Microseismic monitoring and analysis of induced seismicity source mechanisms in a retreating room and pillar coal mine in the Eastern United States

Underground Space, 2017
A microseismic monitoring system was installed in an underground room and pillar coal mine in the Eastern United States to analyze the occurrence and characteristics of induced seismicity during the retreat of two panels in the mine.

Characterization of a complex near-surface structure using well logging and passive seismic measurements [PDF]

Solid Earth, 2016
We combine geophysical well logging and passive seismic measurements to characterize the near-surface geology of an area located in Hontomin, Burgos (Spain). This area has some near-surface challenges for a geophysical study.

Deep ductile shear localization facilitates near-orthogonal strike-slip faulting in a thin brittle lithosphere [PDF]

, 2020
Some active fault systems comprise near-orthogonal conjugate strike-slip faults, as highlighted by the 2019 Ridgecrest and the 2012 Indian Ocean earthquake sequences.

Utilizing seismic techniques and dynamic field tests for soil dynamic response prediction in clay soils

Magazine of Civil Engineering
When evaluating the dynamic response of soil, shear modulus is an essential parameter to consider. In most cases, the shear modulus is estimated using the shear wave velocity (Vs) of the soil as observed in field geophysical testing.

Seismological structure of the 1.8 Ga Trans-Hudson Orogen of North America [PDF]

, 2016
Precambrian tectonic processes are debated: what was the nature and scale of orogenic events on the younger, hotter, and more ductile Earth? Northern Hudson Bay records the Paleoproterozoic collision between the Western Churchill and Superior plates—the ∼

Scale-dependence of lithological control on topography: Bedrock channel geometry and catchment morphometry in western Scotland [PDF]

, 2010
We propose that a scale-dependent topographic signature of erodibility arises due to fluvial and glacial erosion acting on different parts of the landscape at different times.
