Evidence for Caribbean plate subduction in southern Costa Rica
(2023)
Nestled between the Cocos, Nazca, Caribbean, and South American plates, the Panama
microplate represents an area of rapidly evolving tectonics throughout the past ∼10 m.y. Past
and current studies have observed a notable ...
Seismic anisotropy in southern Costa Rica confirms upper mantle flow from the Pacific to the Caribbean
(2020-09-04)
Surrounded by subducting slabs and continental keels, the upper mantle of the Pacific is largely prevented from mixing with surrounding areas. One possible outlet is beneath the southern part of the Central American isthmus, ...
A recent tear in subducting plate explains seismicity and upper mantle structure of southern Costa Rica
(2020-11-12)
Past studies of southern Costa Rica have generated a multitude of tectonic scenarios to account for different data sets. Flat slabs, detached slabs, and slab windows have been proposed to address the uplift of the Cordillera ...
