Logo of the ANSS. The Advanced National Seismic System (ANSS) is a collaboration of the United States Geological Survey (USGS) and regional, state, and academic partners that collects and analyzes data on significant earthquakes to provide near real-time (generally within 10 to 30 minutes [1]) information to emergency responders and officials, the news media, and the public. [2]
USGS researchers publish the results of their science in a variety of ways, including peer-reviewed scientific journals as well as in one of a variety of USGS Report Series [36] that include preliminary results, maps, data, and final results. A complete catalog of all USGS publications is available from the USGS Publications Warehouse. [37]
The U.S. Antarctic Resource Collection (USARC) is currently located at the USGS Library in Reston, VA, and contains materials from the former U.S. Antarctic Resource Center. When operational, the Center was a joint effort of the USGS National Mapping Division and the National Science Foundation United States Antarctic Program.
ShakeAlert is an earthquake early warning system (EEW) in the United States, developed and operated by the United States Geological Survey (USGS) and its partners. [1] As of 2021, the system issues alerts for the country's West Coast (specifically the states of California , Oregon and Washington ).
The USGS ANSS (Advanced National Seismic System) Comprehensive Catalog (ComCat) is the authoritative and preferred source for near-realtime information about earthquakes and other seismic events (such as nuclear weapons tests) of magnitude 5.0 or greater anywhere in the world. ANSS is focused on providing accurate and timely information about ...
This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality. Notice that 'free and open-source' requires that the source code is available and users are given a free software license.
It had six degrees or categories, has been described as "merely an adaptation" of the then-standard Rossi–Forel scale of 10 degrees, and is now "more or less forgotten". [3] Mercalli's second scale, published in 1902, was also an adaptation of the Rossi–Forel scale, retaining the 10 degrees and expanding the descriptions of each degree. [4]
The USGS DEM format is a self-contained (single file) set of ASCII-encoded (text) 1024-byte (1024 ASCII chars) blocks that fall into three record categories called A, B, and C. There is no cross-platform ambiguity since line ending control codes are not used, and all data including numbers is represented in readable text form.
