An updated and unified earthquake catalog (1787-2018) for seismic hazard assessment studies in Mexico

Earthquake and focal mechanism data have been compiled from various local, regional and international sources. Large earthquake events (MW≥ 6.5) have been carefully revised for their epicentral locations and magnitudes from trusted publications. Different magnitude-conversion relationships, compatible with local and regional ones, has been established to obtain unified moment magnitude estimates for the whole catalog. Completeness periods for the declustered catalog were estimated for the definition of appropriate seismic source models for the whole territory. The final unified Poissonian earthquake catalog spans from 1787 to 2018, covering a spatial extent of 13⁰N to 33⁰N and 91⁰W to 117⁰W.
