The Alert Level remained at Orange. A report on 6 February stated that the dome continued to spread laterally N and S, with N as the dominant growth direction. The rate of rise of the island has slowed down, and the major growth is now lateral by very slow extension of blocky lava lobes and ridges radiating from the central region. The first historical eruption took place in 1718; it and the 1812 eruption produced major explosions. When these data are analyzed and integrated, the geophysical community can look forward to an unusually well-documented account of an episode of explosive island-arc volcanism. . Approximately 7 m of this increase is apparent and not real, i.e., due to the drop in water level between 11-27 February. The maximum depth in this area is 111 feet. Save up to 40% off the cover price when you subscribe to Discover magazine. Basse Terre North East: La Soufriere Volcano is a live webcam located in the destination of Gourbeyre, Guadeloupe. The occurrence of crater tremors was practically zero, with one tremor recorded during the last two weeks. This explosion occurred 52 hours after the last one and was the 30th since the explosive phase started. Nat Hazards, 11: 163-191. This compilation of synonyms and subsidiary features may not be comprehensive. An explosive eruption began at 0840 on 9 April when an ash plume rose to 8 km (27,900 ft) a.s.l. Data from four seismometers are telemetered continuously to Trinidad, and scientists visit the volcano every weekend. More seismographs are being installed and close watch continues. A chemical analysis of the lava collected on 13 December is now available and supports our former identification of a basaltic andesite, with a silica content of 55.3% and an overall composition virtually identical to the numerous basaltic andesite lavas of the Soufrire, which are the products of a quiet outpouring of lava from the crater. On 22 March the western summit of the island was the highest point, 226 feet. of East Anglia. National Emergency Management Organisation (NEMO) reported that activity at Soufrire St. Vincent had been low over the previous few months. The lack of significant seismic activity supports our interpretation of the present events as a relatively quiet eruption of a gas-poor lava. A thermal hotspot in the crater was also detected that day using satellite data by NASA FIRMS. Information Contacts: H. Sigurdsson, Seismic Research Unit, University of the West Indies. The eastern edge of the gas plume reached about 4,700 km to the W coast of Africa by 12 April, and another 2,000 km inland to Mali and Niger on 13 April.

Confirmed Eruption, 2020 BCE 75 years The zone of destruction from the 1902 eruption (N of the Wallibou and Rabacca Rivers) remains partially evacuated. Fiske R S, Shepherd J B, 1982. Ashfalls from most of the explosions were limited to a few centimeters in the N portion of St. Vincent, and small amounts on Barbados, ~150 km E. However, during the 22 April eruption (figure 2) abnormal winds dropped 4 mm of ash on Kingstown (the capital of St. Vincent), on the S end of the island. Depth soundings in the southern part of the Soufriere St. Vincent crater lake, 2 March 1972. Staff members of the Soufrire Monitoring Unit (SMU) made visual observations of the crater on 16 December and reported minor changes in fumarolic activity and a small lake on the E side of the crater floor. A 10-second series of explosions like thunder was heard on 20 November within the crater but the source was not seen because of hot vapor concealing most of the lake. Prime Minister Ralph Gonsalves declared an emergency and called for the evacuation of much of the northern part of the island on April 8 after increasing earthquakes and gas emissions pointed towards something larger brewing. The Alert Level remained at Orange.

Work on the construction of a tiltmeter station at Orange Hill is now completed. The resulting ash plumes rose to 8 km altitude and drifted W. Sulfur dioxide measurements showed an average of 460 tons/day; some SO2 plumes were reported to have reached India. On 8 April UWI-SRC reported an increase in the volume of white gas-and-steam emissions rising from the summit crater and at 0300 scientists at the Belmont Observatory reported episodes of tremor that indicated the movement of magma and fluids near the surface. The Washington VAAC stated that ash plumes during 9-10 April had drifted as far as 1,200 km ESE and about 3,000 km ENE. This is the first time the volcano has erupted since 1979. Debris avalanche deposits offshore St. Vincent (West Indies): impact of flank-collapse events on the morphological evolution of the island. Max VEI: 4, 1979 Apr 13 - 1979 Oct 26 5 days Lahars in the Red and Orange zones were recorded by the seismic network at 0900 and 1000 on 27 April, during and after rainfall. B., Aspinall, W. P., Rowley, K. C., Pereira, J., Sigurdsson, H., Fiske, R. S., Tomblin, J. F., 1979. On 15 September the Alert Level was lowered to Yellow and remaining evacuees were allowed to return home. The water temperature has maintained a level of about 58C for the past week, while the water level continues to decrease at the rate of 6 in/day. Expand each entry for additional details. Sulfur dioxide emissions were measured from a boat near the W coast, yielding a flux of 1,036 tons per day. One rockfall was detected by the seismic network at 0139, and two were noted the next day. These two heights which are now considered reliable are not in agreement with the heights quoted in the previous report when the measuring poles were interfered with by other parties. There were no casualties caused by the eruption. Live Webcam Feed. Anderson T, Flett J S, 1903. Many of the evacuees were. The Grantley Adams International Airport (GAIA) in Barbados also closed. Trees brought down by lahars reached the ocean, where the floating logs created a hazard for small boats along the coastline. The next evening, the NASA aircraft's lidar detected significant quantities of ejecta in the stratosphere, in patches 0.5-3 km thick with a base altitude of about 18.7 km. The La Soufriere volcano in Saint Vincent has erupted, spewing ash and lava in a dramatic event that followed a declaration of disaster in the Caribbean nation. The rates of those events dropped again, at around 0100 on 19 April. These tremors are of shallow depths, very low magnitude and can only be detected by the summit station. No local earthquakes have been recorded by tremors associated with rockfalls on the island continue to occur. Information Contacts: Card 1364 (07 March 1972) John F. Tomblin, Seismic Research Unit, University of the West Indies. The Seismic Research Unit (SRU) collaborates with a small local unit called the Soufrire Monitoring Unit (which operates from the Ministry of Agriculture in Kingstown). Very small-scale maps (such as world maps) are not included. Blocky lava had flowed to the N wall of the crater, reaching maximum dimensions of 725 m across and 110 m high according to their tape and compass survey. of Hawai'i, 2525 Correa Road, Honolulu, HI 96822, USA (URL: http://modis.higp.hawaii.edu/); Sentinel Hub Playground (URL: https://www.sentinel-hub.com/explore/sentinel-playground); Google Earth (URL: https://www.google.com/earth/); Bridie Davies, University of East Anglia, Norwich Research Park, Norwich, Norfolk, NR4 7TJ, UK (URL: https://people.uea.ac.uk/bridie_davies). Analyses showed that the new 2020/21 lava dome was basaltic andesite, similar in composition to the earlier domes (figure 17). "The islands which appeared on 20 November have grown in height and in numbers and they have coalesced to form a continuous land mass in the southeastern part of the lake. The University of the West Indies Seismic Research Centre (UWI-SRC) stated in a press briefing that seismicity at the volcano began to increase in early November and changes in the water lake and fumarolic area were noted on 16 December. Daily satellite-based measurements of SO2 were notable beginning on 9 April. The amount of tephra produced by the current eruption is about two orders of magnitude less than in 1902. . By late October, extrusion of lava into Soufrire's central crater had virtually stopped. We determined very early on that nothing serious was happening, since we have seismic stations both on the volcano and throughout the island [figure 3], none of which had recorded any increased seismicity. After that it grew about 15 m to the NW and SE, according to 11 and 15 February reports (figure 13). Some of the several thousand evacuees work in the area during the day, but most leave at night. Such reports are common for St. Vincent and the entire region. MIROVA (Middle InfraRed Observation of Volcanic Activity) analysis of MODIS satellite data detected a single thermal anomaly during mid-March 2021, followed by a brief break in activity (figure 34). This indicates that the activity has now shifted almost entirely to the N end of the lava island. On 23 March at 1030 the monitoring network recorded a swarm of small low-frequency seismic events that lasted about 45 minutes, which was likely associated with magma movement beneath the dome. It appears that La Soufrire on St. Vincent has taken a decidely more explosive turn. Confirmed Eruption Shepherd J B, 2001. References: Cole P D, Robertson R E A, Fedele L, Scarpati C, 2019. The Soufrire has now been in eruption for over four months and has comfortably exceeded this initial period of high uncertainty. Both the 1979 and 1902 explosive eruption cycles at La Soufrire were quite significant, ranking. As of 19 March the dome was 105 m tall, 921 m long, 243 m wide, and had an estimated volume of 13.13 million cubic meters. On 23 March at 1030 the seismic network recorded a swarm of small low-frequency events that lasted about 45 minutes, possibly associated with magma movement beneath the dome. By the end of May, the new dome had grown to ~500 m in diameter and 60 m in height. By the end of the week both new seismic and continuous GPS monitoring stations had been installed and were transmitting data, bring the total number of dedicated seismic stations to five. The water temperature continues to decrease with minor fluctuations. SRC collected rock samples from the new lava dome and sent them to scientists from the University of East Anglia, University of Plymouth, and University of Oxford on 16 January 2021 as a collaborative project to analyze their composition and compare them with the composition of rocks erupted in 1902, 1971, and 1979. The La Soufrire volcano first erupted on Friday, blanketing the island in a layer of ash and forcing more than 16,000 people to evacuate their homes. Satellite data most recently from 24 April, and seismic data suggested likely cycles of crater dome growth and destruction. Water level is dropping at a slower rate than before 7 March, when the daily drop was 9 inches on the average. "In Card 1336 it was stated by Sigurdsson and Shepherd that 'the new hot lava is significantly more basaltic, i.e., lower in silica (55.3%) than the products of the most violent phases of the 1902 eruption, which were more andesitic in composition, with silica content of 56-58%.' Rockfalls continue to be frequent. The SO2 plume initially fanned out to the NE, E, and SE across the Atlantic Ocean. The VAAC reported that through the day ash plumes rose 12.2-16 km (40,000-52,000 ft) a.s.l. A change in character of an eruption like this is not uncommon. Damage to vegetation was extensive along the W coast, stretching from Larikai Bay to Turner Bay. We and our partners use cookies to Store and/or access information on a device.

St. Vincent suffers power outage after La Soufrire volcano erupts Thanks to the early. The ash plume is mainly being blown to the east from the island towards Barbados and has reached 20,000 feet. The NE rim of the 1.6-km-wide summit crater is cut by a crater (500 m wide and 60 m deep) that formed in 1812. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. However, the rate of extrusion continued to decrease; the late August-late September rate was an order of magnitude less than peak values observed in mid-May. Scientists visited the dome on 16 January and collected rock samples from the W part of the dome. Confirmed Eruption During 15-17 January residents to the W of the volcano reported nighttime crater incandescence. Gas emissions were visible in the afternoon of 17 January rising from the top of the dome as well as from areas of contact between the new and old domes. Lava island stopped growth on 20 March; eruption over, Card 1380 (17 April 1972) Lava island stopped growth on 20 March; eruption over. Observations.

The dome had an estimated volume of 5.93 million cubic meters. This may be a local phenomenon, due to relatively small output of lava into the southern part of the lake in the last few days, and we believe that other inaccessible regions of the lake are hotter.

Additionally, a new GPS monitoring station was placed in Fancy. During an overflight on 26 April scientists observed white steam plumes rising from several locations on the crater floor, though visibility was poor. all webcams provider's website. NEMO reported that the growth rate of the lava dome ranged from 1.9 to 2.13 m3/s (figure 14). The largest of the clouds, from the 17 April explosion, reached an estimated height of 18 km and ultimately grew to a diameter of 140 km. By Robin George Andrews Published April 9, 2021 10 min read The Dust Veil Index for the 1902 eruption of Soufrire was calculated at 300; the Krakatau 1883 eruption = 1,000. Robertson R, 2005. Explosions early on 11 April were followed by widespread power and water outages on the island, as reported by NEMO, and some houses had collapsed due to significant ashfall (figure 24). Catalog number links will open a window with more information. In the period from 8 to 14 December only three events have been positively identified as local earthquakes. En cliquant sur ce bouton, vous acceptez nos. Most of the evidence tends to suggest that there is a slight new lava being extruded at a slower rate into the crater, but whether this decrease in activity is temporary or not is too early to comment on at this stage. Chemical analysis of Soufriere St. Vincent samples from the island in the crater lake collected on 13 December 1971. Much of the northern end of the island was devastated by a major eruption in 1902 that coincided with the catastrophic Mont Pele eruption on Martinique. and drifted mainly ENE. Multiple significant lahars were generated by rainfall during 28-29 April. Crater tremors were of the order one a day since 7 March, but none have been recorded since 1 April.". The water level is now dropping at the rate of 3.5 inches per day leaving on the slopes of the crater a thin scum of muddy substance which on hardening becomes flaky and is eventually washed back into the lake by the rain. Seismic data are transmitted from field sites to the Belmont Observatory (9 km SSW), which is operated by the SMU. The likelihood of dangerously explosive activity during the present eruption is now remote. .

Photos showed people in Sandy Bay shoveling off ash from rooftops on 4 May. Watch volcanoes live and catch an eruption in action! A second explosion at 1445 produced a vigorous ash plume that initially rose to 4 km altitude with lightning visible in the plume (figure 22). Accordingly, SRU did not think it necessary to update their website since it was so insignificant"'a 10 day wonder' as they say in the West Indies, or a 'pseudo-crisis.'" However, the summit and Rabacca station are back in operation, and repairs are continuing on the Wallibou station. No sub-surface earthquakes have been recorded in this period nor have any earthquakes been reported felt. The VAAC stated that a dense ash plume rose to 11 km altitude and drifted E, SE, N, and NE (figure 27). since 1979, although lava has been erupting at the summit since late December 2020. A sample of the new dome collected by John Tomblin in mid-May was described in hand specimen as a basaltic andesite, similar to the 1971 dome. Synonyms of features appear indented below the primary name. At 0300 on 29 April, the seismicity that had accompanied the eruption since 12 April ended almost completely, and there have been virtually no local earthquakes since then. The Alert Level remained at Orange (the second highest level on a four-color scale). No clear volcanic earthquakes have been recorded, although a seismograph 6 km SW of the summit has recently recorded indeterminate signals of 10-60 second duration. Soufrire St. Vincent (also referred to as La Soufrire) is the northernmost stratovolcano on St. Vincent Island in the southern part of the Lesser Antilles. Max VEI: 4, List of 12 Events for Episode 1 at Old summit crater & new NE rim crater, 1784 Mar (in or before) Ash rises into the air as La Soufriere volcano erupts on the eastern Caribbean island of St. Vincent, seen from Chateaubelair, Friday, April 9, 2021. Available webcams . Early on the morning of April 9, the volcano started emitting a tall grey-tan plume of volcanic ash into the air above the small island. A period of tremor at 1649 on 18 April was accompanied by an explosion that sent an ash plume to 8 km altitude and drifted S and SW (figure 30). Thousands flee Caribbean volcano. Consequently, it was impossible to carry out a complete sounding survey. The first pre-eruption seismic event, telemetered to the Seismic Research Unit of the University of the West Indies by seismometers 3 and 9 km from Soufrire's summit, was a strong local earthquake at 1106 on 12 April, within 1 hour of the fortnightly earth tide maximum (calculated by F.J. Mauk). Trees brought down by lahars were swept to the sea; floating logs created hazardous conditions for small boats along the coastline. As strong explosive activity continued at Soufrire St. Vincent, strong SO2 plumes exceeding 2 Dobson Units (DUs) were detected during 9-14 April, moving generally E, based on data from the TROPOMI instrument on the Sentinel-5P satellite. During a field visit on 1 February scientists observed that gas-and-steam continued to rise from the top of the dome as well as along the contact of the old and new domes. Sources: University of the West Indies Seismic Research Centre (UWI-SRC); National Emergency Management Organisation (NEMO), Government of Saint Vincent and the Grenadines; Advanced geospatial Data Management Platform (ADAM); Argyle International Airport Inc. University of the West Indies Seismic Research Centre (UWI-SRC) and National Emergency Management Organisation (NEMO) reported that the explosive eruption at Soufrire St. Vincent (often simply referred to as La Soufriere) continued during 14-20 April, though at a decreasing frequency. Volcanoes of the eastern Caribbean: past activity and future hazards. The pattern of seismicity again changed; high-amplitude tremor episodes ceased, but two low-amplitude and one high-amplitude episode were recorded during 0600-1700. It is evident from the data of the past three weeks that activity in the Soufriere crater is very slight. During the period 13-26 May 1972, the situation at the crater continued along the lines stated in the last report. A third explosive series began at 1835 (figure 23). These earthquakes were more intense and averaged 50/hour; the 23-25 March swarm averaged 1.5/hour. Summary of Soufriere St. Vincent crater observations, 15-31 December 1971. Credit: NOAA. Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. The maximum daily count was 11 events on 16 November. The water temperature at the lake edge, which remained constant between 56-60C during the previous four weeks, dropped to a new low of 53.5C on February 27. Rumors of warm water in the stream S of Windsor Forest village were checked by ground observations on 17 December and found to be untrue. 54m ago distance 2.3 mi. The drop in lake level has accelerated slightly in this period and is now approximately 1 foot 6 inches every 24 hours. Latest nearby quakes. The Washington VAAC reported a new ash emission rising to 7.6 km altitude at 1850 that was associated with a thermal anomaly. As a result, the Volcanic Alert Level (VAL) was raised to Orange (the second highest level on a four-color scale) on 29 December (figure 8). Philosophical Transactions of the Royal Society, London, Ser A, 200: 353-553. https://doi.org/10.1098/rsta.1903.0010, Heath E, Macdonald R, Belkin H, Hawkesworth C, Sigurdsson H, 1998. University of the West Indies Seismic Research Centre (UWI-SRC) and National Emergency Management Organisation (NEMO) reported that the lava dome in Soufrire St. Vincents main crater was an estimated 428 m long, 217 m wide, 80 m high, and had a volume of 4.45 million cubic meters by 27 January. Naples - Mount Vesuv. Volcanic Hazard Atlas of the Lesser Antilles, Trinidad and Tobago, Seismic Res Unit, Univ West Indies, p 240-261. A new swarm of VT earthquakes was detected on 5 April at 0638, the number and magnitude continued to increase until 0830, after which they stabilized. The public was allowed to return to their homes in the Yellow and Orange zones, though access to the Red Zone remained restricted. Sulfur dioxide emissions were also identified in satellite data. Information Contacts: R. Fiske, SI; H. Sigurdsson, Univ. The number of events sharply declined after July but continued intermittently through November 2020. The Alert Level remained at Orange (the second highest level on a four-color scale). The events were located at depths of 6 km, slightly deeper than the swarm events recorded during 22-25 March, located at revised depths of 3-5 km. The Alert Level remained at Orange (the second highest level on a four-color scale). It seems to rise as a continuous mass and there are no disturbances of any sort except for the minor tremors which we have started to record. Clicking on the small images will load the full 300 dpi map. Fiske, R., and Sigurdsson, H. Ash fell across the island, affecting communities including Chateaubelair and Petite Bordel, the observatory, Belmont and surrounding areas at the S end of the island, and forcing the closure of the Argyle International Airport (20 km S). For the first time sulfur dioxide emissions were successfully measured by ground-based instruments; scientists recorded 809 tons per day from a Coast Guard boat along the W coast. Small earthquakes associated with dome growth were recorded on 7 April. An example of data being processed may be a unique identifier stored in a cookie. On 23 April the sulfur dioxide flux was 992 tons per day, recorded again from the W coast. This is the first explosive eruption at La Soufrire since 1979, although lava has been erupting at the summit since late December 2020. Satellite data showed about 0.4 teragrams (Tg) of SO2 in the plume on 10 April, with some stratospheric injection. Fresh, hot material is also visible surrounding the thermal anomaly, which demonstrates the growth of the lava dome over time. La Soufrire, the highest peak on the Caribbean island of St. Vincent, began to explosively erupt Friday morning, forcing thousands to evacuate as ash and smoke filled the sky. La Soufrire is one of the most active volcanoes in the Lesser Antilles and has a long history of eruptions with the historical records showing eruptions in 1718, 1812, 1814, 1902-1903, 1971-72 and 1979. The recent bout of explosive activity began on April 9, 2021. "[SRU] . "During the night of 16 February and most of the day of 17 February there were widespread reports of sulfurous smells throughout southern St. Vincent and as far as the Grenadines. Revegetation of the areas devastated by the 1979 eruption had begun by mid-June. An area of burnt vegetation extended from the dome along the W part of the crater floor. There is some indication that this eruption is similar to what occurred during the 1902 activity at La Soufriere. There have been no deeper or larger earthquakes of the kind which we would expect to see prior to a major increase in the scale of the eruption. . The lake temperature remains between 79-80C at the margin of the lake. The Grantley Adams International Airport (GAIA) in Barbados also closed. Reports are organized chronologically and indexed below by Month/Year (Publication Volume:Number), and include a one-line summary.

Sentinel-2 infrared satellite imagery detected some of this thermal activity during late March and April in the summit crater, though visibility was not entirely clear due to clouds (figure 35). Courtesy of the Seismic Research Unit. Field work during mid-January 2021. Richard Fiske and Haraldur Sigurdsson descended into Soufrire's crater on 18 June. The crater was observed and photographed during 11-12 June; observers saw no signs of lava domes. Powered by www.VolcanoDiscovery.com Lava extrusion continued through August. Card 1330 (15 December 1971) Haraldur Sigurdsson and J.P. Shepherd, Seismic Research Unit, University of the West Indies. A lava dome was emplaced in the summit crater in 1971 during a strictly effusive eruption, forming an island within a lake that filled the crater. Magmagenesis at Soufriere volcano, St Vincent, Lesser Antilles Arc. The only local seismic activity consists of small tremors which continue to originate close to the crater. The gas emissions were most notable from a small depression at the top of the dome.
