But look how the number of earthquakes in Oklahoma have rapidly increased, since 2008. Where else in the world have the number of earthquakes suddenly skyrocketed like this.
There's a fault right at the Wichita Mountains northwest of Lawton (southeast of Oklahoma City).
What else has happened since 2008?
Quakes on the New Madrid Fault.
Quakes in Arlington-Fairfax (VA), Maryland, Washington DC area.
Why wouldn't a slip fault in Oklahoma slide a bit?
Why are we allowing any company to set off explosives under our earth fracking to get oil..?? Their are consequences for beating our planet up and altering nature....but there is money to be made....sad and sick for future generations.
Just in case anyone here can't see that that could be a problem (I hope there is no one, but never know). Take a look at what happened at the Rocky Mountain Arsenal near Denver in the 1960s. Somebody there got the brilliant idea to just dig a super deep well and dump all the chemical waste down the hole. Yeah, that will work. The problem was that as soon as they started, the Denver Metro Area started getting rocked by a series of unexplained earthquakes, all with an epicenter right in the middle of the arsenal. Natural earthquakes are pretty rare to nonexistent around Denver. To make a long story short, they stopped dumping chemicals down the well, and the earthquakes stopped.

Earthquake History
The series of great earthquakes in the New Madrid, Missouri, region in 1811 - 1812, and a strong earthquake centered in Arkansas (October 22, 1881) were probably felt in the area that is now Oklahoma.
The first earthquake known to have centered in the State 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. On December 27, 1929, another tremor centered in the same area was felt in portions of central and western Oklahoma. Some plaster cracked and at least one chimney fell (intensity VI) at El Reno. In addition, clocks stopped, objects moved, and some reports indicated the walls and floors seemed to sway. In several cities, people rushed from their homes in alarm. The total felt area included about 20,000 square kilometers.
The magnitude 5.5 April 9, 1952, earthquake centered near El Reno affected most of Oklahoma and parts of Arkansas, Iowa, Kansas, Missouri, Nebraska, and Texas. Damage from the 10:30 a.m. CST earthquake was not extensive, but many people in the epicentral area were alarmed, some to near panic. Portions of chimneys fell in El Reno and Ponca City (intensity VII). Bricks loosened from a building wall and tile facing of commercial buildings bulged at Oklahoma City. Also, plate glass windows were shattered in the business district of El Reno. The total damage amounted to several thousand dollars. Aftershocks were felt on April 11, 15, and 16, July 16, and August 14; an earthquake that was felt (IV) at Holdenville and Wewoka on October 7 apparently was unrelated to the April 9th event. Homes and buildings shook and some persons were awakened (V) at El Reno from the April 16th shock, which occurred 5 minutes after midnight. Felt reports were also received from Kingfisher, Oklahoma City, Tulsa, and Union City.
Minor damage to a building foundation and plaster (VI) at Concho resulted from two March 17, 1953, earthquakes about an hour apart. The felt area included Calumet, Edmond, El Reno, Minco, Okarche, Peidmont, and Union City.
On February 16, 1956, a shock at Edmond broke windows and cracked plaster (VI). It was also felt strongly at Guthrie, Oklahoma City, and Pawnee. Southeastern Oklahoma was disturbed by an earthquake on April 2, 1956, that produced thundering, rattling, and bumping noises that were heard by many citizens. Buildings shook and objects fell at Antlers, and many persons were alarmed (V). Minor effects were reported from other nearby towns. On October 30, 1956, an area of about 9,500 square kilometers in northeastern Oklahoma was shaken. The maximum intensity of VII was reported west of Catoosa, where a slippage of the formation caused an oil well to be shut down. Minor damage occurred at Beggs and Tulsa; and isolated felt report was received from Electra, Texas.
A broad area (approximately 31,000 square kilometers) of southwestern Oklahoma and the adjacent portion of Texas was affected by an early morning shock on June 17, 1959. Slight damage, consisting of cracks in plaster, pavement, and a house foundation (VI), occurred at Cache, Duncan, and Lawton. Houses were shaken, buildings swayed, and many persons were alarmed. A smaller earthquake on June 15 was felt by many at Ada and nearby places. Dishes were reported broken (V) and a trembling motion was observed.
On January 10, 1961, a mild shock was felt in Latimer and Pittsburgh Counties in southeastern Oklahoma. Thunderous earth sounds were heard in many places (V); no damage was reported. Another earthquake on April 27, 1961, awakened many (V) at Antlers, Coalgate, Hartshorne, Leflore, McCurtain, Panola, Poteau, Talihina, and Wilburton. Once again, thunderous, deep rumbling earth sounds were heard throughout the area.
An October 14, 1968, earthquake caused minor damage at Durant. Walls cracked, and glass in two structures broke (VI). The press reported that a 5 foot tall advertising stand fell over, and canned goods fell from a rack in a supermarket. Slight foreshocks were felt at Durant on October 10 and 11. Intensity IV effects from the October 14 shock were also noted at Caddo.
A magnitude 4.6 earthquake caused some cracked plaster (V) at Wewoka on May 2, 1969. Intensity V effects were reported at several other towns in the region. The total felt area included approximately 33,700 square kilometers in eastern Oklahoma.

For a list of earthquakes that have occurred since this article was written, use the Earthquake Search.
All those listed and bolded above were prior to any fracking activity in Oklahoma.
Here is a map from the same website detailing the 2 percent chance of a significant earthquake in the US - clearly showing that Oklahoma has an increased risk:
I don't know where you got that information but Oklahoma does not get 20% of all earthquakes happening. California and the Aleutian Islands in Alaska get 10 times more quakes than Oklahoma, they get quakes pretty much every day. Here is a shakemap list of quakes over 3.0 on the richter scale since 1971 up to today. ShakeMap Archive
Check out this map of the world, it shows all earthquakes occuring right now and in recent days, plus other natural disasters, biohazards, nuclear events occuring around the world. RSOE EDIS - Emergency and Disaster Information Service
We had about 5 earthquakes today in my city alone. I woke up to a 5.8 and no one even flinched.
I think before you say that Oklahoma gets 20% of the earthquakes, you should do a google search for "earthquakes today", and unless Oklahoma is getting 50/day, they are not accounting for 20%
A case of different standrds, according to the accompanying link from the U S Geological survey; it lists only about 30 earthquakes over 3.5 on the Richter scale in the past 40 years.
A second source lists a quantity of quakes matching the numbers cited in the original post, but all but a handful under a Richter magnitude of 3 .... thus barely noticeable.
It might be noted that seismographs record many tremors smaller than 3.5, and the effects of oil exploration might be classified as a small quake using that standard.

It's laughable.
I'm just wondering if the locusts are on their way.
