Thanks you for the quick response Cheryl. I'm more interested in a table of the hypocenters with their coordinates, depths, times, magnitudes etc. than the raw data. I am not a seismologist, I'm a structural geologist looking to model the structures beneath volcanoes using 3D seismic events. The original report that I mentioned has events located with magnitudes as low as -9.0. I am much more interested in the micro-seismicity to do the work I mentioned above.

Hello Michael, I think this report might also contain what you are looking for (and then some!) https://pubs.er.usgs.gov/publication/sir20195037 If you're still seeking the data in the original report, please let me know. Thank you Cheryl Hello, I came across the above mentioned publication published in 1996 (Open-File Report 96-70) and was wondering if the hypo-center catalog is still available? The report mentions that the origin times, focal coordinates, magnitudes, and related parameters for 3,938 earthquakes from January 1, 1991 through December 31, 1993 are contained in a file on an accompanying floppy disk. Is this file somehow still available digitally? Thank you, -Michael
