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. The mean diameter of the lava extrusion increased by only 1.5 m between 2 and 25 October, to 870 m, and the maximum height remained ~130 m. Vigorous steaming from the lava was continuing in late October, but the number of small local earthquakes recorded by the summit seismograph had declined markedly since early October. . The VAAC stated that a dense ash plume rose to 11 km altitude and drifted E, SE, N, and NE (figure 27). On 27 December UWI-SRC and NEMO reported that an effusive eruption had begun, which was characterized by a new lava dome in the main crater on the SW perimeter of the 1979 dome (figures 6 and 7). 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. Observations were made during a field visit on 5 January, during a helicopter overflight on 6 January, and based on 9 January drone video. Max VEI: 4, List of 12 Events for Episode 1 at Old summit crater & new NE rim crater, 1784 Mar (in or before) Some of these explosions breach the surface of the lake near the island as areas of boiling water, and are followed by the spread of a red-brown stain which probably consists of stirred-up sediments from the lake bottom. doi:10.1038/282024a0. At night during 15-17 January residents to the W saw incandescence emanating from the crater, a phenomenon likely to be more frequent as the dome grows higher. 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. Activity at the crater has continued along the lines established three months ago. At around 1108 on 22 April explosions produced an ash plume that rose as high as 8 km (26,200 ft) a.s.l. Summary of Soufriere St. Vincent crater observations, 15-31 December 1971. throughout the day. The explosions at La Soufriere were recorded by infrasound (low frequency) on Guadelope, almost 200 miles (300 kilometers) away. Starting at 1653 the network also detected volcano-tectonic (VT) earthquakes, some of which had been felt in communities, including Fancy, Owia, and Sandy Bay.

Information Contacts: Richard Robertson, Seismic Research Unit, The University of the West Indies, St. Augustine, Trinidad (URL: http://www.uwiseismic.com/); Aisha Samuel, Soufriere Monitoring Unit, Ministry of Agriculture, St. Vincent. Scientists visited on 16 January and recorded temperatures of 590C at the dome surface (figure 12). volcano started emitting a tall grey-tan plume, of volcanic ash into the air above the small island. The Soufrire St. Vincent volcano's activity continues at decreasing values since the last explosive eruption on 22 April and all monitoring data indicate the end of the eruptive episode. Nat Hazards, 11: 163-191. Many of the evacuees were moved onto cruise ships to be taken to nearby islands for the time being. 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). . Data from four seismometers are telemetered continuously to Trinidad, and scientists visit the volcano every weekend. Frequent explosive eruptions after about 4,300 years ago produced pyroclastic deposits of the Yellow Tephra Formation, which cover much of the island. 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. Continuous harmonic tremor began to build an hour later, and within 2 hours was saturating the seismometers. There is some indication that this eruption is similar to what occurred during the 1902 activity at La Soufriere. In both Martinique eruptions, dome growth continued for more than two years. Another large explosion was detected at 2300, according to UWI-SRC. Get unlimited access for as low as $1.99/month, The volcanoes of the West Indies have produced some of the. The volcano Alert Level remained at Red. Visual observations and timing of events and processes on the island have permitted correlation of some of the larger tremors with rockfall and lava creep. The dome had an estimated volume of 5.93 million cubic meters. Confirmed Eruption Gas-and-steam plumes were often visible from Belmont Observatory, on Richmond Peak, about 6 km SSW of the crater. First Name. 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 continued to slowly grow during 31 March-6 April, expanding to the N and S. Gas-and-steam continued to rise from the top of the dome, as well as along the contact with the pre-existing 1979 dome. Major mud flows that traveled down the larger valleys (mostly on the W side of the volcano) carved deep, narrow canyons, dramatically exposing pre-1979 valley fill deposits. 15 (Tomblin, 1968). Max VEI: 4, 1979 Apr 13 - 1979 Oct 26 5 days 2020 Dec 27 - 2021 Apr 22 Measurements have been made on near-vertical air photos of the crater taken on 11 February and kindly placed at our disposal by Mrs. M. Barnard. Between 10-20 such events are currently occurring per day. According to data from NEMO, 13,154 people had been displaced by 21 April, with 6,208 people in 85 public shelters and 6,790 people (1,618 families) in private shelters. Photos showed people in Sandy Bay shoveling off ash from rooftops on 4 May. Most of the later explosions were preceded by brief periods (up to 3 hours) of seismic quiet. Forecast models ECMWF, GFS, NAM and NEMS 2022: March During that time the dome grew and expanded to the W, produced small, hot rockfalls, had a blocky appearance, and continued to emit gasses and steam. Additionally, a new GPS monitoring station was placed in Fancy. Remaining gas and steam plumes and lahars will be monitored remotely from its base in Trinidad and Tobago. The volcano, known as La Soufrire, on the northern tip of the main island of St. Vincent, in St. Vincent and the Grenadines, had started showing signs of renewed activity in late December. Satellite data confirmed that explosions had excavated the 2020-2021 lava dome and parts of the 1979 dome, leaving a large crater. worked with Ms. Aisha Samuels, the head of the local volcano monitoring unit, to first investigate the report and later to quell fears that the volcano was doing anything unusual. Earthquake swarms were recorded during 22-25 March and 5 April, signifying a change in the eruption pattern. No lava dome was visible, but a possible spine-like protrusion was seen through the clouds. To convert, we can use a factor of 2. Courtesy of John Tomblin, UWI. The dome dimensions were estimated to be 340 m long, 160 m wide, and 90 m high. A series of powerful explosions from Soufrire produced large ash clouds and several pyroclastic avalanches, forcing the evacuation of more than 17,000 persons from the N end of St. Vincent. The Seismic Research Centre at the University of the West Indies (UWI-SRC) and National Emergency Management Organisation (NEMO) of St. Vincent and the Grenadines reported that during an overflight at 1600 on 31 December scientists confirmed that the new lava dome on the WSW edge of Soufrire St. Vincents 1979 lava dome continued to grow. Scientists visited the dome on 16 January and collected rock samples from the W part of the dome.

Soufrire St. Vincent is monitored by the SRC assisted by the Soufrire Monitoring Unit (SMU) from the Ministry of Agriculture in Kingstown. Sulfur dioxide emissions were again measured from the W coast, yielding a flux of 460 tons per day. Fiske, R., and Sigurdsson, H. The largest avalanche flowed down the Larikai River valley (figure 1) at noon on 14 April and continued beyond the mouth of the river (3 km W of the crater) several kilometers out to sea. The noon explosion on 14 April produced a 100 km-diameter cloud, and two explosions on 13 April also produced sizeable clouds, 60-km-diameter at 1700 and 40 km at 2050. The initial explosion at 0840 showed relatively minor SO2 emissions, though as the day progressed stronger plumes drifted E over the Atlantic Ocean (figure 33). Chemical analysis of Soufriere St. Vincent samples from the island in the crater lake collected on 13 December 1971. The Montserrat Volcano Observatory stated that a sulfur odor and minor ashfall from Soufrire St. Vincent was observed on their island (390 km NNW).

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. 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. | March The Alert Level remained at Orange (the second highest level on a four-color scale). 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). The Alert Level remained at Orange (the second highest level on a four-color scale). This conclusion is supported by the constancy of the rate of lava emission (~0.5 x 106 m3/day) from the beginning of November 1971 to the present, and by the small total volume so far erupted (80 x 106 m3) in comparison with the total fresh lava produced in 1902-03 (2,600 x 106 m3). The Alert Level remained at Orange (the second highest level on a four-color scale). Chairman of the Caribbean Community (CARICOM), Prime Minister Dr. Keith Rowley said Thursday that the regional grouping had mobilized to support St Vincent and the Grenadines. Table 1. Soufrire St. Vincent is monitored by the SRC assisted by the Soufrire Monitoring Unit (SMU) from the Ministry of Agriculture in Kingstown. "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%.' Revegetation of the areas devastated by the 1979 eruption had begun by mid-June.

Another episode of tremor began at 0230 on 15 April, as well as increased ash venting. Additional satellite data. 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. A second period of vigorous ash venting began at 1445 and initially rose about 4 km (13,100 ft) a.s.l. Lava extrusion continued through August. and drifted W. A three-minute period of high-level tremor started at the same time and was flowed by over two hours of lower-level tremor. A large explosion at 0415 on 12 April produced an ash plume that rose to 12.8 km (42,000 ft) a.s.l. Seismicity dropped to low levels after the explosive event and remained at low levels through 27 April; only a few LP, hybrid and VT earthquakes were recorded. Information Contacts: H. Sigurdsson, Seismic Research Unit, University of the West Indies. Compared to the previous drone survey on 12 February, the dome had grown roughly 6.3 million cubic meters. Ash is falling on many communities on northern half of the island. 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.

Table 4 contains mean values for all available wet chemical analyses of Soufrire rocks, summarized from UWI Seismic Research Special Publication No. It is sponsored by the, The IAVCEI Commission on Volcanic Hazards and Risk has a, Middle InfraRed Observation of Volcanic Activity (. The mean diameter of the lava extrusion increased from 820 m on 4 August to 832 m on 21 August, but the highest point has remained at 130 m above the crater floor since 11 August, after 13 m of vertical growth from 10 July to 11 August. As a result, the Volcanic Alert Level (VAL) was raised to Red (the highest level on a four-color scale) at 1830 and the Prime Minister issued an evacuation order for communities in the Red Zone at the N end of the island, affecting 16,000-20,000 people. 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.

A series of Vulcanian explosions that began at 0630 on 13 April, and lasted about 30 minutes, was accompanied by large seismic tremors followed by more than three hours of smaller continuous tremors (figure 26). | June The lake level has been dropping; it dropped a couple of feet in the last three days. On 23 April the sulfur dioxide flux was 992 tons per day, recorded again from the W coast. We are in the lower half of that range. An island 100 m in diameter and 2 m high appeared in the lake center on 20 November. The dome summit was 295 ft. above current lake level on 27 February. Activity during March 2021. Over the past few months, experts have been watching the activity at La Soufrire on St. Vincent closely as, at first, sticky black lava oozed out to form a new lava dome at the volcano's summit. A small lahar signal was recorded at 0740 on 7 May. A third explosive series began at 1835. Lightning was visible in the rising plume. Sulfur dioxide emissions were 232 and 391 tons per day on 17 and 18 April, respectively. 1h 11m ago distance 2.9 mi. The temperature of the water at the crater edge has been decreasing by 0.5C/day on the average since 22-31 March and an increased drop of 3 was detected three days after. Almorales, Seismic Research Unit, University of the West Indies. There is still no sign of deeper seismic activity. April 9, 2021 JPEG. Debris avalanche deposits offshore St. Vincent (West Indies): impact of flank-collapse events on the morphological evolution of the island. These tremors are of shallow depths, very low magnitude and can only be detected by the summit station. The island height is unchanging; loose material on the island is being washed into the lake by the rains, revealing the structure of the lave mass. Persistent steaming from the crater was visible on days when weather permitted views, and thermal anomalies continued to be identified in satellite data. Operator: madinina.webcam Webcam Tartane, Martinique - 63.5 miles from Soufriere: La Caravelle Operator: madinina.webcam 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. Tremors in the vicinity of the crater continue to be recorded, at a rate of about 10/day for the past week. Credit: NOAA, Initial ash plume seen by GEOS-16 from the April 9, 2021 eruption at La Soufriere on St. Vincent. It. . There were no casualties caused by the eruption. 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. The distance from the S shore of the crater lake to the island is approximately 12 m. Table 2. Table 3. By Robin George Andrews Published April 9, 2021 10 min read The highest point on the island is still 226 feet relative to the 3 November datum. Max VEI: 3, 1480 150 years Courtesy of the Seismic Research Unit. Volcanologists monitoring the volcano will need to see if the new magma erupting is more gas rich, and thus more explosive, to try to understand how this eruption might progress. Home; Play. Steam frequently rose slightly above the crater rim. 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. NEMO noted that the total number of displaced people was 22,759 on 15 May though the number continued to fluctuate as people arrived at shelters while others returned home or changed locations. This indicates that the activity has now shifted almost entirely to the N end of the lava island. Almorales, Seismic Research Unit, University of the West Indies. The volcano Alert Level remained at Red. Multiple significant lahars were generated by rainfall during 28-29 April. 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. Sulfur dioxide plumes reached India. Recorded eruptions date back to 1718, with notable eruptions occurring in 1812, 1902, and 1979. Nature, 282 (5734), 2428. During a monitoring visit on 24 January scientists took video and still photos of the dome and installed both a camera and an EDM reflector on the S crater wall. Gas-and-steam continued to rise from the top of the dome as well as along the contact of the old and new domes. Lahar deposits were observed in the Sandy Bay area. Fiske R S, Shepherd J B, 1982. The rate of LP and hybrid events dropped significantly at 2000. J Petr, 39: 1721-1764. https://doi.org/10.1093/petroj/39.10.1721. UWI Seismic Research Centre and National Emergency Management Organisation (NEMO) lowered the Alert Level for Soufrire St. Vincent to Green (the lowest level on a four-color scale) on 16 March, noting that seismic and fumarolic activity were at or below background levels recorded prior to the 2020-2021 eruption. 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. ", Card 1358 (23 February 1972) Crater observations 12-16 February; island growth continues. The VAAC reported that ash plumes rose to 12.2-16 km altitude throughout the day and continued to drift long distances to the ENE, E, and SE. The plume collapsed, generating pyroclastic flows that descended several valleys on S and W flanks, reaching the coast at Morne Ronde (4.3 km W), Larikai (3.5 km WNW), and Trois Loupes Bay (3.5 km NW) (figure 25). respectively. According to a news article, residents of the island of St.Vincent reported smelling sulfur in towns as far S as Kingstown.

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. Closer to the island the water depth starts decreasing at a rapid rate. Resulting pyroclastic flows traveled about 6 km WSW. Gas-and-steam plumes were also visible from Belmont Observatory. The SO2 plume initially fanned out to the NE, E, and SE across the Atlantic Ocean. It is evident from the data of the past three weeks that activity in the Soufriere crater is very slight. University of the West Indies Seismic Research Centre (UWI-SRC) and National Emergency Management Organisation (NEMO) reported that seismicity at Soufrire St. Vincent (often simply referred to as La Soufriere) remained low during 17-24 May, with a few long-period and volcano-tectonic earthquakes occasionally recorded. Some daily earthquakes were recorded during 7-15 June. On 6 May the Volcanic Alert Level was lowered to Orange (the second highest on a four-color scale) because no explosions had been recorded since 22 April and the number of volcanic earthquakes had decreased significantly. Reference. On 11 April 1972, H. Sigurdsson reported that "the Soufriere eruption has now ceased. The rate declined at around 1400 and then significantly dropped at 1600, though small VT events continued to be detected through 1800. Mean values for all available wet chemical analyses of Soufrire St. Vincent rocks, summarized from UWI Seismic Research Special Publication No. Credit: NOAA. The eruption of Soufrire volcano, St Vincent AprilJune 1979. At 0400 on 20 April a lahar was detected by the seismic network and lasted for 30 minutes; it possibly traveled down the SE flank. These are samples of plagioclase-phyric dark gray basaltic andesite with sparse phenocrysts of olivine and pyroxene. . Visual observations from the Belmont Observatory during the early evening showed that the dome height had increased significantly during the day, and incandescent material over the vent area was visible in webcam images (figure 19). It also involved two days of measurements on the summit of the volcano during which scientists were in very close proximity to the vent from which future eruptions will [likely] originate. This decline in seismic activity is probably due to the island not growing or the absence of new lava emitting from the crater. . "From the above it is clear that there is no significant difference in silica content between lava flow and pyroclastic material erupted from the Soufrire Volcano. The main areas of growth are the radial ridges to the N and SE. 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. Trees brought down by lahars reached the ocean, where the floating logs created a hazard for small boats along the coastline.

Source: University of the West Indies Seismic Research Centre (UWI-SRC). The rate of growth was variable, though overall slow. Anomalous winds spread sulfurous odors, causing unwarranted fears. In the period from 8 to 14 December only three events have been positively identified as local earthquakes. Small earthquakes associated with dome growth were recorded on 7 April. At 1135 a band of seismic tremor, associated with an explosion, was recorded, though the emissions were gas-rich and less energetic. Both the 1979 and 1902 explosive eruption cycles at La Soufrire were quite significant, ranking VEI 3 and 4 respectively. Virtually all of the recent expansion of the relatively fluid dome has been lateral rather than vertical. Sentinel-2 thermal satellite imagery detected a thermal anomaly on the SW side of the main crater during clear weather days in January 2021, which represents the active 2020/21 lava dome (figure 16). Green Fig Resort & Spa Upper Palmiste Road Soufriere, St. Lucia. The temperature was 46C on 7 May and 41C on 11 May. Minor rockfalls continue to take place off the edges of the lava mass, but these are less frequent than in the past weeks as is also indicated by a slight decrease in the number of tremors recorded by the summit seismograph stations. 2021: January An explosion produced an ash plume that rose to 8 km (26,200 ft) a.s.l.

Tephra is a lot less dense than dense rock: you get a larger volume out than fits in the hole. Multiple lahars continued to be recorded by the seismic network within all drainages during 28-30 April due to heavy rainfall (figure 32). A swarm of volcano-tectonic (VT) earthquakes began at 0638 on 5 April. As of 2004, the monitoring network had consisted of five seismic stations, eight GPS stations, and several dry tilt sites. Two thermal hotspots were detected using the MODVOLC thermal algorithm on 24 April. The maximum depth in this area is 111 feet. By late October, extrusion of lava into Soufrire's central crater had virtually stopped. This may account for some of the drop in water level.
