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.

Earthquakes in the greater New York City area affect most of New Jersey, the most densely populated state in the United States, as well as New York City. It is difficult to discern the extent to which the Ramapo fault itself (or any other specific mapped fault in the area) might be any more of a source of future earthquakes than any other parts ...
An earthquake is what happens when the seismic energy from plates slipping past each other rattles the planet's surface. Those seismic waves are like ripples on a pond, the USGS said.
Earthquake magnitudes are based on data from the USGS. Seismic activity during the year 2024 was much lower than the rest of the 21st century, with only 100 earthquakes exceeding magnitude six, the lowest since 1982. [1] There were also no earthquakes exceeding ≥M8 for the third year in a row.
Earthquakes in Maryland are infrequent and small due to the state's distance from seismic/earthquake zones. [4] [5] The M5.8 Virginia earthquake in 2011 was felt moderately throughout Maryland. Buildings in the state are not well-designed for earthquakes and can suffer damage easily. [6]
A magnitude 4.1 earthquake was reported at 1:49 p.m. Wednesday two miles from Corona, according to the U.S. Geological Survey. The earthquake occurred three miles from Anaheim, three miles from ...
The epicenters of over 4,000 earthquakes can be identified from seismic measurements since 1974, originating from the seismic activity of the Reelfoot Rift. Forecasts for the next 50 years estimate a 7–10% chance of a major earthquake like those of 1811–1812, and a 25–40% chance of a quake of magnitude 6 or greater.
