Hydroacoustic catalogs along the Southeast Indian Ridge

We present the hydroacoustic event catalogs associated with seven seismic swarms between July 2012 and December 2020 along the Southeast Indian Ridge. These swarms are recorded by a network of 6 to 8 autonomous underwater hydrophones of OHASISBIO network and three permanent hydroacoustic stations maintained by International Monitoring System of Comprehensive Nulcear Test-Ban-Treaty organization. Out of seven swarms, one swarm occurs along the transform boundary at 26°21’S, two are centered on the 28°S segment, three on the 29°S segment, and one along the J3 segment, which is an overlapping spreading center south of the SPA plateau.
