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.
Locations of quakes magnitude 2.5 or greater in the Wabash Valley (upper right) and New Madrid (lower left) Seismic Zones. The Wabash Valley seismic zone (also known as the Wabash Valley fault system or fault zone) is a tectonic region located in the Midwestern United States, centered on the valley of the lower Wabash River, along the state line between southeastern Illinois and southwestern ...
Pressure on the fault where the 1811–1812 New Madrid earthquakes occurred was believed to be increasing, [23] but a later study by Eric Calais of Purdue University and other experts concluded the land adjacent to the New Madrid fault was moving less than 0.2 mm (0.0079 in) a year, increasing the span between expected earthquakes on the fault ...

Isoseismal map of the earthquake (I–III are instrumental to slight, IV is moderate, V is rather strong, VI is strong, VII is very strong) The 1968 Illinois earthquake was the largest recorded earthquake in the "Prairie State", measuring 5.4 on the Richter scale. Although there were no fatalities, the earthquake caused considerable structural ...
Google Maps' location-tracking feature, known as Timeline, is undergoing a major update. Previously, Google announced plans to shift this data to local storage. Now, the company is sending out ...
The 2008 Illinois earthquake was one of the largest earthquakes ever recorded in the Midwest state of Illinois. This moderate strike-slip shock measured 5.2 on the moment magnitude scale and had a maximum Mercalli intensity of VII (Very strong) .
