  1. Fault strength evolution during the seismic cycle: Insights from the laboratory

    10 Mar 2023 | Contributor(s): John Bedford

    Geophysical evidence suggests that some faults are frictionally strong, in agreement with laboratory measurements of quasi-static frictional strength (μ ≈ 0.6-0.8) for many crustal materials; whereas others studies have found that some faults are weak when compared to laboratory friction...

  2. 2022 Mainshock and aftershock sequence simulations in a nonplanar fault network

    19 May 2022 | Webinars | Contributor(s): So Ozawa, Ryosuke Ando

    Aftershocks seem to be located along the trace of the mainshock fault; however, due to the location error, we do not know their exact location relative to the mainshock fault. Here, we hypothesize that most aftershocks occur on small subsidiary faults instead of the mainshock fault, and they...

  4. 2022 Energy transfer among flow and magnetic fields with different equatorial symmetry during the dipole reversal in a geodynamo simulation

    17 Feb 2022 | Webinars | Contributor(s): Takumi Kera, Hiroaki Matsui, Masaki Matsushima, Yuto Katoh

    The geomagnetic field has reversed its polarity, and some numerical dynamos have suggested that anti-symmetric flow with respect to the equator plays a role in reversals. Olson et al., (2004) suggested that the equatorial antisymmetric flow is temporarily strengthened, and transports a locally...

  10. 2020 Numerical models of lower crustal flow explain Yellowstone's "tectonic parabola"

    07 Oct 2021 | Webinars | Contributor(s): Jonathan Perry-Houts

    Several hypotheses exist for the origin of the seismically active region of high topography surrounding the Yellowstone hotspot track. Among these is the idea that a dense mid-crustal sill has driven viscous lower crust away from the hotspot track, producing crustal thinning/subsidence in the...
