Abstract: In this work we used waveforms and the catalog of National Seismological Service (SSN) to analyze more than 20,000 events with M>= 4.0 for the period 2000-2018 with the goal of determining their moment tensor solutions. Because of large number of events, we a

Abstract: The pattern and level of damage during the 2017 Morelos-Puebla (Mw7.1) earthquake in central Mexico differ from those observed during the 1999 Tehuacán (Mw6.9) earthquake. Although these two intraslab events had similar magnitudes and depths, 57 km and 60 km

May Rayleigh waves propagate with group- and phase-velocities of opposite sign in the valley of Mexico city?

Peter G. Malischewsky

{{t.titulosSecciones.eresAutor}}

Abstract: On the basis of the group-velocity formula the occurrence of negative group velocities of Rayleigh waves is theoretically discussed for simplified models of Mexico City's basin by using results of a preceding article of the authors.
