RELEIF INFORMATION ON EARTHQUAKE FAULTING (RELEIF)
European Commission
contract N° EVG1 - 2002 - 00069


The RELIEF programme consists of multidisciplinary studies of two large and devastating earthquakes, an assessment of their dynamic coupling, and an integrated analysis of their consequent seismic-hazard implications. The aim of the project is to improve observational and theoretical methodologies for seismic-hazard assessment, and to establish models of crustal processes, fault mechanics and site behaviour that can be applied more widely in the European domain.

A web site with more scientific details of the RELIEF project can be found at : http://www.ingv.it/paleo/RELIEF

We identify 4 main objectives:

(1) Long-term faulting behaviour, determined through systematic geological, geomorphological and paleoseismological analyses (with trenching) along each of the 1999 earthquake rupture-segment and nearby earthquake faults to document the earthquake characteristics (fault dimensions, slip/event, slip rate, stress drop, elapsed time and return period of seismic events, seismic moment and moment magnitude) during the Holocene and late Pleistocene;

(2) Understanding of physical dimension and dynamic properties of earthquake faulting (coupling between faults, the interseismic strain and fault loading characteristics), determined through use of Radar interferometry and Digital Elevation Modelling, and comparisons with the source time function (seismometer and strong motion waveform analyses);

(3) Detailed understanding of the relationship between site effects (including response spectra) and the earthquake rupture process;

(4) Development of a new time-dependent seismic-hazard approach based on the integration of multidisciplinary datasets, and thereby contribute to improved seismic-risk assessments for the Istanbul area




RELIEF is a 3-year project.

Date of commencement = 1 December 2002
