Seafloor structural observations, Costa Rica accretionary prism
(1996-04-15)By studying seafloor morphology we can make associations between near surface defornation, fluid flow and the overakk structural framework of accretionary prisms. In February, 1994 a DS/RV ALVIN program to the Costa Rica ... -

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 ... -
Short-period volcanic gas precursors to phreatic eruptions: Insights from Poás Volcano, Costa Rica
(Elsevier, 2016-03)Volcanic eruptions involving interaction with water are amongst the most violent and unpredictable geologic phenomena on Earth. Phreatic eruptions are exceptionally difficult to forecast by traditional geophysical techniques. ... -
