Coseismic Frictional Heating With Concomitant Hydrothermal Fluid Circulation Revealed by Rock Magnetic Properties of Fault Rocks From the Rupture of the 2008 Wenchuan Earthquake, China

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Coseismic frictional heating and associated hydrothermal fluid circulation play an essential role in the dynamic weakening of seismic faults. However, temperature rise induced by frictional heating during an earthquake is still difficult to constrain ...

Measuring Impulse-DSI and its Derivatives Via the Isometric Belt Squat: Assessing Relationships with Sprint Ability Among Division 1 Team Sport Athletes

open access: yesInternational Journal of Strength and Conditioning
The dynamic strength index (DSI) is a common athlete profiling tool that has traditionally been derived as the ratio between the peak force in the isometric mid-thigh pull (IMTP) and the countermovement jump (CMJ) to identify ballistic strength deficits.

The isotropic and anisotropic passive seismic tomography for mineral exploration: a case study of Dongchuan copper deposit, China

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources
Conventional metallic mineral exploration has primarily relied on potential field and electromagnetic methods, while reflection-based seismic methods have seen limited application in this field.

A deformation-driven earthquake interaction model for seismicity at Campi Flegrei

open access: yesCommunications Earth & Environment
Since 2005, the Campi Flegrei nested caldera volcano, located about 10 km west of Naples, Italy, has experienced accelerating uplift accompanied by increased seismicity, raising concerns in this densely populated area.

High-Resolution Digital Elevation Modeling from TLS and UAV Campaign Reveals Structural Complexity at the 2014/2015 Holuhraun Eruption Site, Iceland

open access: yesFrontiers in Earth Science, 2017
Fissure eruptions are commonly linked to magma dikes at depth and are associated with elastic and inelastic surface deformation. Elastic deformation is well described by subsidence occurring above the dike plane and uplift and lateral widening occurring ...

New Advance in Land-Controlled-Source Audio-Frequency Magnetotellurics Exploration: Measurement at a Shortened Transmitter–Receiver Offset and Three-Dimensional Inversion

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Ambient noise significantly affects the quality of land-controlled-source audio-frequency magnetotellurics (CSAMT) data. Shortening the transmitter–receiver offset can enhance the raw data signal-to-noise ratios (S/N).

Review of temporal variations of underground medium based on seismic waves

open access: yes地球与行星物理论评
As a vibrant and ever-evolving planet, the Earth has a dynamic evolution process spanning more than a dozen orders of magnitude from seconds (e.g., seismic rupture) to millions of years (e.g., mantle convection).

Subduction Dynamics at the Northwestern Pacific Slab Edge: Constraints of Tomography in Kamchatka

open access: yesCT Lilun yu yingyong yanjiu
Kamchatka is located at the northwestern edge of the Pacific plate. The Pacific slab is subducting into the mantle along the Kamchatka trench. Are there any differences in subduction features near the edge? To answer this question, seismic tomography was
