lascar volcano plate boundary

[36] Geographically, the area of Lascar is located between the Altiplano and the Salar de Atacama[21] 30 kilometres (19mi) farther west;[37] the terrain at Lascar dips in the direction of the Salar. Why do people study Geology? [26] The andesitic-dacitic Aguas Calientes is located 5 kilometres (3.1mi) east of Lascar; it may have formed a lava flow close to the summit during the Holocene. Its rocks have a pale gray-blue colour, and their composition resembles the Soncor flow, despite more mafic lavas and pyroclastics being erupted in the time period between the emplacement of the Soncor flow and the Capricorn Lava. Because the former are. [88] Magma petrology implies that there is another reservoir at 6 kilometres (3.7mi) depth. [219] No lava domes were recorded in the crater during that period. Written By. [53] Around 5150 1250 BCE, as obtained by surface exposure dating,[157] the Tumbres-Talabre lava flow was erupted from the eastern crater. [74], Lascar rocks consist of andesite and dacite. [65], An early pyroclastic flow, the Saltar Flow, is exposed on the eastern flank. [38], Lascar is located in the main volcanic arc, on the western margin of the Altiplano. [164] This eruption was the most significant of the previous two decades,[163] having a VEI of 3. It probably started shrinking in April 1992, although the shrinkage was directly visible only in November. [39], The Tumbres eruption occurred around 7250 BCE,[157] commencing with the eruption of pumice falls that reach thicknesses of less than 1.2 metres (3ft 11in). Lscar Volcano, located in the Chilean Andes 70 km SE of San Pedro de Atacama, is the most active volcano of the Central Volcanic Zone. [135] Possibly, the magma chamber of stage I had almost solidified when the injection of basaltic magma at depths of over 5 kilometres (3.1mi) triggered a remelting. [143] The deposits are formed by a Plinian fallout deposit and an ignimbrite rich in lithics. During earthquakes which type of fault results when one plate is compressed up onto another plate. [83] This origin of Lascar magmas is reflected in the textures of rocks. Volcanoes are most common in these geologically active boundaries. [6][29] Guallatiri, for example, features fumarolic activity that is visible in satellite images. [36], The volcano sits above a major local geological trend, the northsouth Miscanti Line. [45] An area of increased electrical conductivity has been identified beneath Lascar and extends to some neighbouring volcanoes, reaching a depth of over 6 kilometres (3.7mi) south of Lascar. [36] This limestone formation has been identified as the Yacoraite formation. [47] Originally considered part of stage III, it was more recently attributed to stage IV given the considerable (6,000 years) temporal gap between the Tumbres eruption and stage III volcanism, and the geochemistry of the rocks. [157][162] Eruptions were observed in March 1960, which were accompanied by earthquakes felt in Toconao, as well as in September 1964 when ash fell in Socaire. The Saltar flow reached widths of 0.71.3 kilometres (0.430.81mi) and thicknesses of 520 metres (1666ft), increasing to 35 metres (115ft) where the flow entered valleys. This unit, formed during stage II, is known as Piedras Grandes,[53]and is exposed on the western slopes below about 4,900 metres (16,100ft) altitude. [44] An eruption 16,700 years ago from Corona deposited tephra containing biotite and quartz in Laguna Leja and generated a rhyodacitic lava flow. To the left, in the background, the. Data allows to study structural and geomorphological features at the nested craters of Lscar Volcano, Chile. [132] Temperatures have been estimated to be 7401,060C (1,3601,940F) for the andesite and 1,1301,220C (2,0702,230F) for the basaltic andesite. [100] Steam explosions caused by rainfall have been reported. [191] Flow surfaces display pronounced fractures with a V profile,[192] which developed a year after the eruption. [142], Ignimbrite was channeled to the Salar de Atacama by the Quebrada de Chaile, Quebrada de Soncor and Quebrada de Talabre canyons and some smaller valleys, northeastwards by the Quebrada de Morro Blanco and as far as 11 kilometres (6.8mi) southeastwards over the Pampa Leija area. [53] Activity has alternated between the eastern and western part of the volcano during its history. [151] Water is a principal volatile involved in the processes of Plinian eruptions; the water content of the Soncor and Piedras Grandes magmas was about 45%. The deposits left contain both andesite and dacite,[53] with phenocrysts consisting of apatite, augite, biotite, iron-titanium oxides, orthopyroxene and plagioclase in a rhyolite matrix. Estimated temperatures decreased from 800900C (1,4701,650F) at the vent to 580600C (1,0761,112F) farther down the flows. [10] Unlike the neighbouring volcanoes Acamarachi, Licancabur and Quimal, there is no evidence of archeological sites on Lascar,[11] possibly because of the volcanic activity. [63] The formation of the first cone at Lascar may have been facilitated by the intersection between the Miscanti Line and another eastwest lineament[72] formed by PliocenePleistocene tectonic compression of the region,[73] and the lineament would have worked as an ascent path for magma. [57] This eruption was first noticed when ash fell on Salta, and was accompanied by anomalies in the heat emission from the volcano recorded by satellite. [8] Chile Route 23 passes about 10 kilometres (6.2mi) west of Lascar. This sulfur extraction was facilitated by the high oxygen content of the magma, which allowed the formation of sulfur dioxide. [174] The strongest pulse occurred on 20 April between 6:28 and 9:20 and sent flows towards the northwest. [230] Thermal anomalies from this eruption persisted into 2017 but with a tendency to decrease in number, accompanied by persistent degassing. The flow advanced just north of the head of Quebrada Talabre before passing over cliffs and entering it. [23], About 122 volcanoes with Holocene eruptions exist in the Andean Volcanic Belt, including Ojos del Salado which with a height of 6,887 metres (22,595ft) is the highest volcano in the world. [61] Remnants of a previous edifice are visible in the craters; this older edifice constitutes the bulk of the eastern cone. Panorama from the Lascar Southern pyroclastic flow. It features well developed levees and a 10-metre-thick (33ft) flow front. [166], An alternating cycle of fumarolic activity, an accumulation of fumarolic gases in the conduit and lava dome, and explosive activity followed by renewed fumarolic activity have characterized Lascar's activity since 1984. [36] The valleys drain the western, northern and southwestern slopes of Lascar. This pulse generated an eruption column 23 kilometres (14mi) high. [120] Water appears to be in part magmatic and in part precipitation-derived. [154] This debris avalanche is 50 metres (160ft) thick and 25 kilometres (16mi) long. [137] The Manquez agglutinate above the Tumbres deposits was formed either by the Tumbres eruption or by a subsequent stage;[60] a pyroclastic cone in the western crater may be associated with this agglutinate. [31] Larger particles fell closer to the volcano, while smaller particles were carried farther. [59] An eruption commenced at 11:35 local time on 18 April 2006. 1-2 mm of very fine ash fell in Jama (international boundary of Chile and Argentina). [229], Because of the volcano's remote location, much information on its activity comes from remote sensing. [67] The vent was no wider than 2 kilometres (1.2mi), as it is completely hidden beneath the western cone. stratovulcano 5592 m / 18,346 ft. Northern Chile, -23.37S / -67.73W. [3] Other names for the volcano are Hlscar,[4] Hlascar, Ilascar, Kar Las, Laskar, Toconado and Toconao. [100] Trace elements include arsenic, boron and titanium, with smaller amounts of barium, chromium, copper, lead, strontium and zinc. The eruption lasted for two hours and formed a 1011-kilometre-high (6.26.8mi) eruption column. [47] Lava flows from this stage have thicknesses of 2060 metres (66197ft) and lengths reaching 5 kilometres (3.1mi). A major eruption occurred at the Lascar Volcano. [156], Heavy metal exposure is a problem for the region. Stato attuale: normal or dormant (1 di 5) Last update: 3 feb 2022 (Smithsonian / USGS Weekly Volcanic Activity Report) Lscar volcano in northern Chile is the most active of the northern Chilean Andes. Volcanoes at Plate Boundaries - Geology 101 for Lehman College (CUNY) Skip to content Toggle Menu Primary Navigation Home Read Sign in Search in book:Search Book Contents Navigation Contents I. [218] An ash plume was carried 660 kilometres (410mi) east. Grey pumice deposits from the 1993 eruption are visible in the photo above and below. [171], Vulcanian explosions started on 18 April 1993, and on 1920 April 1993, a major eruption occurred. The seismicity was the most notable recorded since the eruption on 10 December. Divergent Plate Boundaries At a divergent boundary, tectonic plates move apart from one another. Lascar is the most active volcano in the central Andes. It is the most active volcano in the region, with records of eruptions going back to 1848. It was emplaced after the collapse of the oldest edifice, covering Aguas Calientes' western slopes. [203], This eruption was the most significant eruption of Lascar in the last 9,000 years, with a volcanic explosivity index of 4[35][129] and a duration of 32 hours,[8] and one of the most significant volcanic eruptions in the recent history of Chile. [146] At the time of emplacement, the ignimbrite was still 200300C (392572F). Dacite has more plagioclase and rhyolite. Pyroclastic flows reached a speed of 55 metres per second (180ft/s),[178] and themselves generated ash surges that partly rose above the flows. [190], There is a pronounced morphology characterized by a channel upslope and snout-like toes downslope. The volcano experienced at least three major eruptions throughout its history: One is the Soncor eruption about 26,450 500 years ago, another in 7,250 BCE and the third in 1993. [54] Six craters are located on the volcano,[29] but sometimes only five craters are counted, in which case the central crater is considered to be the active one. administered through the Department of Geosciences at Oregon State University. [21] The presence of Mesozoic limestone is indicated by xenoliths in Lascar's lavas; the only place they crop out farther east is in Argentina. [89], The oldest volcanic activity at Lascar occurred between 220,000[6] and less than 50,000 years ago. [2], Seismic activity occurs at Lascar. During minor explosive eruptions, eruption columns reach heights of up to 5,000 metres (16,000ft). [182] Hot pyroclastic flows on the southeastern flank covered a surface area of 1318.5 kilometres (8.111.5mi). Volcanic activity is characterized by constant release of volcanic gas and occasional vulcanian eruptions. [128] The towns of Tumbres and Talabre may be affected by pyroclastic flows, and ash falls can occur east of the volcano. Lascar vulcano. [59][97] In December 2002, two fumaroles had temperatures exceeding 295C (563F). However, an eruption of the Cerro Corona lava dome occurred during this period,[60] and activity of stage III did not commence earlier than 22,300 years ago. [228] The last eruption, on 30 October 2015, created a 2,500-metre-high (8,200ft) column of ash that prompted a raise in the local volcano alert level. [157] The 1933 eruption was seen as far away as Chuquicamata. [47] This Plinian deposit reaches thicknesses of 22 metres (72ft) and fell from a 22-to-30-kilometre-high (14 to 19mi) eruption column. [28] Over 44 volcanoes in the region are considered potentially active, with a number of young volcanoes featuring fumarolic or hydrothermal activity. A volcano that is erupting. [116] Otherwise, activity between 1993 and 2000 was not accompanied by deformation of the edifice. the Pacific . [32], Lascar is located in the Antofagasta Region of Chile,[31] and is 5,641 metres (18,507ft),[33][3][34] 5,592 metres (18,346ft),[31][21][15][1] or 5,450 metres (17,880ft) high, according to different sources. Four eruptions occurred at 15:20, 17:22, 19:00 and 21:00 UTC, forming eruption columns reaching altitudes of 10 kilometres (6.2mi). [227], The National Geology and Mining Service of Chile considers Lascar Chile's 14th most dangerous volcano,[237] and in 2020 classified it as a "type I" volcano. At what boundaries do volcanoes form? Lascar volcano Tyra Watts Embed this Flow Large Medium Small Copy Flow URL: https://flowvella.com/s/9hr/Lascar-volcano Volcano: Lascar Country: Chile City: Toconao Continent: South America Presentation By: Kimberly Lema, Jennifer Contreras and Tyra Watts Landforms over this basement include ignimbrites, lava domes, and stratovolcanoes. Large lava flows are visible on its NW flanks. [214] During April 1993, a new lava dome formed in the crater, reaching a diameter of 380 metres (1,250ft). Because Lascar is located in a remote area, it is monitored primarily by remote sensing. Contact of lead scientist: T.R. [137] This edifice is the currently active one, with the deepest of its three summit craters being active. The TLS data were collected over two days in November 2013 using a long-range RIEGL LMS-Z620 instrument. During earthquakes which type of fault results when one plate is compressed up onto . [3] Immediately east of it lies the eastern cone, which is contiguous with the western cone. [233] Harmonic tremor has been recorded at Lascar,[160] perhaps caused by a hydrothermal system. Res. [184] The total area covered by the flows is about 14.2 square kilometres (5.5sqmi) on the northern slopes (Tumbres fan)[185] and 4.3 square kilometres (1.7sqmi) on the southern slopes (Lejia fan). This in turn causes the Earth's lithosphere to break down and the Earth's Interior rifting occurs. Sept. 9, 2022. [145] The ignimbrite features three facies, one rich in breccia, another rich in pumice, and a normal ignimbrite. [77], The rocks of Lascar belong to the calc-alkaline series. [235] The eruptions of April 1993 and September 1986 were both preceded by a reduction of thermal radiation observed by Thematic Mapper. Some guidelines. [36][70] The Miscanti Line dissects the Quaternary basement beneath Lascar,[71] and it may be a hinge of a fold that is being propagated by faults. [72] At least four alignments of volcanoes are recognized in the region. [177], The eruption columns underwent several collapses, creating pyroclastic flows at least seven to nine times. According to SEGEMAR the pyroclastic flows traveled short distances to the N and SE. http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=-23.37%20-67.73&aq=&, http://www.google.com/search?hl=en&biw=1362&bih=600&gbv=2&site=search&tbm=isch&s, http://scholar.google.com/scholar?hl=en&q=L%C3%A1scar%20Volcano&as_allsubj=some&. [139] The Soncor fallout deposit contains a basal gravelly layer and several layers of andesitic and dacitic pumice which also contain lithics. [85] The overall magma supply rate of Lascar is 0.020.03 cubic metres per second (0.711.06cuft/s). 3. By 28 December, the dome had subsided completely in the centre, leaving only its margins. [98] Total flux is estimated to be 1,31218,469 kilograms per second (2,89040,720lb/s),[87] and occurs even between eruptions. The equilibrium line at Lascar was at an altitude of 4,7004,800 metres (15,40015,700ft) during the last glacial maximum. Maintaining our website and our free apps does require, however, considerable time and resources. [44] The end of glaciation may have accompanied an increase in volcanic activity, a phenomenon that has been noted at other volcanoes. Trenches mark subduction zones. The importance of the multidisciplinary approach. [169] This cycle ended after 1993, probably because the April 1993 eruption modified the conditions in the volcanic system. Get started for FREE Continue. [95], A number of xenoliths occur in Lascar's rocks; a large amount of the phenocrysts are ultimately derived from them. [91], Lascar emits plumes of gas and white clouds of condensed water vapor,[29] mostly over many hundreds of fumarolic vents, which are chiefly located in the active crater. [224] During the following days, additional explosions generated columns up to 3 kilometres (1.9mi) high, with little ash production. On 17 December 1993, another explosion created an eruption column 810 kilometres (5.06.2mi) high. Learn. [201] Over 0.1 millimetres (0.0039in) of ash fell over a surface area of over 850,000 square kilometres (330,000sqmi). Data available through GEOFON. Lascar is located close to the Atacama Desert, one of the world's driest deserts. [16] A number of supervolcanoes exist in the Central Volcanic Zone, they are part of the Altiplano-Puna volcanic complex. [95] Later deposits include the Cenozoic sedimentary Quepe strata. [57] Recorded eruptions occurred in 1858, 1875, 18831885, 18981900(?) See the station distribution here and the data availability here. [27] Given the low population density around many of these volcanoes, there is often little information on their activity. [187] The speed of these flows has been estimated at 100700 kilometres per hour (62435mph). [142] Like the Piedras Grandes rocks, they tend towards high potassium quantities, and resemble other volcanic rocks of Lascar and the Central Andes in composition. On December 9 small amounts of fine ash were emitted from fumaroles and the next day the activity was back to normal levels with only gas and steam emitted. Bunch grass and shrubs grow on the volcano's slopes. [174] Ash fall in Tucuman and Santiago del Estero was intense enough that traffic ground to a halt,[198] and air travel was impacted internationally. [132], Lava flows less than 50 metres (160ft) thick issued from the stage I cone and reached lengths of 16 kilometres (9.9mi). Unmanned aerial vehicles,[236] occasional reconnaissance flights and infrequent visits to the volcano are also used. The white mushroom eruptive column rose 4000-5000 m high over the summit. [153] Such a vent or caldera is substantially smaller than the volume of rocks erupted, a discrepancy that is also evident in the 1932 eruption of Quizapu. The fumaroles also release carbon monoxide, hydrogen, hydrogen chloride, hydrogen sulfide, and smaller amounts of helium. On the western slope, it buries the even older Piedras Grandes flow, which crops out only at the margins of the Soncor flow. [86] After the end of stage I, a period of glacial erosion occurred prior to new activity,[72] which created furrows in the Saltar flow. . It was accompanied by a Plinian fall deposit. [72], Hydrogen chloride and hydrogen fluoride are also released in large amounts, with estimates made in 20032004 indicating a mass flux of 340,000,000 kilograms per year (11kg/s) and 150,000,000 kilograms per year (4.8kg/s) respectively. On the southeastern flank, the pyroclastic flows formed a fan extending several hundred metres into Pampa Leija. [242] In 1982,[243] the town of Talabre was moved for safety reasons[52] stemming from flooding and volcanic activity,[243] and ballistic blocks ejected by the volcano are a threat to mountaineers and scientists working on Lascar. [193] The pyroclastic flow surfaces subsided after the eruption, with pulses of faster subsidence coinciding with the 1995 Antofagasta earthquake and the 2007 Tocopilla earthquake. SERNAGEOMIN reported that an eruption at Lscar began at 1236 on 10 December with an explosive event that produced a dense ash plume and pyroclastic flows proximal to the crater. 92 views 3 minutes ago In Chile, the Lascar volcano unexpectedly erupted on December 10th, sending a plume of ash more than 6,000 meters or 19,700 feet above what was already one of the world's. These ignimbrites form a 3 steep slope in the area. [45] Noticeable erosion occurred in the areas over which pyroclastic flows had passed, forming abrasion surfaces and removing loose detritus from the ground. This way, topographic details can be scanned over large areas with great precision and in relatively little time. A volcano in the Andes in Chile's north rumbled to life early Saturday, triggering minor earth tremors and sending a plume of smoke and ash 6,000 meters (nearly 20,000 feet) into a clear sky.. [199] Tephra fall from this eruption was recorded in Argentina, including in Buenos Aires, 1,500 kilometres (930mi) away, and in Brazil, Paraguay, and Uruguay. [54] Exposures of the basement are often delimited by faults. Lascar has had a number of small to moderate explosive eruptions in historic times, as well as a few larger eruptions that caused ashfall hundreds of kilometers away. [40] MioceneQuaternary volcanic centres in the neighbourhood include Cerro Negro in the north, Acamarachi northeast, Tumisa southwest, and the Cordon de Puntas Negras in the south,[41] which Lascar is sometimes considered to be part of. Lascar is an andesitic-to-dacitic stratovolcano with 3 overlapping summit craters. Large lava flows are visible on its NW flanks. The southeastern slopes drain into Laguna Leja[9] which is close to the volcano,[48] and the northwestern slope drains through the Quebrada de Morro Blanco. Flashcards. The flow deposit was later modified by glacial activity. [6] The present-day snowline in the region lies at an altitude of 6,050 metres (19,850ft), higher than the summit of Lascar. [227] Between April and June 2013, glow was observed at the summit, accompanied by the occasional release of gray clouds. What type of plate boundary is creating lascar volcano? Learn. [35] At least ten different pulses were observed, generating columns of various heights[173] and forming mushroom clouds. [79] The magmas are contaminated by the local crust, but not to the extent found in the Galan or Purico complex eruption products. A new western edifice was constructed on top of the Soncor vent, during the Holocene activity then shifted again to the eastern edifice and continues there to this day. There are traces of a collapse of the volcano towards the northeast, with an associated horseshoe-shaped scar. Afterwards, up to four different units of pyroclastic flows, each 110 metres (3.332.8ft) thick, formed deposits up to 10 kilometres (6.2mi) long. [144], The magma erupted was generated in a magma chamber starting from andesite, which underwent complex petrogenetic processes. What plate is forming lascar volcano? [130] The long-term magma supply rate of Lascar is about 0.08 cubic kilometres per millennium (80,000m3/a),[131] the volcano has produced about 3040 cubic kilometres (7.29.6cumi) of rock. [66] While the Piedras Grandes flow was formed by a glacier run that transported blocks with sizes of up to 8 metres (26ft), Soncor was formed by a large eruption. [47] The composition of the Piedras Grandes unit is andesite containing amphibole, basaltic andesite and hornblende. [81], Magma erupted by Lascar appears to form from the mixing of mafic and more evolved magmas; the 1993 eruption deposits contain bands of different rocks. [50] These domes cover a surface area of about 90 square kilometres (35sqmi). [250], Temperatures in the surrounding region range between 25 and 40C (13 and 104F). Regulatory limits on concentrations of other elements in water were also exceeded, although only temporarily. [252] Other reports claim that flamingos remained; other animals like donkeys and llamas were seen around the volcano one day after its eruption.[209]. [168] The temperatures of the lava dome can reach 148367C (298693F). Another explosion at 13:02 sent a column 8.5 kilometres (5.3mi) high. [222] The 18 April eruption was seen from the El Abra copper mine 220 kilometres (140mi) away and resulted in ash fall north-northeast from the volcano. The Cascade volcanoes in the northwestern United States and the volcanoes in Mexico and Central America are related to the subduction under the North American Plate of the small Juan de Fuca and Cocos plates, which are on the east side of the Pacific Plate. The name originates from the Atacameo word lskar or lassi (English: tongue), thought to refer to the shape of the volcano. [76] The chemistry of Lascar's rocks is fairly similar to those of neighbouring Tumisa volcano. [36], Lascar is a steep volcano[7] formed by two irregularly shaped truncated cones that extend eastwest,[52][53] on a trend that includes Aguas Calientes. Two types of Plate boundaries are often associated with volcanic eruptions: Plates rip apart at a divergent plate boundary, causing volcanic activity and shallow earthquakes; and At a convergent plate boundary, one plate dives or "subducts" beneath the other, resulting in a variety of earthquakes and a line of volcanoes on the overriding plate. In 1985, a 150-by-150-metre (490ft 490ft) hot spot in this crater was observed in satellite images. [14], Volcanoes in the Andes occur in four separate regions: the Northern Volcanic Zone between 2N and 5S, the Central Volcanic Zone between 16S and 28S, the Southern Volcanic Zone between 33S and 46S,[15] and the Austral Volcanic Zone, south of the Southern Volcanic Zone. Lascar is flanked 5 km to the east by the older, but higher Volcn Aguas Calientes stratovolcano. This information was summarized from the GVP/USGS Weekly Volcanic Activity Report. The volcanic complex experienced several major, up to VEI 6, pre-historic eruptions but no calderas were formed. [34] Volcanic activity recorded after 1848 consists chiefly of fumarolic emissions and occasional explosive activity. [157][53] This flow extends 8 kilometres (5.0mi) northwest and is 2030 metres (6698ft) thick. [239] Past eruptions caused ash fall in Argentina and disruption of air travel[241] and could have major effects in the Salta Province in case of renewed activity. Lascar Volcano Volcanic Ash Advisory: ISOLATED PUFF AT 1545 to 27000 ft (8200 m) Thu, 3 Feb 2022, 00:26 Lascar (Chile) - Smithsonian / USGS Weekly Volcanic Activity Report for 26 January-1 February 2022 (NEW) SERNAGEOMIN reported minor increases in surficial activity at Lscar. Other minerals include anhydrite,[57] augite, plagioclase[33] which is also the dominant phenocryst phase in Lascar rocks,[76] apatite, ilmenite, magnetite, olivine, orthopyroxene, phyrrotite, quartz, rhyolite in the groundmass, and spinel in inclusions. [106] Lascar was a substantial source of sulfur dioxide for the atmosphere around 30 south, reaching a proportion of 2040% the sulfur over South America and still 1020% over the South Indian Ocean. How to watch volcanoes? [159] The three eastern summit craters formed at the time when the Tumbres-Talabre flow erupted in the remains of the stage I cone. [141] The Plinian deposit has a colour ranging from white to creamy. [183] The southern flank flows at first proceeded along a gully before spreading out.
