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.
A major earthquake measuring 7.4 hit Taiwan early Wednesday, killing 9 and injuring at least 1,000. A 7.4 earthquake is exponentially more destructive than the 4.8 quake that struck central New ...
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 ...
The main scientific goal of the centre is the definitive compilation of earthquake information and the readings on which they are based. Collection of reports of earthquake effects is also an important part of its operation and the Centre recomputes the location and occurrence time of earthquakes worldwide, making use of all available information.
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:
Monitoring station map of China's national earthquake early warning system. The earliest earthquake warning system in China was built in the 1990s. [23] The devastation of the 2008 Sichuan earthquake stimulated China's investment in nationwide earthquake early warning systems (EEWS). Large amounts of monitoring stations, sensors, and analytic ...
