This map is one of a series of seismicity maps produced by the U.S. Geological Survey that show earthquake data of individual states or groups of states at the scale of 1:1,000,000. This map shows only those earthquakes with epicenters located within the boundaries of Texas, even though earthquakes in nearby states may have been felt or may ...
This map shows only those earthquakes with epicenters located within the boundaries of Texas, even though earthquakes in nearby states may have been felt or may have caused damage in Texas. The data in table 1 were used to compile the seismicity map; these data are a corrected, expanded, and updated (through 1987) version of the data used by ...
NRC-070 - U.S. Seismic Zone Map based on 1997 Uniform Building Code (UBC) map.
The maps displayed below show how earthquake hazards vary across the United States. Hazards are measured as the likelihood of experiencing earthquake shaking of various intensities.
Earthquake hazard map showing peak ground accelerations having a 2 percent probability of being exceeded in 50 years, for a firm rock site. The map is based on the USGS models for the conterminous U.S. (2023), Hawaii (2021), and Alaska (2023).
For each data region, researchers have compiled large, multidisciplinary datasets to map and characterize faults within each of these significant seismic regions. Fort Worth Basin. Delaware Basin.
The current map delineates "non-tectonic" quake activity in areas where man-made earthquakes have been studied. A seismic hazard map is essentially what it sounds like: a map that shows the potential for earthquakes in certain areas.
The U.S. Geological Survey (USGS) National Seismic Hazard Map shows the strength of ground shaking that has a 1 in 50 chance of being exceeded in a particular place in the lower 48 states over a period of 50 years.
