DOI: 10.1002/2017jb014935
Abstract: We develop an approach to calculate earthquake source directivity and rupture velocity for small earthquakes, using the whole source time function rather than just an estimate of the duration. We apply themethod to an aftershock… read more here.

DOI: 10.1785/0120190035
Abstract: The Western Canada sedimentary basin (WCSB) has experienced an increase in seismicity during the last decade due primarily to hydraulic fracturing. Understanding the ground motions of these induced earthquakes is critical to characterize the increase… read more here.

DOI: 10.1785/0220200461
Abstract: In recent years, the Delaware basin of west Texas has seen a sharp rise in earthquake occurrence, driven in large part by increases in unconventional hydrocarbon production. The advent of Texas Seismological Network in 2017… read more here.
