This study aims to analyze seismotectonic parameters in the form of log E values, b and a values, as well as. The results showed that areas that have a high number of earthquakes due to high seismic activity caused by high levels of rock fragility, but in areas with high amount of earthquake low energy due to low magnitude, earthquakes that have low magnitudes tend to have a return period more frequently, whereas areas that are prone to destructive earthquakes are areas with longer periods of destructive earthquakes with greater magnitude. Seismotectonic parameters indicate that the region that has the highest a value is found in Bantul (2.92), the highest value of b is in Bantul (0.84) and the highest Log E is in Gunungkidul (13.21), while for earthquakes with the highest return period (0.3 months) that is earthquakes with shallow depths (<30 km) with magnitudes <2.
