Triggering Mechanism of Earthquakes
Exploration of fault reactivation processes during hydraulic fracturing operations.
• Full moment tensors with uncertainties resolved using MTUQ.
• Foreshocks show +CLVD, indicating tensile opening linked to fluid injection processes.
• Aftershocks show +ISO and +CLVD, suggesting fluid migration and aseismic slip post-failure.
