Characterizing the Mechanics of Fracturing from Earthquake Source Parameter and Multiplet Analyses: Application to the Soultz-sous-Forêts Hot Dry Rock site [PDF]

open access: yes, 2005
In 2000 and 2003, two massive hydraulic fracturing experiments were carried out at the European Geothermal Hot Dry Rock site at Soultz-sous-Forêts, France. The objective was to create a dense network of enhanced permeability fractures, which would form

Automatic location of surface-monitored microseismicity with deep learning

open access: yesEarthquake Research Advances
Accurate and rapid determination of source locations is of great significance for surface microseismic monitoring. Traditional methods, such as diffraction stacking, are time-consuming and challenging for real-time monitoring.

Semi-automatic detection and localization of microseismicity induced by a "salt dissolution provoked" cavity collapse [PDF]

open access: yes, 2013
Natural underground cavities, active or abandoned mine workings, particularly when they are shallow, can provoke large scale land subsidence and collapses attended by catastrophic social-economic impacts.

Test and Development of Microseismic Monitoring

open access: yesJournal of Environmental Science and Engineering B
This is a continuation of the article “Ground Monitoring of Microseismic Based on Low Signal-to-Noise Ratio”, and a further summary and reflection after investigating the current situation of microseismic monitoring. It is difficult to provide necessary and sufficient conditions to test the reliability of microseismic monitoring.
