abstract = {The 2013 seismic sequence at the Castor injection platform offshore Spain, including three
earthquakes of magnitude 4.1, occurred during the initial filling of a planned Underground Gas
Storage facility. The Castor sequence is one of the most important cases of induced seismicity
in Europe and a rare example of seismicity induced by gas injection into a depleted oil
field. Here we use advanced seismological techniques applied to an enhanced waveform
dataset, to resolve the geometry of the faults, develop a greatly enlarged seismicity catalog
and record details of the rupture kinematics. The sequence occurred by progressive fault
failure and unlocking, with seismicity initially migrating away from the injection points,
triggered by pore pressure diffusion, and then back again, breaking larger asperities loaded to
higher stress and producing the largest earthquakes. Seismicity occurred almost exclusively
on a secondary fault, located below the reservoir, dipping opposite from the reservoir
bounding fault.},
