Seismic Structure of Cocos and Malpelo Volcanic Ridges

Seismic Structure of Cocos and Malpelo Volcanic Ridges

The Cocos and Malpelo Volcanic Ridges are blocks of thickened oceanic crust thought to be the result of the interaction between the Galapagos hotspot and the Cocos-Nazca Spreading Center during the last 20 m.y. In this work we investigate the seismic structure of these two aseismic ridges along three wide-angle transects acquired during the PAGANINI-1999 experiment.
