Que nous apprennent les bases de données sur les désastres associés aux séismes ? Réflexions géographique et géohistorique sur la ville d'Esmeraldas (Équateur)

Physio-Géo, 2019
As for the city of Esmeraldas, earthquake-related disasters databases are found limited and poorly consistent. This is all the more surprising that exposure is very high on the active Ecuador-Colombia margin, and strategic oil-related assets stand in or ...

Contrasting stress fields on correlating margins of the South Atlantic [PDF]

, 2015
The “passiveness” of passive continental margins across the globe is currently under debate since several studies have shown that these margins may experience a variety of stress states and undergo significant vertical movement post-breakup.

Electromagnetic study of the active continental margin in northern Chile

Physics of the Earth and Planetary Interiors, 1997
Magnetotelluric and geomagnetic deep sounding measurements were carried out in the magmatic arc and forearc regions of northern Chile between 19.5° and 22°S to study the electrical conductivity structures of this active continental margin. The instruments used covered a very broad period range from 10−4 s to approx.
