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: 10.1029/2022tc007645
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: 10.1029/2023tc007810
Abstract: Ultrahigh‐pressure (UHP) rocks in North‐East Greenland lie within a larger region of high‐pressure Laurentian crust formed in the overthickened upper plate of the collision with Baltica. Coesite‐bearing zircon dates UHP metamorphism to 365–350 Ma, which… 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.

Spatial and Temporal Clustering of Large Earthquakes on Upper-Plate and Subduction Thrust Faults Along the Southern Hikurangi Subduction Margin, Aotearoa-New Zealand

DOI: 10.1785/0120240246
Abstract: Large (≥Mw 6.5) earthquakes recorded in active fault systems are commonly clustered in space and time, which presents challenges for time-dependent seismic hazard modeling. We investigate the spatial and temporal clustering of earthquakes in the last… read more here.
