Abstract
A unified Mw-based earthquake catalog of seismic activity reported in Sudan and adjacent was performed. Data from local and international agencies were analyzed, duplicate events were identified and removed using CompiCat software. The priority for data entry was given to the Ambrasys et al (1994, 2001) (AMA), England, Van der Hilst and Buland (EHB), International Seismological Centre (ISC), Preliminary Determination of Earthquake (PDE) and King Saud University (KSU). The moment magnitude (Mw) was calculated for each event if not given by the original source using the international and local empirical magnitude conversion equations. A new relation was obtained in this study to convert Mb and Ms from International Seismological Center (ISC). For each entry, accessible information on the date, time, location, intensity, magnitude and source are given. The final catalog is confined to the time period 1408 - 2014 and Mw magnitude values ranges from 0.28-7.36. Based on this catalog the seismicity map of Sudan and adjacent regions was obtained. The earthquake catalog may use to assess the seismic hazard in the region.
