Soufrière St. Vincent volcano (West Indies, St. Vincent): twice length and volume of new lava dome since last update
On 19 March the University of the West Indies Seismic Research Centre (UWI-SRC) monitored the volcano by drone to detect of physical changes of the new lava dome.
The central active vent continues to feed the growing lava dome in north-west and south-east direction. The extruded lava dome is currently about 105 m tall, 243 m wide and 921 long (511 m on 4 Feb) with a volume of 13.13 million cubic meters (5.93 million cubic meters on 4 Feb). Its length and volume is almost twice since the last update on 4 February.
The observations confirmed ongoing sulfur dioxide (SO2) emissions concentrated on the top of the new dome as well as at the contact with the 1979 lava dome.
