University of the West Indies Seismic Research Centre (UWI-SRC) reported that seismicity at Soufrière St.
Vincent (often simply referred to as ?La Soufriere?) remained low during 28 April-4 May, with a few long-period, hybrid, and volcano-tectonic earthquakes recorded daily.
Multiple significant lahars were generated by rainfall during 28-29 April.
Lahars likely descended all valleys in the Red and Orange zones, and some were hot and visibly steaming.
Trees brought down by lahars were swept to the sea; floating logs created hazardous conditions for small boats along the coastline.
UWI-SRC and the National Emergency Management Organisation (NEMO) both warned the public to stay away from drainages and areas prone to flooding, and noted that lahars have caused notable erosion and damage to drainages and parts of the coastline.
Smaller lahars were recorded during the mornings of 30 April and 1 May.
Multiple lahars were detected in likely all the volcano?s drainages for a period of about six hours on 3 May, with the most intense lahars occurring during 1100-1200.
Sulfur dioxide emissions were measured from a boat near the W coast, yielding a flux of 1,036 tons per day.
Photos showed people in Sandy Bay shoveling off ash from rooftops on 4 May.
The volcano Alert Level remained at Red.
