Regional Seismic Wavefield Propagation [PDF]

open access: yes, 2004
Through the examination of local and regional seismic waveform data the crust and upper mantle of southern California are investigated. Using local and regional seismic phases such as Pn, Sn, PL, and surface waves, seismic wave velocities of interesting

Seismic hazard maps of Peshawar District for various return periods [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2020
Probabilistic seismic hazard analysis of Peshawar District has been performed for a grid size of 0.01∘. The seismic sources for the target location are defined as the area polygon with uniform seismicity.

Slip distributions on active normal faults measured from LiDAR and field mapping of geomorphic offsets: an example from L'Aquila, Italy, and implications for modelling seismic moment release [PDF]

open access: yes, 2015
Surface slip distributions for an active normal fault in central Italy have been measured using terrestrial laser scanning (TLS), in order to assess the impact of changes in fault orientation and kinematics when modelling subsurface slip distributions ...

Probabilistic Seismic Hazard Analysis

open access: yes, 1988
Abstract : The NRC Committee on Seismology established the Panel on Seismic Hazard Analysis to assess methodologies. The panel concentrated on the probabilistic method but also examined alternatives. The panel's discussions included a review of the extensive hazard analyses for the eastern United States by the Electric Power Research Institute and ...

The influence of aftershocks on seismic hazard analysis: a case study from Xichang and the surrounding areas [PDF]

open access: yesNatural Hazards and Earth System Sciences
In some instances, a strong aftershock can cause more damage than the mainshock. Ignoring the influence of aftershocks may lead to the underestimation of the seismic hazard of some areas.
