Axial Seamount Earthquake Catalog

by William Wilcock

This simple web site provides access to a near-real time catalog of earthquake detections and HYPOINVERSE locations for the Ocean Observatories Initiative cabled observatory at Axial Seamount. The catalog is updated hourly and efforts are made to backfill locations from intervals when the high-sample-rate data are diverted by the Navy but later released. The near-real time aspects of this software are still in a test mode.

Catalog last updated at 20-Nov-2017 17:18:52 UTC (20-Nov-2017 09:18:52 Seattle) with locations up to 20-Nov-2017 17:00:00 UTC

Status of 200 Hz waveform data - Navy Diversion
