| The Carboneras Fault, located in the Southeast Iberian Peninsula, is one of those with the highest slip rate (?), among the active faults in Spain, and is also one of the longest (L), which also makes it one of the highest potential seismic, in terms of the scalar seismic moment that could be released (Mo). According to QAFI v3 (IGME, 2015), ? = 1.1 mm / year and L = 110.5 km, which would make possible an earthquake of magnitude Mw = 7.4, (using the of W & C'94 empirical relationship) with a recurrence interval of TR = 1150 years . The fault is strike slip and pleosysmic studies in it point to minimum of 6 events since the Mid Pleistocene observed in trenches along La Serrata (Moreno, 2010, Moreno et al., 2008) and an elapsed time for Mw 7.4 of 1178 years. On the other hand, the last major event reported historically in the fault is the one that occurred in 1522, with I (EMS) = IX and M = 6.5, which allows estimating an elapsed time of about 500 years for that magnitude. With the available data, hazard estimates have been developed from different fault modeling: 1) TC characteristic earthquake, 2) Brownian model of temporal dependence, 3) Renewal model and 4) Poisson model. The sensitivity of the results to the different source modeling is analyzed, and these are compared in turn with the PGA values of the latest seismic hazard map of Spain (UPM-IGN, 2013). Finally, we analize the impact of the results in the city of Almeria, which is one of the most vulnerable in southern Spain, which makes the impact spread to the seismic risk scenarios that can be expected due to future earthquakes. | |
