Deep Underground Science and Engineering, EarlyView.Based on experimental results and theoretical analysis, an established rock damage accumulation model that comprehensively considers the preapplied static load, impact peak value, impact frequency, and impact times. Abstract To study the rock damage mechanism under high static loading and superimposed medium strain rate cyclic impact loading, a series ...

A review on electrokinetically induced seismo-electrics, electro-seismics, and seismo-magnetics for Earth sciences [PDF]
Solid Earth, 2016 The seismo-electromagnetic method (SEM) can be used for non-invasive subsurface exploration. It shows interesting results for detecting fluids such as water, oil, gas, CO2, or ice, and also help to better characterise the subsurface in terms of porosity,

Expected Seismicity and the Seismic Noise Environment of Europa [PDF]
Journal of Geophysical Research: Planets, 2018 AbstractSeismic data will be a vital geophysical constraint on internal structure of Europa if we land instruments on the surface. Quantifying expected seismic activity on Europa both in terms of large, recognizable signals and ambient background noise is important for understanding dynamics of the moon, as well as interpretation of potential future ...

Exploring wave propagation behaviors in rock: A grain‐based perspective on mineral structures
Deep Underground Science and Engineering, EarlyView.This study investigates wave propagation in rock at the grain scale using a grain‐based model, revealing that mineral elastic modulus significantly influences wave attenuation while grain size and distribution have limited effects. A novel peak particle velocity attenuation prediction model is proposed and validated for grain‐scale wave propagation ...

Investigating the TCDP Drill Site Using Deep and Shallow Reflection Seismics
Terrestrial, Atmospheric and Oceanic Sciences, 2007 The 1999 Chi-Chi earthquake (Mw = 7.6), Taiwan, reactivated the 105 km long, NS trending Chelungpu fault causing extraordinary surface ruptures. The distribution of the ruptures was quite heterogeneous with the largest displacement (up to 12 m) occurring

An optimizing microseismic method for rock burst early warning based on mining production process
Deep Underground Science and Engineering, EarlyView.A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.

A repeatable seismic source for tomography at volcanoes
Annals of Geophysics, 1999 One major problem associated with the interpretation of seismic signals on active volcanoes is the lack of knowledge about the internal structure of the volcano.

The stratigraphic setting of continental shelves of southern Italy investigated through seismic stratigraphy: techniques, methodologies and case studies from Campania and Basilicata offshore (southern Tyrrhenian sea) [PDF]
, 2012 The stratigraphic setting of continental shelves of Southern Italy is here studied and discussed through seismo-stratigraphic techniques and methodologies, focussing on case histories located in Campania and Basilicata offshore (Southern Tyrrhenian sea ...

Marine seismics with a pulsed combustion source and Pseudo Noise codes [PDF]
, 2007 There has been an ongoing debate for years of how dangerous seismic surveys are with respect to marine life. Marine seismics is today dominated by airgun technology, where high energy is generated by a release of compressed air into the water.
