Geostatistical Characterization of a Probable Active Magmatic Intrusion, Based on Recent Seismicity in the State of Hidalgo
Abstract
Typically, low intensity and shallow seismicity occurs in the central portion of the State of Hidalgo. Simple statistics, ordinary Kriging analysis, and a Kernel density map were combined in order to investigate the seismicity of central Hidalgo, between 1999 and 2017. Findings show that the shallow seismicity has increased in the past four years, in spite of an inferred continental crust thickness of ca. 45 km, and strongly suggest the emplacement of an active, semicircular, magmatic body. Finally, a tectonic model is proposed in the context of the subduction system of southern Mexico and the geologic evolution of the central sector of the Trans Mexican Volcanic Belt, in Hidalgo.
