Earthquakes are notoriously hard to predict, and so too are the usually less-severe aftershocks that often follow a major seismic event.
Temporal characteristics of some aftershock sequences in Bulgaria
Aftershock Aftershock decay rate secondary Aftershock sequences
2015/9/30
We apply statistical analysis to study the temporal distribution of aftershocks in aftershock sequences of five earthquakes which occurred in Bulgaria. We use the maximum likelihood method to estimate...
Extreme value statistics and thermodynamics of earthquakes: aftershock sequences
Pareto and beta power laws cluster dimension frequency-magnitude regression laws order-statistics indipendence and clustering thermodynamics of aftershocks
2015/9/29
The Gutenberg-Richter magnitude-frequency law takes into account the minimum detectable magnitude, and treats aftershocks as if they were independent and identically distributed random events. A new m...
A statistical study of aftershock sequences
Statistics aftershocks crustal activity earthquake magnitude
2015/8/28
A comprehensive statistical study of the phenomenology of aftershock sequences is made in this paper. The spatial distribution of aftershocks indicates that they are mainly crustal events; however, de...
Faulting mechanism of the Campania–Lucania 1980 earthquake, Italy, from high-resolution, 3D velocity structure, aftershock relocation, fault-plane solutions, and post-seismic deformation modeling
Campania-Lucania 1980 earthquake analyses of the post-seismic data
2015/8/27
This study performs a detailed reconstruction of the rupture mechanism of the 1980 Campania–Lucania (southern Italy) earthquake. This is achieved by relocation of the main event through computation of...
Comparison between low-cost and traditional MEMS accelerometers: a case study from the M7.1 Darfield, New Zealand, aftershock deployment
Seismology Instruments and techniques Ground Motion Seismic Risk
2015/8/27
Recent advances in micro-electro-mechanical systems (MEMS) sensing and distributed computing techniques have enabled the development of low-cost, rapidly deployed dense seismic networks. The Quake-Cat...
Variability of earthquake nucleation in continuum models of rate-and-state faults and implications for aftershock rates
Variability earthquake nucleation continuum models rate-and-state faults implications for aftershock rates
2014/4/8
Using two continuum models of rate-and-state faults, one with a weaker patch and the other with rheological transition from steady state velocity-weakening to velocity-strengthening friction, we simul...
