Computer Programs in Seismology: An Evolving Tool for Instruction and Research
Students must adapt to research‐quality software and use it to develop the deep insight into seismic‐wave excitation and propagation before they can confidently apply the concepts to more sophisticated earth and earthquake models.
Regionalization of crustal coda Q in the continental United States
A contour map of crustal Q/sub 0/ values for the entire United States is presented based on a scattering model to explain the coda waves of local and near regional earthquakes. These coda Q/sub 0/
Attenuation and excitation of three-component ground motion in southern California
Abstract Ground motion attenuation with distance and the variation of excitation with magnitude are parameterized using three-component, 0.25 to 5.0-Hz earthquake ground motions recorded in the
A Student’s Guide to and Review of Moment Tensors
A review of a moment tensor for describing a general seismic point source is presented to show a second order moment tensor can be related to simpler seismic source descriptions such as centers of
Imaging the Upper Crust of the Korean Peninsula by Surface-Wave Tomography
Cross correlation of seismic-background motions (Campillo and Paul, 2003; Shapiro et al. , 2005) is applied to observations from the Korean Meteorological Administration seismic network to estimate
Regional Moment Tensors of the 2009 L'Aquila Earthquake Sequence
Broadband waveform inversion of ground velocities in the 0.02–0.10 Hz frequency band is successfully applied to 181 earthquakes with M L≥3 of the April 2009 L’Aquila, Italy, earthquake sequence. This
Ground-Motion Scaling in the Apennines (Italy)
Regressions over a data set of broadband seismograms are performed to quantify the attenuation of the ground motion in the Apennines (Italy), in the 0.25–5.0 Hz frequency band. The data set used in
Far‐field pressurization likely caused one of the largest injection induced earthquakes by reactivating a large preexisting basement fault structure
The Mw 5.1 Fairview, Oklahoma, earthquake on 13 February 2016 and its associated seismicity produced the largest moment release in the central and eastern United States since the 2011 Mw 5.7 Prague,
Earthquake hypocenters and focal mechanisms in central Oklahoma reveal a complex system of reactivated subsurface strike‐slip faulting
The sharp increase in seismicity over a broad region of central Oklahoma has raised concern regarding the source of the activity and its potential hazard to local communities and energy industry
Characteristics of the Ground Motion in Northeastern Italy
A large data set of ground-velocity time histories from earthquakes that occurred in Friuli-Venezia Giulia (northeastern Italy) was used to define regional predictive relationships for ground motion,
