The U.S. Geological Survey (click here) gave a 4.5 magnitude designation to an earthquake felt around the Tulsa area Monday afternoon.
According to the USGS, the temblor was recorded at 1:12 p.m. with an epicenter near Crescent in Logan County.
The USGS also had recorded two 3.9 magnitude and a 4.0 magnitude earthquake since Saturday....

There
is also movement along the Caribbean Plate as well. There is several.
It looks fairly obvious to me with movement within the North American
plate enough tension has worked up in the Caribbean plate.
The Oklahoma earthquakes are unrelated to techtonic movement of the plates.

CUSHING, Okla. – In recent years, (click here) earthquakes have become a common occurrence for many residents across Oklahoma.
20 years ago, experts say earthquakes in the Sooner State were few and far between.
Now, it is common for the Oklahoma Geological Survey and the U.S.
Geological Survey to record at least one small quake a day across the
state.
For months, many residents and business owners have been wondering what is behind the increased activity....
Oklahoma is on the North American craton. I worry about the people in Oklahoma and Texas. They have fracked that land for decades and this is the result. The petroleum industry recently put this commercial out that fracking has a long history of success and it is safe. That is a blatant lie. Success, sure, they got stuff out of the ground. Safe, ain't no way.
I am waiting for Oklahoma to become one big quick sand pit. It is probably happening, but, no one hears about it. It is a matter of when not if.
This graphic shows (click here) the thickness (in kilometers) of the North American lithosphere. The blue area is about 250 km thick and composed of a 3-billion-year old craton underlain by younger lithosphere deposited as ocean floor subducted under the continent within the past billion years. The green, yellow and red areas are younger and thinner continental lithosphere added around the margins of the original craton, also by subducting sea floor. The thick broken line indicates the borders of the stable part of the continent.
