FractVis: Visualizing Microseismic Events [PDF]

open access: yes, 2013
We present our efforts of applying information visualization techniques to the domain of microseismic monitoring. Microseismic monitoring is a crucial process for a number of tasks related to oil and gas reservoir development, e.g., optimizing hydraulic fracturing operations and heavy-oil stimulation.

Distinct Crustal Structure Across the Alpine Fault, New Zealand: Seismic Imaging of a Through‐Going Vertical Fault Beneath Its Central Section

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The Alpine Fault (Aotearoa New Zealand) is a major plate boundary transform fault, that quasi‐periodically hosts large (M7‐8) to great (M8+) earthquakes. The fault is thought to be segmented with sections rupturing both individually and in combination.

Uncertainty of microseismic sources identification and probabilistic location in underground excavation

open access: yesFrontiers in Earth Science
Microseismic (MS) source location is an integral component of MS technology and essential to understanding the rock failure mechanism and avoiding potential geological hazards in underground rock excavation. However, accurate location remains challenging

Estimating Ice Cover on the Great Lakes Using Seismic Ambient Noise

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Lake ice impacts seismic noise on nearby seismometers, and therefore seismic observations can be used to monitor ice changes. However, the transfer function describing how lake‐microseism noise covaries with ice cover has not been quantified.

Dynamic evolution characteristics and risk assessment of floor microseismic in close repeated mining

open access: yesMeitan kexue jishu
The prevention and control of floor water damage has always been the top priority in coal mine safety. Currently, there is a paucity of research on the prediction and control of water damage during repeated mining activities within closely spaced coal ...

Distributed Lower‐Crustal Flow Beneath the Central Xianshuihe–Xiaojiang Fault System: Reconciling Geodesy and Geology

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract We use recently compiled GNSS velocities across the Zemuhe‐Daliangshan fault zone, part of the central Xianshuihe‐Xiaojiang fault system, to reconcile a long‐standing mismatch between geodetic and geologic slip‐rate estimates. We show that conventional elastic dislocation models yield slip rates and locking depths that conflict with seismic ...

Microseismic monitoring and numerical simulation on the stability of high-steep rock slopes in hydropower engineering

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2015
For high-steep slopes in hydropower engineering, damage can be induced or accumulated due to a series of human or natural activities, including excavation, dam construction, earthquake, rainstorm, rapid rise or drop of water level in the service lifetime

Detection and monitoring of high stress concentration zones induced by coal mining using numerical and microseismic method [PDF]

open access: yes, 2001
Zones of high stress concentration induced by coal mining at a depth of 1250 meters in the Lorraine Collieries are detected and monitored using a combination of numerical and microseismic methods.

.Design of acquisition system of multi-channel microseismic signal

open access: yesGong-kuang zidonghua, 2018
In view of problems of high cost and low universality existed in current acquisition systems of mine microseismic signal, an acquisition system of multi-channel microseismic signal was designed.
