The Quaternary Fault and Fold Database of the United States database contains information on faults and associated folds in the United States that demonstrate geological evidence of coseismic surface deformation in large earthquakes during the past 1.6 million years (Myr). Interactive fault map Database Search Contributors Download Data: KML (Google Earth) Files (13 MB KMZ) - includes 5 fault layers: Historic, Holocene to Latest Pleistocene, Late Quaternary, Mid-Late Quaternary, Quaternary GIS files (16 MB ZIP file)

Interactive fault map and comprehensive geologically based information on known or suspected active faults and folds in the United States. Also, generalized fault data used in the hazard maps. View Fault Map Earthquake Scenarios Earthquake scenarios describe the expected ground motions and effects of specific hypothetical large earthquakes. An online map of United States Quaternary faults (faults active in the last 1.6 million years which places them within the Quaternary Period) is available via the Quaternary Fault and Fold Database . There is an interactive map application to view the faults online and a separate database search function. Explore the interactive fault map of the United States, created by the US Geological Survey (USGS). This web app allows you to view and search for active faults and fault zones, as well as historical earthquake data and seismic hazard zones. You can also access other USGS mapping resources and tools, such as planetary geology, topography, hydrography, and more. Faults vs. Fault Lines on a Map In order to answer this question, we first need to explain some basics about faults. Faults are different from fault lines. A fault is a three-dimensional surface within the planet that might extend up to the surface or might be completely buried.

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. These maps are used in determining building seismic codes, insurance rates, and other This layer shows surface faults traces that are believed to be sources of M 6+ earthquakes during the Quaternary geologic period (past 1.6 million years). Google Earth File In this layer, the fault colors represent age of last movement on the fault, from 1.6 million years ago to the present.
An online map of United States Quaternary faults (faults active in the last 1.6 million years which places them within the Quaternary Period) is available via the Quaternary Fault and Fold Database. There is an interactive map application to view the faults online and a separate database search function. On Thursday, the United States Geological Survey (USGS) announced updated U.S. National Seismic Hazard Maps, which reflect the most current scientific views on where future earthquakes will.
The Connection with Fault Lines. r/Missing411
This map gives an overview of geologically young faults and is intended to help in evaluation of the potential activity of faulting nationally. This map is a progress report. Because of its scale, it cannot be used as an index of specific faults or fault hazards. However, it offers a synopsis, as of 1975, of more extensive data that must be taken into consideration in assessments of hazards. Follow; Twitter; Facebook; GitHub; Flickr; YouTube; Instagram
