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.

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 ...
Map showing the amount of advance warning time that might be available from ShakeAlert for several plausible future earthquake scenarios. [1]Initially the system has been developed to monitor and alert the West Coast of the United States, an area with significant seismic risk due to the San Andreas fault zone and the Cascadia subduction zone.
As Iceland has experienced a seismic swarm of 30,000 earthquakes in the last three weeks, Lydia Patrick maps which areas have been hit by the worst of the tremors:
The map shows all earthquake activity detected by the Icelandic Met Office in the past 48 hours. Green stars represent earthquakes that were over a magintude of 3.0 (Icelandic Met Office) 800 ...
Large amounts of monitoring stations, sensors, and analytic systems were installed to improve the accuracy, responsiveness, and comprehensiveness of the earthquake data. In June 2019, the Chengdu Hi-Tech Disaster Reduction Institution, part of the national EEWS system, successfully warned various townships of a 6.0M earthquake 10–27 seconds ...
The IMO said an earthquake of 5.0 magnitude — the largest since seismic activity began on October 25 — was measured by Fagradalsfjall, a volcano located about 19 miles from the capital city of ...
Between 1’000 and 1’500 earthquakes a year are recorded in Switzerland and its immediate neighboring countries. Actually, between 10 and 20 quakes a year are strong enough to be felt by citizens, usually those with a magnitude of 2.5 or above. A strong earthquake with a magnitude of approximately 6 occurs every 50 to 100 years on average.
