European-Mediterranean regional centroid-moment tensor catalog: solutions for years 2001 and 2002

Abstract

We present regional centroid-moment tensor (RCMT) solutions for 168 moderate-magnitude earthquakes that occurred in the European-Mediterranean region during 2001 and 2002. Events with moment magnitudes as low as 4.0 were successfully analyzed, although this low threshold is only achievable in regions with the best azimuthal coverage and with stations at a few hundred kilometers distance. Earthquakes with focal depths from 10 to more than 200 km were analyzed. Comparison with standard Harvard CMTs, when available, shows good agreement. The solutions shown in this paper represent an addition to the European-Mediterranean RCMT catalog that we are maintaining. The RCMT catalog now spans 6 years, from 1997 to 2002, and contains 420 solutions. We also outline the main seismic sequences that occurred in the European-Mediterranean region during 2001–2002.
