Well, last year the U.S. Geological Survey released a report that warned that the New Madrid fault zone has the “potential for larger and more powerful quakes than previously thought“, and the USGS also admits that the number of significant earthquakes in the middle part of the country has more than quintupled in recent years. Several destructive shocks occurred on February 7, the last of which equaled or surpassed the magnitude of any previous event. The source of all this anxiety is the fabled New Madrid Seismic Zone. The New Madrid seismic zone is located in the northern part of what has been called the Mississippi embayment. This is the fourth earthquake of the 1811-1812 series. The town of New Madrid was destroyed. The source of all this anxiety is the fabled New Madrid Seismic Zone. Saturday's 3.6 magnitude earthquake near Trumann, Arkansas was a reminder that the New Madrid Seismic Zone is still active. The New Madrid Seismic Zone (/ ˈ m æ d r ɪ d /), sometimes called the New Madrid Fault Line, 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..
The 1811–12 New Madrid earthquakes were an intense intraplate earthquake series beginning with an initial earthquake of moment magnitude 7.5–7.9 on December 16, 1811, followed by a moment magnitude 7.4 aftershock on the same day. The Mississippi embayment is a broad trough filled with marine sedimentary rocks about 50-100 millions years old and river sediments less than 5 millions years old. The USGS reports that the epicenter was west-southwest of New Madrid. According to international insurance giant Swiss Re, if the 1811 and 1812 New Madrid earthquakes were to happen today, the economic losses alone would be in the hundreds of billions of dollars… A series of big shakes — of the sort last seen in 1811 and 1812 — would cause about $300 billion in … Signs of the Last Days® Ministry December 28, 2019 General In the past two weeks, the U.S. Geological Survey has recorded 20 earthquakes along the New Madrid fault line. New Madrid has had: (M1.5 or greater) 0 earthquakes in the past 24 hours 3 earthquakes in the past 7 days; 11 earthquakes in the past 30 days; 195 earthquakes in the past 365 days
The 2018 New Madrid Earthquake was a major earthquake occurring in the year 2018. The first earthquake, a M2.0 tremor, hit 1:40 a.m. CST (7:40 UTC), 7km SSE of New Madrid, Missouri, at a depth of 4.2 miles (6.8 km). The New Madrid Seismic Zone has been rattled by 3 earthquakes in the last 10 hours.
The geologic record of pre-1811 earthquakes reveals that the New Madrid seismic zone has repeatedly produced sequences of major earthquakes, including several of magnitude 7 to 8, over the past 4,500 years.
The infamous New Madrid earthquakes of 1811-1812 rang church bells in Boston, which is 1,200 miles from St. Louis.
