REMIS – Reliable Earthquake Magnitudes for Induced Seismicity (NERC)

A NERC-funded three-year project to quantify the uncertainty inherent in using seismic wave arrival times to jointly infer earthquake locations and magnitudes, and the seismic velocity structure of the subsurface.

Cartoon showing the joint event hypocenter–velocity tomography inference problem. The arrival times of waves from earthquakes at depth are the information we use. We perform fully non-linearised inference to obtain probabilities that a given event occurred within a certain volume and time, and also that any point in the subsurface has a certain range of velocities.
