There are are a great number of very small earthquakes in Oklahoma. In the past 30 days, there have been 162 earthquakes in the northern Oklahoma/southern Kansas region with an average magnitude of about 2.9 and a maximum magnitude of 4.5.
These may be related to hydraulic fracturing to extract oil and natural gas.
Cities in the US that have experienced the most earthquakes include Anchorage, Alaska; Oklahoma City, Oklahoma; and San Francisco, California. These cities are located in regions with higher seismic activity.
Oklahoma is located entirely on the North American Plate well away from any plate boundaries. The earthquakes that have been striking Oklahoma are intraplate earthquakes associated with stresses and faults in the interior of the plate.

Oklahoma has had more then 50 small earthquakes in 2010, most within 50 miles of Oklahoma City, OK.
Some places in India that have had earthquakes are Anjar, Bhuj, Dhubri, and Kangra. Delhi is right on three different earthquake fault lines and the city has experienced many earthquakes.
In recent years, Oklahoma has been experiencing hundreds of felt earthquakes per year. This increase in seismic activity has been linked to human activities such as wastewater injection from oil and gas operations.
Christchurch, New Zealand has experienced several significant earthquakes, with the most notable being the Canterbury Earthquake sequence in 2010 and 2011. These earthquakes caused widespread damage and loss of life in the region.
Just about everywhere on Earth can have earthquakes. Some locations are more known for it than others, but it turns out that one of the largest earthquakes ever in the United States was in Missouri, a location not particularly noted for being earthquake-prone. Anywhere there's a fault, there can be earthquakes. The recent (November 2011) Oklahoma quakes occurred along the Wilzetta fault.
Most days Oklahoma does not get any tornadoes. However, Oklahoma usually has at least a few days each year with several tornadoes, and occasionally more. In some outbreaks Oklahoma has experienced more than 50 tornadoes in one day.
Haiti has experienced multiple earthquakes throughout its history. One of the most devastating earthquakes occurred in 2010, with a magnitude of 7.0, resulting in significant loss of life and infrastructure damage. Haiti continues to be seismically active, with smaller earthquakes occurring periodically.
In 2011, Tulsa, Oklahoma experienced over 100-degree temperatures on 47 days.
In 2017, Georgia experienced a total of 15 recorded earthquakes. The most significant of these was a magnitude 4.0 quake that occurred on January 9. Most of the seismic activity in the state was minor, with many tremors not felt by the general population.
