Activity at the volcano remains low. 4 rockfall signals and one volcano-tectonic earthquake were recorded in the last 24 hours.
A detailed dome map has been completed using theodolite surveys and photographs taken from the ground and the helicopter. The dome currently has a volume of 76.8 million cubic metres and its highest point is at the top of the White River Valley at 977 metres above sea level. The dome was split deeply by the collapse on July 3rd last year and by subsequent events. The northern part of the dome, which comprises three main buttresses above Gages, the northern flank and Tar River, contains two-thirds of the total dome volume. The scar in the dome cuts deeply into the ancient rock of English's Crater. The scar cuts up to 100m deep into the ancient crater floor and has removed a minimum of 5.4 million cubic metres of old rock from this area
Residents of Montserrat are advised to keep listening to ZJB Radio Montserrat for information in case of any changes in the state of the volcano.
