        abstract = {Research on seismotectonic analysis based on earthquake data from
1969-2017 has been successfully carried out. 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 ({\ensuremath{<}}30 km) with magnitudes {\ensuremath{<}}2.}
