Numerical modelling and geodetic observations improving our understanding about seismic barriers
by Diego Molina (ISTerre, Grenoble, France)
Understanding what controls the maximum size of an earthquake is essential to estimate seismic hazard. Typically, zones promoting seismic rupture arrest along subduction megathrusts have been correlated with the subduction of bathymetric (…)

Megathrust locking encoded in subduction landscapes :
by Bar Oryan (Scripps UCSD, USA)
Locked areas of subduction megathrusts are increasingly found to coincide with landscape features sculpted over hundreds of thousand years, yet the mechanisms that underlie such correlations remain elusive. We show that interseismic locking gradients induce increments of irreversible strain across (…)
