Thanks for contacting us. This 150 mile-long series of faults stretches under five states: Illinois, Missouri, Arkansas, Tennessee and Kentucky, and is responsible for four of the largest earthquakes in the history of the United States, which took place over three months from December 1811 and February 1812. the Cascadia Subduction Zone last ruptured, That Trade War With China Is Finally Netting Some Good at Home. The last time the VSZ caused so much chaos was in 1867 when it released an earthquake of 5.6-magnitude — the strongest in Virginia’s history. Red circles indicate earthquakes that occurred from 1974 to 2002 with magnitudes larger than 2.5. Running through Pennsylvania, New Jersey, and New York, the Ramapo has remained quiet for about 200 years. If we’re talking sheer magnitude, the largest recorded earthquake on North American soil hit Alaska on November 3, 2002. Renewed faulting occurred during the Devonian Period in response to the Acadian orogeny in the east. “We’ve had magnitude 5 earthquakes - could be up to magnitude 6,” said Larson, who said his talk was inspired by the facts, and the fiction, behind last summer's blockbuster hit San Andreas. On average, Southern California has seen big quakes every 110 to 140 years, based on records of past earthquakes and studies of earthquake faults. Like the fault lines they stem from, earthquakes are often little thought of until they actually happen. The New Madrid Seismic Zone (NMSZ) is a 150-mile long fault zone spanning four states in the Midwestern United States (see Figure 1). Over 2.4 million people live within close proximity to the fault today, not to mention the key infrastructure developments, including a major public transit system and the Caldecott Tunnel that run precariously through the fault. The epicenter of the zone is located just west and northwest of Memphis, Tennessee. Jump to Navigation St. Louis Area Earthquake Hazards Mapping Project.

State of Illinois Coronavirus Response Site. Running for nearly 74 miles through cities including Fremont, Hayward, Oakland, Berkeley, and Richmond, the Hayward Fault has the potential to wreak more havoc than most California faults. Between 1811 and 1812, four catastrophic earthquakes with magnitude estimates greater than 7.0 occurred during a three-month period. Specifically, there was widespread normal faulting in southernmost Illinois as a result of rifting, or incomplete breakup of the continent, in the early part of the Cambrian Period. Starting on the Susitna Glacier Thrust Fault, the rupture raced along the Denali Fault System and continued 220 kilometers until it reached the Totschunda Fault, rattling 70 more kilometers. Here a video about the 1964 Alaskan earthquake, also known as the Great Alaskan earthquake and Good Friday earthquake, which occurred at 5:36 PM AST on Good Friday, March 27, 1964. Larson says that one of the biggest misconceptions around earthquakes here is that they don’t happen.
