Oceanic arcs can provide insight into the processes of crustal growth and crustal structure. In this work, changes in crustal thickness and composition along the Lesser Antilles Arc (LAA) are analysed at 10 islands using receiver function (RF) invers

SUMMARYThe city of San Fernando is the industrial capital of the twin island nation of Trinidad and Tobago in the West Indies. Situated at the west coast, is in close proximity with the Central Range Fault, a major fault crossing the whole island and

Following a month of unrest in June-July 2019 and three months of effusive activity from late December 2020 to March 2021, La Soufrière volcano, St. Vincent, transitioned to a two-week period of explosions on 2021/04/09. During initial unrest, there

We present a high‐resolution 2‐D P‐wave velocity model from a 225‐km‐long active seismic profile, collected over ~60–75 Ma central Atlantic crust. The profile crosses five ridge segments separated by a transform and three nontransform off

Seismic anisotropy in and beneath the subducting slabs of the Antilles is investigated using observations of shear-wave splitting. We use a combination of teleseismic and local events recorded at three-component broadband seismic stations on every ma
