Probabilistic Seismic Hazard Assessment for Libya
Abstract eng: This paper presents the results of a regional seismic hazard assessment undertaken for Libya and the offshore region. This area includes a number of major regional tectonic features including the Hellenic Arc and Calabrian Arc subduction zones, the stable continental Saharan Metacraton, forming part of the African Plate, and the Hün Graben in Libya where a magnitude 7.1Mw earthquake and a series of large aftershocks occurred in 1935. An earthquake catalogue has been compiled and critically reviewed for the region and seismic source zones and their associated magnitude recurrence parameters have been defined. Ground motion prediction equations have been selected based on the tectonic character of the source zones. The uncertainty in each element of the hazard assessment has been included using logic tree methodology. The seismic hazard results are presented in the form of geometric mean peak ground acceleration for selected cities and major oil and gas facilities in the region. The paper also discusses how these results compare with design values typically used for seismic design purposes in the region.
