This study also examines the shape of the response spectra generated by latestGutenberg–Richter law. Gutenberg–Richter law fitted to the aftershocks of the August 2016 Central Italy earthquake, during the Aug 22 - Sep 1 period. Notice that the linear fit fails at the upper and lower end, due to lack of registered events. Since the recording period is only 10 days, events of magnitude greater than 6 has not yet appeared.

where E is the energy calculated by log 10 E = 11.8 + 1.5M S where energy, E, is expressed in ergs, and M s is the surface wave magnitude. Based on the seismic energy radiated by the earthquake as estimated by integration of digital waveforms. Mh: any: any: N/A: Non-standard magnitude method.
