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: 10.1029/2022tc007645
Abstract: The 2016 moment magnitude 7.8 Kaikoura, New Zealand, earthquake occurred at the southern end of the Hikurangi subduction zone where the upper plate above the shallow megathrust is exposed sub‐aerially. As a result, the substantial… read more here.

DOI: 10.1038/s41598-021-00875-6
Abstract: Quaternary deformation in the northern Chile forearc is controlled by trench parallel shortening along reactivated Mesozoic faults. Dextral strikes-slip is expressed in NW–SE striking faults of the Atacama Fault System, and reverse displacement dominates in… read more here.

DOI: 10.1111/jmg.12283
Abstract: To better understand the evolution of deep-seated crust of the Variscan orogen in the Sardinia-Corsica region, we studied garnet-bearing micaschists which were sampled 3 km east and 15 km northeast of Porto Vecchio, south-eastern Corsica.… read more here.

DOI: 10.1785/0120190208
Abstract: Recent earthquakes involving multiple fault ruptures highlight the need to evaluate complex coastal deformation mechanisms, which are important for understanding plate boundary kinematics and seismic and tsunami hazards. We compare ages and uplift of the… read more here.
