Repeated palaeoseismic activity of the Ventas de Zafarraya fault (S Spain) and its relation with the 1884 Andalusian earthquake

One of the most destructive historical earthquakes (M [asymptotically =]6.7) in Spain occurred in 1884 along the normal Ventas de Zafarraya Fault located in the Central Betic Cordilleras. Palaeoseismic and radiocarbon data presented in this study are the first to constrain the timing of the pre-1884...

Description
Summary:One of the most destructive historical earthquakes (M [asymptotically =]6.7) in Spain occurred in 1884 along the normal Ventas de Zafarraya Fault located in the Central Betic Cordilleras. Palaeoseismic and radiocarbon data presented in this study are the first to constrain the timing of the pre-1884 fault history in the last 10 ka. These data yield a recurrence interval of between 2 and 3 ka for major earthquakes, under the assumption of uniform return periods along the normal fault. The Holocene slip rate is estimated to be in the order of 0.35±0.05 mm/year, which is significantly higher than the mean slip rate of 0.17±0.03 mm/year since the Tortonian. Several of the most important deformations and secondary features, such as landslides and liquefaction, are related to strong ground motion and document the Holocene activity of the Ventas de Zafarraya Fault.[PUBLICATION ABSTRACT]
