Quake Data Merge Real Time Merged Catalog (QDM)
Entry ID: USGS_QDM

[ Get Service ]
[ Update this Record ]

Summary
Abstract: The Quake Data Merge Real Time Merged Catalog (QDM) software receives earthquake summary information and additional text from seismographic networks, eliminates duplicate and redundant information reported by different seismic networks, and produces a single, authoritative earthquake catalog. The process to generate this "composite" catalog follows selection rules set out by the ANSS to determine which earthquake information has the most authoritative information. This catalog can be used as input to other applications that require access to earthquake information in near-real time. The most likely method for receiving the event and text information is through the QDDS system.
