year's Champions League Finaland it has been a staple song for the team's fans ever since. Wall of Voodoo's cover version was featured in the avant-garde pornographic film Nightdreams.
