Towards using seismic anisotropy to interpret ductile deformation in mafic lower crust [PDF]
, 2008 The lower crust forms an important geodynamic control in continental tectonics and the communication and coupling of kinematics between surface and deep-Earth processes.

Seismic anisotropy in siliciclastic reservoir rocks [PDF]
, 2006 The interpretation of geophysical field measurements of seismic anisotropy is presently limited by our knowledge of the controls of the elastic anisotropy of sedimentary rocks in the subsurface. Traditionally, laboratory ultrasonic velocity measurements

Geotechnical design with apparent seismic safety factors well-bellow 1 [PDF]
, 2014 The paper demonstrates that whereas often in seismic geotechnical design it is not realistically feasible to design with ample factor of safety against failure as is done in static design, an "engineering" apparent seismic factor of safety less than 1 ...

Regional Seismic Wavefield Propagation [PDF]
, 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

Heliogeodynamics and seismicity in Pribaikalie
Геодинамика и тектонофизика, 2018 The field of earthquake epicentres of Pribaikalie (Russia) is reconstructed from the data of historical and instrumental monitoring of earthquakes. The analysis shows that seismic events in the study area are distributed irregularly in space and time ...

Post-seismic relaxation from geodetic and seismic data
Geodesy and Geodynamics, 2017 We have examined the aftershock sequence and the post-seismic deformation process of the Parkfield earthquake (2004, M = 6, California, USA) source area using GPS data.

Seismic Performance Evaluation of Retrofitted Bridge by Isolation Bearings
The Baltic Journal of Road and Bridge Engineering, 2009 The seismic performance evaluation and retrofit process are very important in existing bridges. If the result is not appropriate, then retrofit process are required.
