• Resumen

  • We present an approach developed to estimate the seismically-induced landslide susceptibility of the Alcoy (Alicante) area. It combines the Newmark's method of evaluation of slope stability with a seismic hazard study o f the region through a CIS. The obtained results show that the distribution of susceptible areas is closely related to the position of river valleys, specially the Molinar and Serpis rivers. Due to A lcoy city has developed around these rivers, some zones of the city show moderate to high susceptibility, which is in accordance with historical data which describe the occurrence of seismically-induced landslides along these valleys. The results emphasize areas of susceptibility that actually are being occupied, thus pointing out the necessity o f incorporating this information into the land use planning.
