how is the transfer of energy as seismic waves related to frequency and magnitude of earthquakes in a region
One of the largest earthquakes was the Magnitude 9.0 earthquake in Japan on March 11, 2011. The Jan 12, 2010 7.0 magnitude Earthquake in Haiti was the deadliest with the most fatalities in last 20 years. Take a look at the USGS Seismicity Maps for worldwide earthquake activity. A large full-scale detailed map is also available. USGS keeps lists of earthquakes by country, region, and year (1990 - present). See URL in related links.
Earthquake intensity is measured on a scale called 'Mercalli Intensity Scale' or more recently 'Modified Mercalli Scale'. The scale quantifies the effects of an earthquake on the Earth's surface, humans, objects of nature, and man-made structures on a scale from I (not felt) to XII (total destruction). An earthquake is graded after collecting data from people who have experienced the earthquake and observing the destruction caused by the earthquake. People often confuse 'Intensity' of an earthquake with its 'magnitude.' An earthquake's magnitude is a measure of the energy released by an earthquake that propagates from it. It is measured by the Richter scale(formerly), or Moment Magnitude Scale. Information about the earthquake is put into an algorithm to assign the earthquake to a scale of 2 or less, to 10.0+ and anything in between. A magnitude of 2 or less is extremely weak, and may not have been felt at all. An earthquake with the magnitude of 10 is extremely massive and would cause mass destruction - there have not been any 10.0 earthquakes recorded yet. Magnitude and Intensity are correlated. Intensity depends on the magnitude, distance between focus and surface, and population density of the region etc. So, an earthquake with more magnitude will have more intensity, given all the conditions remain same. See the Related Links section below for the algorithm.

As of my knowledge cutoff in September 2021, significant earthquakes in Ohio are relatively rare. The largest earthquake in recent history occurred on March 9, 1937, near Anna, Ohio, with a magnitude of 5.4. However, earthquakes of smaller magnitudes do occur occasionally in the region.

5-6 recorded earthquakes have measured 9.0 or higher on the Richter scale. 1960 Valdivia earthquake; Valdivia, Chile; 9.5 magnitude 1964 Alaska earthquake; Prince William Sound, Alaska, USA; 9.2 magnitude 2004 Indian Ocean earthquake; Indian Ocean, Sumatra, Indonesia; 9.1-9.3 magnitude 1952 Kamchatka earthquakes; Kamchatka, Russia (then USSR); 9.0 magnitude 2011 Tohoku earthquake; Pacific Ocean, Tohoku region, Japan; 9.0 magnitude 1833 Sumatra earthquake; Sumatra, Indonesia; 8.8-9.2 magnitude (est.)
A magnitude 7 releases about 1000 times more energy than a magnitude 5, so therefore you need 1000 magnitude 5 earthquakes to release the same energy as 1 magnitude 7.
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.
