Quake Data Merge Real Time Merged Catalog (QDM)
receives earthquake summary information and additional text from seismographic networks, eliminates duplicate and redundant information reported by different seismic networks, and produces a composite earthquake catalog. USGS software.
Quake Data Distribution System (QDDS)
a method for distributing earthquake data over the Internet in near-real time using a structure similar to a classical client- server system called a hub-leaf system. USGS software.
