View Earthquake Map Faults 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 The. What is a "Quaternary" fault? A Quaternary fault is one that has been recognized at the surface and that has moved in the past 1,600,000 years (1.6 million years). That places fault movement within the Quaternary Period, which covers the last 2.6 million years. How do I find the nearest fault to a property or specific location? 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. A fault is a three-dimensional surface within the planet that might extend up to the surface or might be completely buried. In contrast, a fault line is where the fault cuts the Earth's surface… if indeed it does. The most prominent faults in each state are usually shown on a state's geologic map as black lines.

The New Madrid Seismic Zone (/ ˈ m æ d r ɪ d /), sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.. The New Madrid fault system was responsible for the 1811-12 New Madrid earthquakes. This list covers all faults and fault-systems that are either geologically important [clarification needed] or connected to prominent seismic activity.
