The New Madrid Seismic Zone showed rare larger earthquake activity this morning, April 2, 2015.
A noteworthy 4.0 magnitude earthquake struck at the border of Missouri and Tennessee.
The rare NMSZ (new madrid seismic zone) movement is somewhat expected following the other activity occurring along the edge of the craton.
This past week (7 days) has shown a buildup in seismic pressure coming from the West coast, translating out to multiple earthquakes at locations which normally do not show much movement.
Past 7 days (up to April 2 2015) of 4.0M+ events shows the Fracking operation in California had a 4.1M, dormant Pisgah Craters volcano had a 4.0M in Southern California, 2.7M strikes Dallas TX fracking operation, and a 4.0M strikes the New Madrid.
Information on this 4.0M in Missouri from the USGS:
M4.0 - 3km SSW of Steele, Missouri
