A seismic hazard is the probability that an earthquake will occur in a given geographic area, within a given window of time, and with ground motion intensity exceeding a given threshold. [ 1 ] [ 2 ] With a hazard thus estimated, risk can be assessed and included in such areas as building codes for standard buildings, designing larger buildings ...
According to USGS seismologist, Jeanne L. Hardebeck, the Shoreline Fault has potential to trigger an earthquake of 6.4–6.8 magnitude, [24] while the company asserts the facility is designed to withstand a 7.5 magnitude quake, [25] and NRC's estimate of the risk each year of an earthquake intense enough to cause core damage to the reactor at ...
Second, the NEIC collects and provides to scientists and to the public an extensive seismic database that serves as a solid foundation for scientific research, principally through the operation of modern digital national and global seismograph networks and through cooperative international agreements. The NEIC is the U.S. national data center ...
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.

Seismic hazard and seismicity map for Oklahoma and vicinity for the year 2017 – incorporates hazard from induced seismicity 2023 National Seismic Hazard Model in Oklahoma from the United States Geological Survey – does not incorporate hazard from induced seismicity
Earthquake prediction is a branch of the science of seismology concerned with the specification of the time, location, and magnitude of future earthquakes within stated limits, [1] [a] and particularly "the determination of parameters for the next strong earthquake to occur in a region". [2]
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 Tacoma Fault Zone marks the south end of the Seattle Uplift, of which the similar and related Seattle Fault Zone marks the north end. This uplift is believed to be either a slab of rock about 15 km thick being pushed up a ramp, or a wedge being popped up between these two faults, by tectonic forces from the south or south-west as tectonic plates riding on top of the Juan de Fuca plate are ...
