'Dangerous' Volcanic Debris Flows Along Riverbed Amid La Soufriere Eruptions

Volcanic material considered to be "extremely dangerous" flowed along a riverbed in St Vincent on Monday, April 12, amid eruption activity of the island's La Soufriere volcano, officials https://www.facebook.com/nemosvg/posts/4006274946083098 said . Footage shot by Hayden Billingy shows the mixture of debris, pyroclastic material, mud and water - or "lahar" as it's known - flowing along the Rabacca Dry River in Georgetown. The National Emergency Management Organisation of St Vincent and the Grenadines https://www.facebook.com/nemosvg/posts/4006274946083098 urged residents not to gather near the river to view the pyroclastic flows. The University of the West Indies Seismic Research Centre https://www.facebook.com/uwiseismic/photos/a.10151097727459327/10151097731414327 said the Rabacca River serves as an "important drainage channel sweeping down from the volcano." The UN has warned a humanitarian crisis in the region around St Vincent and the Grenadines could last several months due to the eruptions. (Footage By Hayden Billingy/Storyful via Getty Images)
