The network consists of 22 short-period and 6 broadband seismometers deployed in the fold-and-thrust belt of eastern Bangladesh (one cluster in the Sylhet Division with 15-25km spacing, and one cluster in the Chittagong Division with 20-40km spacing). Deployments are a mix of vaults and above-ground installations. The aim is to locate seismicity and study the structure of the fold belt.
