The New Madrid seismic zone (NMSZ), sometimes called the New Madrid fault line (or fault zone or fault system), 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.
This list covers all faults and fault-systems that are either geologically important [clarification needed] or connected to prominent seismic activity. [clarification needed] It is not intended to list every notable fault, but only major fault zones.
The Ramapo Fault has been blamed for several past earthquakes, but the specific association of any significant earthquake with this fault has yet to be demonstrated. [6] A damaging earthquake affecting New York City in 1884 was incorrectly argued to be caused by the Ramapo fault, likely because it is the most prominent mapped fault in the ...
Map of the Ramapo Fault System: Earthquake epicenter at Lebanon, NJ. Hopewell Fault (red) and Flemington Fault (light blue) join the Ramapo (yellow) fault near the quake epicenter.
A map by the California Geological Survey shows faults near the Lake Almanor area in Plumas County, where a magnitude 5.5 earthquake struck Thursday, May 11, 2023, followed by a magnitude 5.2 ...
Approximate location of the Seattle Fault Zone (and other faults). The section of the fault zone directly under "Seattle" corresponds to the red line in the photo at the top. (DGER [9]) One model of the Seattle Uplift: Cross-section (south to north) along the east side of central Puget Sound, looking west. TB = Tacoma Basin EPZ = East Passage ...
Brevard Fault Zone in its extent from Montgomery, Alabama to the North-Carolina-Virginia border. The Brevard Fault Zone is a 700-km [1] long and several km-wide thrust fault that extends from the North Carolina-Virginia border, runs through the north metro Atlanta area, and ends near Montgomery, Alabama.
The fault zone responsible for Thursday's 7.0 magnitude earthquake off the coast of California is not known to produce large tsunamis, but due to the size of the event, NOAA’s Tsunami Warning ...
