File CChile_catalog.txt: Seismicity catalog for Central Chile, containing 11,931 events covering the time span 29/04/2014 to 31/12/2018, in a simple ASCII file. The catalog is described in detail in the article "Microseismicity appears to outline highly coupled regions on the Central Chile megathrust" (https://doi.org/10.1029/2021JB022252) File CChile_catalog_ISC.txt: Version of the same catalog that was homogenized with the ISC bulletin. We added a total of 110 earthquakes, nearly all of them occurring in the 2015 Illapel and 2017 Valparaiso earthquake sequences, that had originally been missed with our automatic approach, but for which picks were available from ISC. Based on these picks from ISC, we processed these events in the same way as the rest of the catalog. For both files, the columns are: Date, time, latitude [decimal degrees], longitude [decimal degrees], depth [km], magnitude [ML]. Please also refer to the abovementioned publication when using this dataset.
