Repeating earthquakes record fault weakening and healing in areas of megathrust postseismic slip
(American Association for the Advancement of Sciences (AAAS), 2020)Repeating earthquakes (REs) rupture the same fault patches at different times allowing temporal variations in the mechanical behavior of specific areas of the fault to be interrogated over the earthquake cycle. We study ... -

Seismogenic zone structure beneath the Nicoya Peninsula, Costa Rica, from three-dimensional local earthquake P- and S-wave tomography
(Geophysical Journal International, 2006)The subduction plate interface along the Nicoya Peninsula, Costa Rica, generates damaging large (Mw > 7.5) earthquakes. We present hypocenters and 3-D seismic velocity models (VP and VP/VS) calculated using simultaneous ... -
Seismogenic zone structure of the southern Middle America Trench, Costa Rica
(Journal of Geophysical Research, 2003-10)The shallow seismogenic portion of subduction zones generates damaging large and great earthquakes. This study provides structural constraints on the seismogenic zone of the Middle America Trench offshore central Costa ... -
