Montserrat Volcano Observatory
Teaming up with Dr Matt Watson — a volcanologist from the University of Bristol, and Dr Emma Liu — a volcanologist from Cambridge University, they have been capturing samples of ash and measuring gas concentrations from directly within volcanic plumes. Integrating with the Guatemalan air traffic control DGAC , the team flew fixed-wing drones directly over the summit of Fuego volcano. They imaged the summit and were able to predict when and where the next paroxysmal eruption would occur with considerable accuracy. Collaboration between scientists and engineers makes this possible — engineers are capable of realising scientific endeavors; between us we can take new and exciting observations and measurements to assist with understanding and prediction of volcanic risks. The objective of the trip was to measure the gas concentrations within the plume — specifically the SO 2 concentration — using multigas sensors developed by Palermo University in Italy.
Its eruptions have rendered more than half of Montserrat uninhabitable, destroying the capital city, Plymouth , and causing widespread evacuations: about two-thirds of the population have left the island. The volcano is andesitic in nature, and the current pattern of activity includes periods of lava dome growth, punctuated by brief episodes of dome collapse which result in pyroclastic flows , ash venting, and explosive eruption. The volcano is monitored by the Montserrat Volcano Observatory. Volcanic gas emissions from this volcano are measured by a Multi-Component Gas Analyzer System , which detects pre-eruptive degassing of rising magmas, improving prediction of volcanic activity. The Centre Hills in the central part of the island and the Silver Hills in the north are older volcanic massifs related to the subduction zone.
