Microearthquake catalog from 2003-2004 for the East Pacific Rise (EPR) at 9°50N (investigators Maya Tolstoy and Felix Waldhauser)

This data set is the correlation-based, double-difference processed earthquake catalog derived from ocean bottom seismometers (OBS) deployed at the East Pacific Rise between October 2003 and April 2004. The data is in ASCII format and is described in detail in Waldhauser and Tolstoy, 2011 (see also Tolstoy et al., 2008 for an earlier, preliminary version of the catalog). The earthquake catalog was generated as part of the project called Seismic Monitoring of the 9N East Pacific Rise RIDGE 2000 Integrated Studies Site. Funding was from NSF grant OCE03-27283.
