The Matrix Profile in Seismology: Template Matching of Everything With Everything
JOURNAL OF GEOPHYSICAL RESEARCH: SOLID EARTH
20 february 2024
Nader Shakibay Senobari, Peter M. Shearer, Gareth ...
Template matching has proven to be an effective method for seismic event detection, but is biased toward identifying events similar to previously k...
SKHASH: A Python Package for Computing Earthquake Focal Mechanisms
SEISMOLOGY GENERAL CONTRIBUTION: EARTHQUAKES IV ORAL
seismology | 13 december 2023
Robert Skoumal, Jeanne Hardebeck, Peter M. Shearer...
We introduce a Python package for computing focal mechanism solutions. This algorithm, which we refer to as SKHASH, is largely based on the HASH algor...

Ruptures Often Extend Beyond the Metastable Olivine Wedge for Large Deep Earthquakes
SLOW-TO-FAST EARTHQUAKES FROM SHALLOW TO DEEP: OBSERVATIONS, EXPERIMENTS, AND NUMERICAL MODELING IV POSTER
tectonophysics | 13 december 2023
Zhe Jia, Wenyuan Fan, Wei Mao, Peter M. Shearer
The long-standing mystery of deep earthquake occurrence results from the seemingly prohibitive high temperature and pressure at the 500-700 km depth. ...

TECTONIC SETTING, GEOPHYSICS, SURFACE RUPTURES, AND SIGNIFICANCE OF 6 FEBRUARY 2023 EARTHQUAKE SEQUENCE IN SOUTHERN TÜRKIYE AND NORTHWESTERN SYRIA II POSTER
tectonophysics | 13 december 2023
Zhe Jia, Zeyu Jin, Mathilde Marchandon, Thomas Ulr...
The recent moment magnitude (Mw) 7.8-7.7 earthquake doublet ruptured multiple segments of the East Anatolian Fault system in Turkey and caused heavy d...

Resolving detailed velocity structure near the 660-km discontinuity using S660S waveforms
SEISMOLOGY GENERAL CONTRIBUTION: STRUCTURE V ORAL
seismology | 13 december 2023
Shangqin Hao, Songqiao S. Wei, Peter M. Shearer
SS precursors, the underside shear-wave reflections off discontinuities that arrive before the SS phase, have been widely utilized to image the mantle...

Estimating Earthquake Source Parameters from S-Wave Maximum Amplitudes: Application to the 2019 Ridgecrest Sequence
UNDERSTANDING THE VARIABILITY IN EARTHQUAKE SOURCE PARAMETER MEASUREMENTS II ORAL
seismology | 12 december 2023
Ian Vandevert, Peter M. Shearer, Wenyuan Fan
Earthquakes rupture in complex ways, radiating a wide spectrum of seismic energy. The rupture complexities are reflected in earthquake stress drops. S...

Strong Physical Contrasts Across Two Mid‐Lithosphere Discontinuities Beneath the Northwestern United States: Evidence for Cratonic Mantle Metasomatism
AGU ADVANCES
11 december 2023
Tianze Liu, Emily J. Chin, Peter M. Shearer
Mid‐lithosphere discontinuities are seismic interfaces likely located within the lithospheric mantle of stable cratons, which typically repre...
Seismic source spectral properties of dynamic rupture with a self-similar, self-healing slip pulse
UNDERSTANDING THE VARIABILITY IN EARTHQUAKE SOURCE PARAMETER MEASUREMENTS I POSTER
seismology | 11 december 2023
Yuto Kano, Yoshihiro Kaneko, Peter M. Shearer
Large earthquakes commonly exhibit pulse-like rupture modes, but stress drops of small earthquakes are often estimated from far-field body-wave spectr...
