The rare NMSZ (new madrid seismic zone) movement is somewhat expected following the other activity occurring along the edge of the craton.
The fracking operations have all shown heavy movement in the past week, as well as heavy geyser activity at Yellowstone National park. In addition to the aforementioned activity, we also saw multiple dormant volcanoes show movement as well.
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.
