Card 1394 (22 May 1972) Water temperature and level decrease. 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. A team of volcanologists and seismologists from the Seismic Research Unit arrived on St. Vincent 13 April, and were later joined by researchers from several other institutions. Manizales - Nevado d.

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). These tremors are of shallow depths, very low magnitude and can only be detected by the summit station. 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. Satellite data confirmed that explosions had excavated the 2020-2021 lava dome and parts of the 1979 dome, leaving a large crater. 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 under the significant ashfall. All available evidence indicates that the eruption will neither end nor become violent in the early future. Lahar deposits were reported in the Sandy Bay area. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. University of the West Indies Seismic Research Centre (UWI-SRC) and National Emergency Management Organisation (NEMO) reported that the effusive eruption at Soufrire St. Vincent (often simply referred to as La Soufriere) became explosive on 9 April after a period of increased seismicity, gas emission, and rapid dome growth. These are not felt; they are instrumental, that is, recorded. Water level is dropping at a slower rate than before 7 March, when the daily drop was 9 inches on the average. Ashfall continued to be widespread on 10 April; deposit thickness varied from less than 1 mm in Colonaire (12.5 km SSE) to 10-15 mm in Rabacca (7.4 km SSE). The. Between 10-20 such events are currently occurring per day. During the August survey, some pulsing steam emission took place, mostly at the S edge of the lava, but no explosions were observed. 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.'" | September Scientists visited the dome on 16 January and collected rock samples from the W part of the dome. The maps database originated over 30 years ago, but was only recently updated and connected to our main database. The eruption of 1979 was characterized by ashfall, pyroclastic flows, and lahars, in addition to a series of Vulcanian explosions during 13-26 April 1979 that destroyed the lava dome in the summit crater, which had formed during a 1971 effusive eruption (SEAN 04:04). At around 1108 on 22 April explosions produced an ash plume that rose as high as 8 km (26,200 ft) a.s.l. Sign up for our email newsletter for the latest science news, GEOS-16 false color loop showing the eruption of La Soufriere on St. Vincent. 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. The maximum water depth recorded was 99.5 ft, at a point approximately halfway between the island and the lake edge. Seismic data are transmitted from field sites to the Belmont Observatory (9 km SSW), which is operated by the SMU (figure 4). Pyroclastic flows overnight were channeled to the E into the Rabacca River drainage. Gas-and-steam continued to rise from the top of the dome as well as along the contact of the old and new domes. The resulting ash plumes rose to 10.6-16 km altitude throughout the day. . On 11 April 1972, H. Sigurdsson reported that "the Soufriere eruption has now ceased. La Soufrire on the island of St. Vincent, which last erupted in 1979, has a long and tragic history of powerful but mercurial blasts. Steam from the dome was visible from Belmont Observatory through 4 January. Occasional satellite images of the summit showed a series of changes to the new crater, centered in the SW part of the summit crater. A small lahar signal was recorded at 0740 on 7 May.

The recent bout of explosive activity began on April 9, 2021. The island is now 145 feet in height above water level, but its growth has decelerated in the last few days. At 1400 the rate of the earthquakes started to decline and then significantly dropped at 1600, though small VT events continued through 1800. Anomalous winds spread sulfurous odors, causing unwarranted fears. 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. Island now 145 feet above water level; lake temperature drops, Card 1341 (11 January 1972) Island now 145 feet above water level; lake temperature drops. 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, 1814 Jan 9 - 1814 Jan 9 The April explosions deposited a total of about 30 cm of ash on the zone within 1 km of the crater rim. The activity pattern of the eruption was comparable to that of the event that occurred in . The dome summit was 295 ft. above current lake level on 27 February. Powered by www.VolcanoDiscovery.com Periods of tremor and near-constant LP and hybrid earthquake swarms continued on 16 April. The greatest heights on the eastern and northern summits are 196 and 211 feet, respectively. An episode of tremor that began at 1135 was associated with increased explosive activity, though the emissions were gas rich and less energetic than previous events. Restrictions remain in effect for the 4,000 persons who live in the zone devastated by the 1902 eruption, N of the Rabacca and Wallibou Rivers. These minor explosions accompanied by rockfalls are the most likely source of the numerous minor tremors which are recorded by the seismographs close to the summit. Card 1358 (23 February 1972) W. Aspinall and H.J. MIROVA (Middle InfraRed Observation of Volcanic Activity) analysis of MODIS satellite data shows the beginning of thermal activity in late December 2020 and continuing at a lower power into early February (figure 15). On 9 April at 0840 scientists at the Belmont Observatory reported an explosion that generated an ash plume up to 8 km altitude that drifted mainly ENE (figure 20). Such reports are common for St. Vincent and the entire region. 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. There were no casualties caused by the eruption. 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 23-27 March, 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.

Periods of banded tremor associated with explosive activity and stronger pulses of ash emissions to higher altitudes began at 0330 on 10 April, lasting for periods of 20-30 minutes with 1-3 hour gaps. Satellite radar imagery acquired on 24 April indicated possible growth at the lava dome following the explosions on 18 and 22 April. Powered by www.VolcanoDiscovery.com A high-level seismic tremor was also detected at 1109 that lasted for 20 minutes. The phase of lava emission appears to have come to a halt, but crater observations will continue. 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 grow during 1-9 February. Lahars likely descended all valleys in the Red and Orange zones, and some were hot and visibly steaming. 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. The Dust Veil Index for the 1902 eruption of Soufrire was calculated at 300; the Krakatau 1883 eruption = 1,000. A few small explosions have taken place from the dome, but none were large enough to project material above the rim (about 300 m above the crater floor). Periods of banded tremor began at 0330 on 10 April, lasting for periods of 20-30 minutes with 1-3-hour gaps. The lake level has dropped about one foot per day in the last six days. UWI-SRC and the National Emergency Management Organisation (NEMO) both warned the public to stay away from drainages and areas prone to flooding, and noted that lahars have caused notable erosion and damage to drainages and parts of the coastline. Confirmed Eruption, 2020 BCE 75 years Two thermal hotspots were detected using the MODVOLC thermal algorithm on 24 April. The frequency of crater tremors continued on a greatly diminished scale and only six tremors were recorded during the past three weeks. The situation in the crater remains the same as it has been for more than a month. Additional satellite data. Ash was collected and photographs were taken. Table 1. Calderas of gravity-slide structures in the Lesser Antilles Island Arc?. "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. 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. The level of the water in the crater lake has dropped 3.1 m since 3 November. Multiple significant lahars were generated by rainfall during 28-29 April. Some daily earthquakes were recorded during 7-15 June. Activity during April 2021. No lava dome was visible, but a possible spine-like protrusion was seen through the clouds. Multiple lahars continued to be recorded by the seismic network within all drainages during 28-30 April due to heavy rainfall (figure 32). 1178, p. 425-533. Soufrire in St. Vincent. However the extrusion rate has decreased during the past 3 months, as shown in table 7. An "explosive" volcanic eruption has blanketed the Caribbean island of St Vincent in ash and smoke and forced thousands of people out of . A swarm of volcano-tectonic (VT) earthquakes began at 0638 on 5 April. 15 (Tomblin, 1968). It was approximately 900 m N to S, 750 m E to W, and at least 100 m deep, based on RADAR data (figure 29).

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. The observers noted that the small black-colored dome had grown on the WSW edge of the 1979 lava dome. 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. The viscosity of the new lava is high so that even if the dome grows to the point at which its flanks overlap the present crater rim, it is unlikely that molten lava will escape down the mountainside. No sub-surface earthquakes have been recorded in this period nor have any earthquakes been reported felt. The dome also grew taller and spread laterally to the NW and SE. The water temperature continues to decrease with minor fluctuations. The average SO2 flux was 992 tons/day on 23 April, again recorded from the W coast. Gas-and-steam plumes were often visible from Belmont Observatory, on Richmond Peak, about 6 km SSW of the crater. of Michigan; R. Fiske, SI. Gas-and-steam continued to rise from the top of the dome as well as along the contact of the old and new domes. After this explosion, the seismicity consisted primarily of 30-50 small explosion events per hour, which could be correlated with the ejection of steam puffs that sometimes contained a little ash. The water level was -97 feet on 15 May, -98 feet on 22 May, and -98.5 feet on 25 May, and is now 13.5 feet below the original level of the lake. The Grantley Adams International Airport (GAIA) in Barbados also closed. Periods of tremor and near-constant swarms of LP and hybrid events were recorded on 16 April. Between 50 and 200 very small local earthquakes continued to be recorded daily by the summit seismic station, but very few were detected by seismometers on the flanks. St. Vincent. 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. The highest point on the island is still 226 feet relative to the 3 November datum. Home; The gas emissions were most notable from a small depression at the top of the dome. This was the 30th distinct explosion since the explosive phase began. Credit: NOAA. The dome's growth rate was difficult to estimate, but was probably <0.5 x 106 m3/day in late May. There has been no significant change in seismicity since a several-day increase in the number of events in late June and early July. The small number of flow front rock avalanches observed during their 4-hour stay may indicate a rate of extrusion substantially lower than in late April. The eruption of Soufrire volcano, St Vincent AprilJune 1979. Information about large Quaternary eruptions (VEI >= 4) is cataloged in the, EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters. Table 5 is a list of observations made at the crater. 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 17-23 March, expanding to the N and S. A team visited the dome on 19 and 23 March to make observations, take measurements, and maintain monitoring equipment. 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). Max VEI: 4, 1979 Apr 13 - 1979 Oct 26 5 days Table 7. In at least 95% of historic eruptions at similar volcanoes where there has been any explosive activity, this has begun within the first two months of the onset of eruption. This explosion occurred 52 hours after the last one and was the 30th since the explosive phase started. We and our partners use cookies to Store and/or access information on a device.

Most of the more than 17,000 evacuees were allowed to return to their homes on 14 May, including residents of the two largest towns near the volcano, Georgetown and Chateaubelair. By Robin George Andrews Published April 9, 2021 10 min read This writer concludes that the explosiveness of Soufrire magmas is a function of gas, not silica content, there being no direct relationship between these two components. 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. Lava extrusion continued from the same vent that produced the 1971 dome and the 1979 explosions. Pyroclastic flows traveled about 6 km WSW, reached the ocean at Wallibou Bay, and extended past the coastline over the sea. According to a news article, residents of the island of St.Vincent reported smelling sulfur in towns as far S as Kingstown. Information Contacts: University of the West Indies Seismic Research Centre (UWI-SRC), University of the West Indies, St. Augustine, Trinidad & Tobago, West Indies (URL: http://www.uwiseismic.com/); National Emergency Management Organisation (NEMO), Government of Saint Vincent and the Grenadines, Bise, PO. Shepherd, J. Scientists observed damaged vegetation, likely caused by fire, on the NW part of the crater (just N of the dome). J. Volcanol. 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. Save up to 40% off the cover price when you subscribe to Discover magazine. An excursion by rowboat was made on 27 February by R. Arculus and K. Willis, geology research students from the University of Durham, England. 10 April 2021. Simon Carn noted that this makes the La Soufriere eruption the largest tropical SO2 emission since the 2011 Nabro eruption, and the largest in the Caribbean since satellite measurements began in 1979. Many of these minor explosions dislodge rocks from the island which have been made unstable by general ridge expansion. Card 1321 (01 December 1971) Lava dome growth in crater lake continues. Explosions and seismicity end; new lava dome in summit crater. Table 3. 1h 11m ago distance 2.9 mi. | February 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. The largest event was registered as a Mw 3.5 at 0920 and was felt by local residents. A change in character of an eruption like this is not uncommon. 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. Tremors in the vicinity of the crater continue to be recorded, at a rate of about 10/day for the past week. His report was confirmed 1 November by a government official who flew over the crater in a small plane.".

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. Robson G R, Tomblin J, 1966. 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. This is the first explosive eruption at La Soufrire since 1979, although lava has been erupting at the summit since late December 2020. J. Volcanol. SO2 measurements taken from a boat on the W coast yielded a flux of 1,036 tons/day. Lamb's preliminary estimate of Dust Veil Index (Lamb, 1970) for this eruption is from 3 to 9, probably nearer to 3. The mudflows disrupted road crossings in the Rabacca Valley (E flank) but otherwise did little property damage. Additionally, a new GPS monitoring station was placed in Fancy. The crater itself lies on the SW margin of a larger 2.2-km-wide caldera, which is breached widely to the SW as a result of slope failure. Starting at 1653 the monitoring network also began to detect volcano-tectonic (VT) earthquakes, some of which have been felt by nearby communities, including Fancy, Owia, and Sandy Bay. Live Volcano Webcams. Seismicity dropped to low levels after the explosion on 22 April and remained low through 27 April; only a few VT, LP, and hybrid earthquakes were recorded. The situation at the crater has maintained the current pattern over the past seven weeks. The distance from the S shore of the crater lake to the island is approximately 12 m. Table 2.

Information Contacts: H. Sigurdsson, Seismic Research Unit, University of the West Indies. A report on 6 February stated that the dome continued to spread laterally N and S, with N as the dominant growth direction. There is data available for 3 deformation periods. Compared to the previous drone survey on 12 February, the dome had grown roughly 6.3 million cubic meters. "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. Observations. 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.
