DOI: 10.1016/j.epsl.2019.05.016
Abstract: Abstract How does deformation after an earthquake affect megathrust stresses? Five years of surface velocities following the 2012 moment magnitude 7.6 Nicoya, Costa Rica earthquake uniquely capture the lithospheric recovery. During a four-year period, seaward… read more here.

DOI: 10.1029/2022gl102191
Abstract: Subducting seamounts are recognized as one of the key features influencing megathrust earthquakes. However, whether they trigger or arrest ruptures remains debated. Here, we use analog models to study the influence of a single seamount… read more here.

DOI: 10.1038/s41561-017-0013-4
Abstract: The 2011 Tōhoku-Oki earthquake revealed that co-seismic displacement along the plate boundary megathrust can propagate to the trench. Co-seismic slip to the trench amplifies hazards at subduction zones, so its historical occurrence should also be… read more here.

DOI: 10.1126/science.aan3120
Abstract: Eight slow-slip events over 6 years accommodated up to 50% of the fault slip on the Nankai megathrust. Silently taking up the slack Megathrust earthquakes occur when locked subduction zone faults suddenly slip, unleashing shaking… read more here.

DOI: 10.1144/qjegh2020-023
Abstract: Landslides represent the most frequent geological hazard in mountainous environments. Most notably, landslides are a major source of fatalities and damage related to strong earthquakes. The main aim of this research is to show through… read more here.
