At 8:41 a.m. local time on 9 April 2021, La Soufrière volcano, a 1,234 m peak on the island of Saint Vincent, erupted explosively. Some two hours later at about 10:30 a.m., Landsat 8 acquired this image of volcanic ash billowing from the mountain; the plume obscures the volcano on the northern side of the island. The eruption – the volcano’s first explosive event since 1979 – prompted thousands of people to evacuate. The eruptions propelled ash and gas high into the atmosphere not only over Saint Vincent, but also over Barbados, 190 km (120 mi) away. Photo courtesy of NASA.
