It is believed that the Marianna Fault has previously experienced an earthquake that would have measured 7.0 on the Richter scale, and may well do so again. [1] Al-Shukri believes that the fault was created 5,000 years ago. [3] Previously, the predicted earthquake damage Marianna, Arkansas might receive from the more distant New Madrid Fault ...
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 ...

A fault off the Pacific coast could devastate Washington, Oregon and Northern California with a major earthquake and tsunami. Researchers mapped it comprehensively for the first time.
The fault runs offshore along the West Coast from Northern California to northern Vancouver Island in Canada. It is capable of producing magnitude-9.0 earthquakes and tsunami waves about 100 feet ...
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.
For example, a fault outside of Kalamazoo was revealed after a 4.2-magnitude earthquake in 2015 — the state's largest since a 4.6-magnitude quake along the same fault in Coldwater in 1947.
The northern subduction zone is expanding by rifting while the southern contains a strike slip fault. [7] Seismologists have been studying how the subducting slabs underneath the Mariana island arc are entering the lower mantle and being redirected horizontally, deflecting off the upper to lower mantle transition zone.
