Induced microseismicity due to mine flooding - Observation, characterisation and relation to mine water rise in the eastern Ruhr area
; ; (2022)
The Floodrisk project takes a muti- and interdisciplinary look on the effects of the rise in mine water level in abandoned coal mine regions in Germany. Such effects are heterogeneous ground uplift, stress changes due to ... -
Injection‐Induced Seismic Moment Release and Laboratory Fault Slip: Implications for Fluid‐Induced Seismicity
; ; ; ; (Geophysical Research Letters, 2020-11-19)
Understanding the relation between injection‐induced seismic moment release and operational parameters is crucial for early identification of possible seismic hazards associated with fluid‐injection projects. We conducted ... -
Laboratory Study on Fluid-Induced Fault Slip Behavior: The Role of Fluid Pressurization Rate
; ; ; ; ; (Geophysical Research Letters, 2020)
Understanding the physical mechanisms governing fluid-induced fault slip is important for improved mitigation of seismic risks associated with large-scale fluid injection. We conducted fluid-induced fault slip experiments ... -
Limited Earthquake Interaction During a Geothermal Hydraulic Stimulation in Helsinki, Finland
; ; ; ; ; ; (Journal of Geophysical Research: Solid Earth, 2022-09-12)
We investigate induced seismicity associated with a hydraulic stimulation campaign performed in 2020 in the 5.8 km deep geothermal OTN‐2 well near Helsinki, Finland as part of the St1 Deep Heat project. A total of 2,875 m3 ... -
Small Magnitude Events Highlight the Correlation Between Hydraulic Fracturing Injection Parameters, Geological Factors, and Earthquake Occurrence
; ; ; ; (Geophysical Research Letters, 2022-11-02)
Hydraulic fracturing (HF) operations are widely associated with induced seismicity in the Western Canadian Sedimentary Basin. This study correlates injection parameters of 12,903 HF stages in the Kiskatinaw area in northeast ... -
Spatio-temporal distribution of induced seismicity in flooded mines in the Ruhr area - interpretation by geomechanical numerical modelling
; ; ; ; (2023)
Induced seismicity during mine flooding is the focus of the FloodRisk project. One of the study areas is the Ruhr area, which is characterised by centuries of intensive coal mining. After the closure of the last mines, ...
