Stress drops and radiated energies of aftershocks of the 1994 Northridge, California, earthquake [PDF]
Journal of Geophysical Research: Solid Earth, 2003 We study stress levels and radiated energy to infer the rupture characteristics and scaling relationships of aftershocks and other southern California earthquakes. We use empirical Green functions to obtain source time functions for 47 of the larger (M ≥ 4.0) aftershocks of the 1994 Northridge, California earthquake (M6.7).

Historical seismograms for unravelling a mysterious earthquake: The 1907 Sumatra Earthquake [PDF]
, 2010 History of instrumental seismology is short. Seismograms are available only for a little more than 100 years; high-quality seismograms are available only for the last 50 years and the seismological database is very limited in time. To extend the database,

The role of radiation damping in the modeling of repeated earthquake events
Annals of Geophysics, 2013 We have investigated the role of the radiation damping term (RDT) on repeated earthquake ruptures by modeling the faulting process through a single one-dimensional analog fault system governed by different constitutive laws.
