The Ohio Seismic Network (OhioSeis) was founded in 1999; this study was conducted to look in to the possibilities of working with the available data from their online database and to familiarize others with the procedures behind finding magnitudes of earthquakes based on a seismogram. To study these possibilities, the data, the seismogram viewer and magnitude calculation program will be tested for accuracy. To educate those unfamiliar with the Ohio Seismic Network, a walkthrough of the stations will be given and data will be analyzed as an example to help better understand the process that goes with analyzing a seismic record. The goal at the end of the walkthrough is for anyone to be able to step in and calculate the magnitude of any given event available on the database and understand what that calculation means. To test the data of the database, seismograph data will be collected and analyzed using the same methods used by the volunteers who work for Ohioseis. The results of this test will display any possible problems with the data, acquisition process, data manipulation, or calculation process. Data suggest that there are problems within the processes of calculating magnitudes of earthquakes in Ohio, and that more investigation is necessary in order to overcome these inconsistencies.
