Welcome to COMET

The Centre for Observation and Modelling of Earthquakes, Volcanoes and Tectonics (COMET) uses satellite measurements alongside ground-based observations and geophysical models to study earthquakes and volcanoes, and help understand the hazards they pose.

A national-scale community with considerable size and impact, COMET brings together world-leading scientists across the British Geological Survey (BGS) and 10 UK universities: Bristol, Cambridge, Durham, Leeds, Liverpool, Manchester, Newcastle, Oxford, Reading and UCL. We work closely with the Natural Environment Research Council (NERC), National Centre for Earth Observation (NCEO) and European Space Agency (ESA), as well as many other national and international partners.

Professor Greg Houseman, COMET Emeritus Scientist, elected a Fellow of The Royal Society

(Part 1) Connor Drooff, Michigan State University: “Slip and Slip Deficit: The M 7.8 July 2020 Simeonof Earthquake and Interseismic Coupling of the Aleutian Megathrust”


(Part 2) Xueming Xue, Michigan State University: “A 25‐Year History of Volcano Magma Supply in the East Central Aleutian Arc, Alaska”

The COMET+ webinar series aims to promote research collaborators of COMET scientists, particularly early-career researchers and those from under-represented groups. The goal is to provide a platform for these researchers to showcase their work to large and international audiences, opening doors to broader collaborative networks and enhancing the community’s diversity of backgrounds and ideas.
