Probabilistic seismic hazard analysis of events occurred in Albania

Abstract

Albania is a seismic region so the goal of many earthquake engineers is to ensure the durability of a structure for a given level of ground vibration. There are many uncertainties about magnitude, location and the intensity of the future earthquake. Probability methods allow us to speak quantitatively about variables phenomenon. Probabilistic Seismic Hazard Analysis (PSHA) aims to reveal these uncertain and to produce the distribution of the future earthquakes that may occur. The purpose of this paper is to discuss the calculation involved in PSHA and to give some qualifications about the probability of intense ground vibration at a place and their associated rates of exceedance. The results can be used to identify the ground vibration intensity, which has small probability of being exceeded. In calculation are involved the location and intensity of all the seismic events occurred in Albania.
