1. Interpretación sismotectónica de la serie sísmica de Gérgal (2002, Mw 4.8) mediante datos sismológicos y de interferometría de RADAR (INSAR)

Author

Bejar, M., Herráiz, E., Martínez Díaz, J. J., López, C., Capote, Ramón, and Tsige, Meaza

Subjects
Gergal, RADAR interferometry, Focal mechanism
Abstract

This work analyzes the geological source of the Mw 4.8 February 4 2002, Gérgal earthquake. The interpretation of local geological data, the relocation of the aftershocks sequence using a local velocity model, the focal mechanism calculation and the interferometric study of the area using RADAR images give evidences that support a tensional stress source with a rupture plane oriented NW-SE to NNE-SSW

3. Estudio por interferometria de radar (Insar) del terremoto de Muía (Murcia) de febrero 1999 (mb: 4.8) aplicado a la caracterizacón de la fuente sismogenética

Abstract

The RADAR interferometry (INSAR) is a modern technique that offers the possibility to identify and quantify surface displacements using phase differences from two different RADAR images (Massonnet and Feigl, 1998). The result of an interferometric study applied to the February 1 999 (Mb: 4.8) Mula (Murcia) earthquake is shown in this work. The available seismological data for this earthquake give different focal mechanisms (reverse or strike-slip mechanism) depending on the applied method. The five coseismic interferograms show that the Mula mainshock produced a very small surface deformation, less than expected for a pure reverse and swallow source. This evidence and the surface geological data support a NE-SO strike-slip fault (probably the Crevillente fault) to be the seismogenetic source
