Abstract
En Sierra Elvira existen deslizamientos de masas coherentes de
calizas. Su formación fue favorecida por la litología, la estructura del
área (un anticlinal volcado vergente al sur y la presencia de fallas
importantes). El núcleo del anticlinal quedó expuesto cuando la erosión le quitó su envoltura más friable. Esos deslizamientos fueron
probablemente desencadenados por paleoterremotos importantes
acaecidos en tiempos geológicos recientes, hipótesis que se apoya
en la intensa actividad sísmica actual y reciente de la región
In Sierra Elvira there are coherent limestone mass slides. In addition to the lithology, the structure (a south-vergent anticline and important faults) favored the sliding. The core of the anticline was exposed when the erosion took away its softer envelope. These landslides were probably triggered by important paleoearthquakes accounted in recent times, a hypothesis that is supported by the intense active seismicity existing in the area
