Fine‐Scale Structure and Kinematics of an Active Submarine Strike‐Slip Fault From Micro‐Bathymetric Mapping and Analog Modeling: The North Alfeo Fault Offshore Catania (Eastern Sicily)

Tectonics, Volume 45, Issue 5, May 2026.
Abstract Southern Italy and eastern Sicily have been the site of several destructive historical earthquakes. Here at the junction between the western edge of the Calabrian subduction zone and the Malta Escarpment several strike‐slip faults have been mapped, which may be the surface expression of the lateral slab tear fault and are candidate sources for

Ecology and Seasonal Habitat Use of Northern Bottlenose and Sowerby's Beaked Whales in the Azores

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Beaked whales are among the least known cetaceans, yet they are regularly observed in the Azores, a region recognized as a hotspot for deep‐diving species. In this study, we analyzed opportunistic sightings collected during 1492 whale‐watching trips, including 149 beaked whale encounters, of which 89 were Sowerby's (Mesoplodon bidens) and 31 ...
