The La Soufrière volcano on St. Vincent, which first erupted on Friday continues to spew ash and smoke high into the atmosphere.
Weather satellites have captured dozens of eruptions since the volcano first blew its top last week, ash now spreading hundreds of miles eastward and extinguishing the sun in Barbados.
UPDATE: There were more eruptions from the #LaSoufrière #volcano this weekend. Yesterday, @NOAA's #GOES16🛰️ caught this close-up of another explosive eruption that launched ash and debris thousands of feet into the air over the island of St. Vincent. #lasoufriereeruption pic.twitter.com/IFKLp9vR0X

The sputtering volcano has spewed thousands of tons of ashen fine particulate matter miles into the atmosphere, captured by the GOES east weather satellite, which peers down from 22,236 miles above the Earth’s surface.
The satellite captured the first eruption at 8:41am Friday, the 8:50am scan revealing a vertically extensive plume of brown volcanic particulates injected high into the atmosphere.
Estimating the plume height at 9:00am using the length of the shadow and the angle of the sun indicates that volcanic material may have reached up to 38,000 feet in height. Satellites estimated that the top of the plume was as cold as minus-75 degrees Fahrenheit, corresponding to altitudes near 40,000 feet.
West-to-north-westerly winds initially fanned ashfall north of Barbados, but Saturday the breeze changed direction. That sent a thick column of ash directly over the island, the day turned into night by the eerie black clouds.

In the past 24 hours, eruptions have been occurring semi-regularly every couple of hours, each producing new plumes that drift off to the east. Satellites indicated that 10 eruptions had occurred since midnight Saturday.

Another huge eruption of the #LaSoufriere #volcano this morning. You can see the massive plume of ash and the shock wave emanating from the crater. Incredible! Imagery via #GOES16 pic.twitter.com/Z63PnR2Oi6

The volcano previously erupted in 1979, had been acting up since December. A new lava dome appeared before the new year and grew into February, prompting increased supervision by volcanologists.
