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...

2022 Modeling shallow slow slip events along the Hikurangi margin: Insights into their segmentation and the effect of pore-pressure cycling
02 Jul 2022 | Webinars | Contributor(s): Andrea Perez-Silva
Friday July 1, 2022 Andrea Perez-Silva, Victoria University of Wellington Over the last two decades, geodetic observations have revealed slow slip events (SSEs) in most subduction zones worldwide. Of these, SSEs that occur along the shallow (<~15 km depth) portion of the Hikurangi...

2022 Cycles of slow slip events on nonplanar subduction faults and their implications on megathrust earthquakes
11 Jun 2022 | Webinars | Contributor(s): Duo Li
Slow slip and slow earthquakes (SSEs), driven by transient aseismic deformation along the subduction interface, are proposed to affect the initiation of megathrust earthquakes. Prominent examples, as inferred from geodetic and seismic observations, include the 2011 M9.1Tohoku-Oki,, the 2014...

2022 Fault-size dependent fracture energy, seismogenesis, and cascading rupture on multi-scale fault networks
29 May 2022 | Webinars | Contributor(s): Dmitry Garagash
Fracture energy fundamentally affects all aspects of earthquake rupture, including fault seismogenesis. Seismological inferences of fracture energy [1-3] are seen to increase with both slip and the size of fault source. To explain these observations, refs [3-5] invoke co-seismic shear...

2022 Theoretical insights on the rupture arrest of large earthquakes
24 May 2022 | Webinars | Contributor(s): Jean Paul Ampuero
What determines the size of an earthquake? How can we quantify the control of geometric and material heterogeneities on rupture segmentation? I will present recent progress in our theoretical understanding of earthquake rupture arrest, especially for the largest earthquakes. Recent advances in...

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...

Rupture styles emerge in a broad range of rupture styles, from slow-slip events collocated with or without tremors to pulse-like earthquake sequences. Meanwhile, Earthquake catalogs exhibit various recurrence patterns, from periodic and characteristic earthquakes to chaotic sequences with...

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...
