Forty-two (42) years ago today in 1979, La Soufrière Volcano erupted in Saint Vincent and the Grenadines (SVG). To commemorate its 42nd anniversary, La Soufrière had another explosive episode this morning (Tuesday 13th April 2021), beginning at 6:30am.
According to Professor Richie Robertson, the latest explosion is not as energetic as previous ones. The Professor notes that classic Vulcanian eruptions are possible over the next few days. There was a huge explosion at La Soufrière yesterday morning at 4:15am. Dome collapse and pyroclastic flows were observed along the valleys on the Eastern and Western coast. Pyroclastic flows (aka Pyroclastic Density Currents - PDCs) or surges are NOT lava flows, according to UWI Seismic Research Centre. They are moving mixtures of ash, rock fragments and produced by an gas eruption. They travel down valleys and cause total devastation.
Prime Minister of Saint Vincent and the Grenadines, Dr. Ralph Gonsalves, revealed this morning that there are still a number of persons who refuse to evacuate.
The scene in SVG has been described as resembling a “battle zone” since the first eruption of La Soufrière Volcano on Friday (9th April 2021).
La Soufrière Scientific Update 13/04/21 - 6am
NOTE: This update was prepared prior to an explosion which occurred at 6:30am local time. 1. Seismic activity at La Soufrière, Saint Vincent continued the pattern established yesterday, with short bands of continuous seismic tremor interspersed with long-period earthquakes. 2. Following the latest band of tremor, at 1:30am, the long-period earthquakes have steadily become more frequent. 3. Audible venting was heard associated with some periods of tremor and long-period earthquake activity. 4. The Volcano continues to erupt explosively and has now begun to generate pyroclastic density currents - hot (200°C - 700°C), ground-hugging flows of ash and debris. 5. Explosions and accompanying ashfall, of similar or larger magnitude, are likely to continue to occur over the next few days impacting Saint Vincent and neighbouring islands. 6. The Volcano is at alert level Red. 7. Visit the International Volcanic Hazard Health Network for information and resources on living with Volcanic ash - www.ivhhn.org/information. La Soufrière Scientific Update 12/04/21 - 6pm 1. The pattern of seismic activity changed again, with the end of the episodes of high-amplitude tremor, two (2) - eight (8) hours apart. 2. Three (3) episodes of tremor have been recorded since 6am, two (2) of them lower-amplitude and the third, at about 5pm, was high-amplitude. 3. The episodes continue to coincide with periods of enhanced venting or explosive activity. 4. A reconnaissance of the entire north coast of Saint Vincent from Chateaubelair to Georgetown with assistance from the Coast Guard. 5. Observations made indicate that Pyroclastic Density Currents (PDCs) had descended several valleys on the Southern and Western flanks of the Volcano and had reached the sea at Morne Ronde, Larikai and Trois Loupes Bay. 6. Extensive damage to vegetation was noted in an area extending from Larikai Bay to Turner Bay on the West coast. 7. No other areas along the coast had been affected by PDCs but villages located on the Eastern flank of the Volcano had been affected by heavy ashfall. 8. Explosions and accompanying ashfall, of similar or larger magnitude, are likely to continue to occur over the next few days with the chance of PDCs occurring.
