Social Share La Soufriere volcano is “quiet” but secondary hazards like lahar (mudflow), caused by heavy overnight and early morning rains, are posing a new kind of danger to the people of St Vincent and the Grenadines. Speaking on the daily update on NBC Radio on Thursday, seismologist Roderick Stewart said the equipment that was monitoring the volcano indicated it was quiet and there were no tremors, but lahars were occurring in all of the major drainage valleys and these could have caused damage as they passed from the volcano to the sea. Stewart, who is monitoring from the Belmont base, said this would lead to flooding because lahar tends to block existing culverts and drainage and cut new roads and paths.
