Bureau researcher and TexNet principal investigator Dr. Alexandros Savvaidis was recently informed by the Journal of Geophysical Research: Solid Earth (JGR) that his October 2019 paper is among the journal’s top 10% most downloaded papers in recent publication history. JGR determines this milestone by reviewing which papers published during a 2-year period receive the most downloads within 12 months of their publication. Dr. Savvaidis’ work has achieved this distinction despite having been published for only about 7 months at the time of writing.

Dr. Savvaidis’ paper, titled “Improving Absolute Earthquake Location in West Texas Using Probabilistic, Proxy Ground-Truth Station Corrections,” discusses his work in improving the accuracy of earthquake location monitoring by statistically associating earthquakes with fracturing activity—a cause of human-induced earthquakes. Known locations of fracturing activity are used as proxy ground-truth events to calculate the seismic network. Accurately determining the location and depth of seismic events is critical to monitoring earthquakes and the threat they pose to public safety and infrastructure.
