St Vincent (CMC) –Scientists monitoring the La Soufrière volcano say several lahars were recorded on Tuesday even as seismic activity has remained low with only a few long-period, hybrid and volcano-tectonic earthquakes having been recorded in recent times.
A lahar is a rapidly flowing dense mixture of rock debris, ash and water. They have the consistency of wet concrete as they flow and can happen during and after eruptions.
The Seismic Research Centre (SRC) of the University of the West Indies (UWI) said that signals from several lahars were recorded on Tuesday during and after a period of rainfall.
