Seismic events location remains then a major challenge. Thanks to waveform modelling, phase identification, and...

..., respectively. We identified 160 discrete seismic events in Farnsworth, Texas and 112 events in Wellington, Kansas that strongly differs from traditional microseismic events. These events are characterized by low frequency content (1-5 Hz) and longer time duration that lasts for 30-60 seconds for data recorded...

... ABSTRACT In this study we examine the ability of statistical models to simulate the magnitudes of seismic events induced by hydraulic fracturing (HF). The motivation for doing so is that, if operators are able to forecast potential event magnitudes, then they may be able to discriminate at an...
