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.

SeisMac is a free tool for recent Macintosh laptop computers that implements a real-time three-axis seismograph. The Development Of Very-Broad-Band Seismography: Quanterra And The Iris Collaboration Archived 2016-08-10 at the Wayback Machine discusses the history of development of the primary technology in global earthquake research.
During an earthquake, the stations send data to processing infrastructure in monitoring centers which, using various algorithms, are able to calculate the necessary information and generate alerts when needed. Initially, ShakeAlert processing centers were capable of detecting earthquakes at an early stage because of three specific algorithms.
According to the USGS, "ShakeMaps provide near-real-time maps of ground motion and shaking intensity following significant earthquakes. These maps are used by federal, state, and local organizations, both public and private, for post-earthquake response and recovery, public and scientific information, as well as for preparedness exercises and ...
The center operates a network of 20 broadband seismic stations and 15 short-period seismic stations to monitor the seismic activities in Pakistan and further detect any tsunami earthquake along Makran Subduction Zone. The center works in close coordination with National Tsunami Warning Centre, Karachi and Pakistan Navy. The pan-country network ...
Scientists have yet to pinpoint the fault that ruptured in New Jersey on April 5 and rattled much of the Northeast. Now, U.S. Geological Survey researchers are in the process of installing new ...
A collaboration with the IRIS Consortium began in 1984 as a result of a need to expand and succeed the WWSSN with the Global Seismographic Network (GSN). The GSN, originally funded entirely by the USGS under the National Earthquake Hazards Reduction Program (NEHRP), is now jointly supported by the National Science Foundation.
Time marks show when the earthquake occurred. Time is shown by half-hour (thirty-minute) units. Each rotation of the seismograph drum is thirty minutes. Therefore, on seismograms, each line measures thirty minutes. This is a more efficient way to read a seismogram. Secondly, there are the minute-marks.
