Approaches to earthquake scenarios validation using seismic site response
A seismic hazard assessment was carried out for the Catania and Siracusa towns providing a comprehensive re-examination and re-processing of all the available seismic data. The site approach and the seismotectonic one were used and compared. The hazard assessment, using both methods, was performed …

Subduction in an eddy-resolving state estimate of the northeast Atlantic Ocean
Relatively little is known about the role of eddies in controlling subduction in the eastern half of the subtropical gyre. Here, a new tool to study the eastern North Atlantic Ocean is created by combining a regional, eddy-resolving numerical model with observations to produce a state estimate of …

Seismic and magnetic constraints on the structure of upper oceanic crust at fast and slow spreading ridges
… system. This thesis examines the magnetic and seismic structure of the upper crust at two contrasting ridges-the fast spreading East Pacific Rise (EPR) and the slow spreading Mid-Atlantic Ridge (MAR)-to build a more complete understanding about the roles of volcanic emplacement, tectonic …

Subduction dynamics at the middle America trench : new constraints from swath bathymetry, multichannel seismic data, and 10BE
The cosmogenic radionuclide 10Be is a unique tracer of shallow sediment subduction in volcanic arcs. The range in 10Be enrichment in the Central American Volcanic Arc between Guatemala and Costa Rica is not controlled by variations in 10Be concentrations in subducting sediment seaward of the Middle …
