Stress buildup in the Himalaya [PDF]
, 2004 The seismic cycle on a major fault involves long periods of elastic strain and stress accumulation, driven by aseismic ductile deformation at depth, ultimately released by sudden fault slip events. Coseismic slip distributions are generally heterogeneous

Research on microseismic event imaging based on waveform clustering analysis
矿业科学学报, 2022 The quality of microseismic data greatly affects the accuracy of the source location results, especially in surface microseismic data where the first arrivals of P waves and S waves are not obvious or the low signal-to-noise ratio signals are difficult ...

Electrical structure of the Himalaya of Central Nepal: high conductivity around the mid-crustal ramp along the MHT [PDF]
, 1999 Twelve broadband magnetotelluric (MT) soundings were performed across the Himalaya of Central Nepal in 1996 in order to determine the electrical structure of the crust and its relation to geological structures and active tectonics.

Applied Sciences, 2023 Based on the relationship between rockburst and microseismic event indicators, this study proposes that the risk of rockburst in mine working faces, roadways, and even the entire mine should be studied through the “double high” risk evaluation of ...

The origin of deep ocean microseisms in the North Atlantic Ocean [PDF]
, 2008 Oceanic microseisms are small oscillations of the ground, in the frequency range of 0.05–0.3 Hz, associated with the occurrence of energetic ocean waves of half the corresponding frequency.

Tracking cave shape development with microseismic data [PDF]
Proceedings of the Fourth International Symposium on Block and Sublevel Caving, 2018 Microseismic monitoring is routinely used by block and panel caving mines worldwide to track cave shape development. The standard practice is to use the cloud of seismic event locations as a proxy for cave growth below. Careful seismic sensor array planning overcomes problems with event location reliability due to seismicray bending around the unknown ...

Characterization of the seismic environment at the Sanford Underground Laboratory, South Dakota [PDF]
, 2010 An array of seismometers is being developed at the Sanford Underground Laboratory, the former Homestake mine, in South Dakota to study the properties of underground seismic fields and Newtonian noise, and to investigate the possible advantages of ...

Locating microseismic events using borehole data
Geophysical Prospecting, 2013 ABSTRACTConstraining microseismic hypocentres in and around hydrocarbon reservoirs and their overburdens is essential for the monitoring of deformation related to hydraulic fracturing, production and injection and the assessment of reservoir security for CO2 and wastewater storage. Microseismic monitoring in hydrocarbon reservoirs can be achieved via a

Research on automatic picking of microseismic first arrival
Gong-kuang zidonghua, 2020 Accurate picking of the first arrival of microseisms is the prerequisite for the estimation of source location. The traditional manual picking method is inefficient and time-consuming.
