The largest series of quakes in over 200 years have hit the Oklahoma area. The last time this magnitude of tremors was during the New Madrid mega-quakes of 1811-1812.
Specific to the State of Oklahoma, the first earthquake known with its epicenter located within the State’s borders, occurred in September 1918. A series of shocks at El Reno produced only minor effects; the strongest was intensity V on September 10. Objects were thrown from shelves. Other shocks occurred on the next day.
**Notice the scale of strength is measured by “Intensity” not “Magnitude” (see scale below)
Magnitude vs Intensity Scale
1.0 - 3.0 I
3.0 - 3.9 II - III
4.0 - 4.9 IV - V
5.0 - 5.9 VI - VII
6.0 - 6.9 VII - IX
7.0 + VIII

It is yet known if the recent series of M-class flares (including one X-class) is related to this extremely rare, and perhaps prophetic, array of quakes some larger than 5.0 magnitude. Last Friday Nov. 4th, “two” high speed full halo CMEs (coronal mass ejection) were observed by both the LASCO C2 and STEREO spacecraft. One came from sunspot region 1339, the second came from region 1319 occurring on the farside of the Sun near rotation around the eastern limb.
