Long-term monitoring of the ocean, for instance its seismic activity, remains a technical and a financial challenge. Despite technological advances in reducing the size and consumption of electronic components, in providing powerful energy through Lithium batteries, and in reducing the size of sensors, the new generation of stand-alone...

Dans des zones de subduction, 80/100 de l'énergie sismique est libérée en mer, parfois à proximité de côtes très peuplées comme sur le pourtour de l'océan Pacifique. D'où l'intérêt de mesurer précisément l'activité sismique dans ces zones vulnérables.

We describe the deep structure of the south Colombian-northern Ecuador convergent margin using travel time inversion of wide-angle seismic data recently collected offshore. The margin appears segmented into three contrasting zones. In the North Zone, affected by four great subduction earthquakes during the 20th century, normal oceanic crust...
