A Historical Review of Induced Earthquakes in Texas

This historical overview over earthquakes in different areas of Texas shows empirically that seismic activity has grown in line with the oil and gas production, e. g. with secondary techniques, and accompanying underground waste water disposal. ABSTRACT In Texas, earthquakes have occurred in close association with activities accompanying petroleum production since 1925. Here we develop …

Causal factors for seismicity near Azle, Texas

This investigation found a plausible connection between the series of earthquakes near Azle, Texas, in November 2013 began along a mapped ancient fault system and human activity: Pore-pressure models demonstrated that a combination of brine production and wastewater injection near the fault generated subsurface pressures sufficient to induce earthquakes on near-critically stressed faults. Bibliography: Matthew …

Observations of static Coulomb stress triggering of the November 2011 M5.7 Oklahoma earthquake sequence

Key findings: This research suggests that the M5.7 quake was the largest human-caused earthquake associated with wastewater injection.A human-induced magnitude 5.0 earthquake near Prague, Oklahoma in November 2011 may have triggered the larger M5.7 earthquake less than a day later. Observations of static Coulomb stress triggering of the November 2011 M5.7 Oklahoma earthquake sequence Author(s): …

Potential link between wastewater injection and M5.7 earthquake in Oklahoma

Key findings: Injection-induced earthquakes could be larger and they could occur on much longer timescales than previously thought. Induced earthquakes could be larger than previously thought, since this type of deep waste fluid injection has the potential to unlock tectonic stresses built up over decades.A 5.7 magnitude frackquake near Prague, OK, in 2011 damaged 14 …
