  • A tremor source on the San Andreas Fault produced an unusual sequence of low-frequency earthquakes until it was disrupted by the 2004 Parkfield earthquake; the peculiar recurrence pattern has now been modelled, showing that such slip behaviour occurs when the tremor asperity size is close to the critical nucleation size of earthquakes.

  • The magnitudes and epicentral locations of earthquakes along the Main Marmara Fault, Türkiye, are governed by fault geometry, such as fault bends, and by rheological barriers like thick sedimentary sequences, according to simulations of 10,000 years of the seismic cycle.

  • The drying out of the Aral Sea has induced flow of the relatively weak asthenosphere beneath, demonstrating that human activity can influence mantle dynamics, according to numerical simulations of ground uplift measured by radar interferometry.

  • Although the surface deformation of tectonic plate boundaries is well determined by geological and geodetic measurements, the pattern of flow below the lithosphere remains poorly constrained. Here, the author finds that major earthquakes in California have occurred above the regions of current plastic strain accumulation in the mantle.

  • Large subduction zone earthquakes like the M 9.0 Tohoku earthquake of 2011 are followed by transient surface deformation. Here, the authors show this to be caused by rapid flow taking place in the asthenosphere due to temporarily decreased viscosity because of coseismic stress.

  • The aperiodic and variable nature of ruptures and aftershocks on the Himalayan megathrust is explained by the presence of a ramp structure in the middle of the seismogenic zone rather than a flat geometry, according to seismic cycle simulations

  • The rheology of the upper mantle is key to understanding how plate tectonics may evolve. Here, using GPS and tide-gauge measurements along the Sumatran subduction zone, the authors’ show that a bi-viscous rheology model is needed to explain the stress and strain evolution of the upper mantle following earthquakes.

  • Continental underthrusting, delamination rollback and lateral crustal extrusion drive the kinematics of the India-Eurasia collision zone, according to a kinematic model which maps the 3-dimensional plastic strain below the Tibetan Plateau using geodetic data.
