Earthquake Hazard

Seismic Hazard is the computation of the probability of occurrence of ground shaking in a given time period, to produce maps of seismic hazard and related uncertainties at appropriate scales. It is the main ingredient in the assessment of seismic risk and provides one of the main inputs in codes  for the earthquake resistant design of structures.

Current State

There has been two projects towards the  unified assessment and mapping of seismic hazard in Europe. The Global Seismic Hazard Assessment Program (GSHAP), a UN/IDNDR demonstration project, produced the first seismic hazard map for the European-Mediterranean region as part of the Global Seismic Hazard Map, based on the compilation and assemblage of hazard results obtained independently in different test areas and multinational programs (Adria, Ibero-Maghreb, Central-Northern Europe, Fennoscandia, Turkey and Greece, Caucasus, Near East, the Balkans). We were in charge of the Turkey-Greece test area which provided the opportunity of interaction with other European institutions.
The ESC-SESAME project (European Seismological Commission -IUGS Program Project no. 382) produced a  unified model for Probabilistic Seismic Hazard Assessment for Europe and the Mediterranean. We have jointly worked and  furthered our cooperation with European institutions involved in the project.
