Ground Truth Database for Regional Seismic Research in the Middle East and North Africa

Abstract

Our objective has been to collect, format, analyze and distribute waveforms, phase readings, and other information for regional events in the Middle East and North Africa (ME-NA). Sparse station coverage by the network of the prototype International Data Center (pIDC) has been augmented with data from other archives, primarily the IRIS Data Management Center. Our products include careful and consistent seismic data analysis; only two analysts have worked on this project, both previous Lead Analysts at the pIDC. To date, we have processed more than 900 events and identified over 8,100 regional phases. All information for one event is packaged in a regular file and can therefore be delivered via anonymous FTP. Unique identification numbers in the database tables allow any number of these events to be merged into one large dataset or loaded into an RDBMS. This report summarizes each of the completed datasets and gives an overview of how they were compiled. Additional documentation, available from the GTDB Web Site (URL: http://es1.multimax.com/^gtdb), includes maps, seismic bulletins, waveform and signal quality comments, analysis summaries, and sample waveform plots.
