ABSTRACT

Unified Catalog of Earthquake Hypocenters and Magnitudes at Volcanoes in Alaska--1989 to 2018   [open pdf - 9MB]

From the Abstract: "The Alaska Volcano Observatory (AVO) has main-tained an earthquake catalog since 1989 that now contains over 120,000 hypocenters and magnitudes that occurred near Alaskan volcanoes. Since 1989 the seismic instrumentation and data acquisition and processing techniques have under-gone numerous changes as computer systems and seismic processing software have advanced and evolved. In this report we recalculate earthquake hypocenters and magnitudes in a consistent manner between October 1989 and January 2018. The new hypocenters and magnitudes are archived at the AVO within an AQMS [ANSS Quake Monitoring System] database and in the compressed UNIX tar file that accompanies this publication."
