The 11 May 2011 earthquake at Lorca (SE Spain) viewed in a structural-tectonic context

Abstract: Abstract. The Lorca earthquake of 11 May 2011 in the Betic Cordillera of SE Spain occurred almost exactly on the Alhama de Murcia fault, a marked fault that forms part of a NE-SW trending belt of faults and thrusts. The fault belt is reminiscent of a strike-slip corridor, but recent structural studies have provided clear evidence for reverse motions on these faults. Focal mechanisms of the main earthquake, but also of a foreshock, are strikingly consistent with structural observations on the Alhama de Murcia f… Show more

“…In spite of its moderate size this earthquake produced massive damage in this city. This earthquake has been related to the activity of the AMF (i. e. IGME, 2011;Vissers and Meijninger, 2011; LopezComino et al, 2012;. In recent years several studies have focused on the characterization of the paleoseismic activity and the determination of AMF seismic parameters: slip rate, recurrence interval, maximum magnitude Masana et al, 2004, 2005, Masana, 2010Ortuño et al, 2012).…”

“…Echeverria et al (2013) proposed an average reverse-sinistral geodetic lateral slip rate for the Alhama de Murcia fault of 1.5 mm/yr. This fault is seismogenic, having produced paleoseismic events up to Mw 7.0 (Masana et al, 2004), several I MSK VII-VIII earthquakes in the last 500 years, and the 2011 Mw = 5.2 Lorca earthquake, the most recent damaging earthquake in Iberia (López-Comino et al, 2012;Martínez-Díaz et al, 2012b;Vissers and Meijninger, 2011).…”

“…A pesar de que la FAM es la fuente sísmica más plausible en el área, los informes preliminares en los primeros meses no aportan datos concluyentes que atribuyeran el terremoto a la FAM (Martínez-Díaz et al, 2011;Vissers and Meijninger, 2011). Los análisis de datos sismológicos fueron los que proporcionaron las primeras evidencias de que la FAM fue la falla responsable del terremoto de Lorca (Rueda et al, 2011;López-Comino et al, 2012).…”

“…Las localizaciones oficiales accesibles a través del catálogo público del IGN no definen ninguna orientación reconocible y muestra una gran dispersión al Este de Lorca (IGN, 2011). Sin embargo, las fallas reconocidas con métodos geológicos indicaban que la fuente sísmica más probable podía ser el plano NE-SO (Martínez-Díaz et al, 2011;Vissers and Meijninger, 2011). Estudios de directividad de la energía sísmica liberada y una refinada relocalización de la serie han confirmado que la falla responsable fue la falla de Alhama de Murcia, FAM (Rueda et al, 2011;López-Comino et al, 2012).…”
