On the relation of earthquake stress drop and ground motion variability

A Oth, H Miyake, D Bindi - Journal of Geophysical Research …, 2017 - Wiley Online Library
One of the key parameters for earthquake source physics is stress drop since it can be
directly linked to the spectral level of ground motion. Stress drop estimates from moment …
