We adapt the relative polarity method from Shelly et al.(2016) to compute focal mechanisms
for microearthquakes associated with the 2014 hydroshearing stimulation at the Newberry …

In microseismicity analyses, reliable focal mechanisms can typically be obtained for only a
small subset of located events. We address this limitation here, presenting a framework for …

We adapt the PageRank method to define signal‐correlation topology for microearthquakes
at the Newberry Volcano enhanced geothermal systems (EGS) demonstration in central …

Earthquake focal mechanisms are traditionally produced using P‐wave first‐motion
polarities and commonly require well‐recorded seismicity. A recent approach that is less …

We have developed a novel regularized approach to estimate a composite focal mechanism
for microseismic events that share a similar source mechanism. The method operates by …

Earthquake focal mechanisms, determined with P‐wave polarities and S/P amplitude ratios,
are primary data for analyzing fault zone geometry, sense of slip, and the crustal stress field …

We utilized relative polarity measurements and machine learning techniques to better
resolve focal mechanisms and stress orientations considering a catalog of∼ 29,000 …

We calculated high-resolution relative locations and full moment tensors for
microearthquakes that occurred before, during, and following EGS stimulation experiments …

At the Decatur carbon capture and storage site (IL, USA) CO 2 has been injected from 2011–
2014 and from 2017 to present near the base of the Lower Mt. Simon Sandstone saline …

Kansas, like other parts of the central US, has experienced a recent increase in seismicity.
Correlation of these events with brine disposal operations suggests pore fluid pressure …
