We use continuous and survey GNSS data to image the spatial and temporal evolution of afterslip during the 2 months following the Mw 8.3 2015 Illapel earthquake. Our approach solves for the incremental daily slip at the subduction interface using nonnegative least squares with spatial and temporal Laplacian regularization constraints. We find...

An earthquake sequence occurred in the Atacama region of Chile throughout September 2020. The sequence initiated by a mainshock of magnitude = 6.9, followed 17 hours later by a = 6.4 aftershock. The sequence lasted several weeks, during which more than a thousand events larger than = 1 occurred, including several larger earthquakes of...
