Summary[edit]
DescriptionLa Soufrière volcano- before-and-after ESA23259245.jpeg |
English: Volcanic eruptions on Saint Vincent have blanketed the Caribbean island in ash leading to over 16 000 residents to be evacuated from their homes. False-colour images captured by the Copernicus Sentinel-2 mission show the aftermath of the explosive eruption that took place on 9 April 2021. La Soufrière is an active stratovolcano on the Caribbean island of Saint Vincent in Saint Vincent and the Grenadines. A series of explosive events began in April 2021, forming a plume of volcanic ash reaching 8 km in height, and generating pyroclastic flows down the volcano’s south and southwest flanks. The image on the left was captured on 8 April, one day before the first main eruption, while the image on the right was taken on 13 April, and shows the northern part of the island covered in ash. The images have been processed in a way that included the satellite’s near-infrared channel. This type of band combination is most commonly used to assess plant density and health, as plants reflect near-infrared and green light, while absorbing red. Since they reflect more near-infrared than green, dense, plant-covered land appears in bright red. In response to the eruption, the Copernicus Emergency Mapping Service was activated. The service uses satellite observations to help civil protection authorities and, in cases of disaster, the international humanitarian community, respond to emergencies. |
