[1] Energy from seismic events traveling up a subduction zone is frequently associated with significant large-amplitude, high-frequency signals with sustained long coda. Such seismic waves guided by the subducted plate with high wave velocity and high Q can cause surprisingly large seismic intensity in the fore-arc area. In this study, we characterize the guiding behavior of the subducted Phili...
Hillslope instability has been thought to be one of the most important factors for landslide susceptibility. In this study, we apply geomorphic analysis using multi-temporal DEM data and shake intensity analysis to evaluate the topographic characteristics of the landslide areas. There are many geomorphologic analysis methods such as roughness, slope aspect, which are also as useful as slope ana...
The three volcanoes that are the object of this paper show different types of activity that are representative of the large variety of volcanism present in the Central Mediterranean area. Etna and Stromboli are sub-aerial volcanoes, with significant part of their structure under the sea, while the Marsili Seamount is submerged, and its activity is still open to debate. The study of these volcan...
This paper briefly reviews the development of earthquake resistant design of buildings. The state-of-the-art of seismic design is discussed from the viewpoint of the performance criteria of buildings. These are (a) serviceability from frequent minor-intensity earthquake motions, (b) repairability from an infrequent but major-intensity earthquake motion, and (c) life safety from the maximum poss...
Vulnerability assessment of structures encounter many uncertainties like seismic excitations intensity and response of structures. The most common approach adopted to deal with these uncertainties is vulnerability assessment through fragility functions. Fragility functions exhibit the probability of exceeding a state namely performance-level as a function of seismic intensity. A common approach...
Las estructuras subterráneas se desempeñan como medios para llevar a cabo actividades esenciales en una sociedad moderna. Por lo tanto, su apropiado desempeño sísmico es importante la reducción del riesgo de desastres. El presente trabajo trata sobre los efectos sísmicos las ubicadas zonas altamente sísmicas, costa Perú. Se empleó el programa cómputo FLAC realizar varios análisis dinámicos secc...
