Welcome to UWISpace, The University of the West Indies Institutional Repository for Research and Scholarship

This archive was established by the UWI Libraries to support the dissemination of knowledge by providing open access to the digitally preserved intellectual output of the University. Here we aim to collect together in one place the research and scholarship of members of the UWI community. UWISpace provides a platform for the collection, organisation, access and preservation of scholarly information in digital formats.

Departments and individuals wishing to deposit their research material in the UWISpace archive can email the administrators, or phone (868) 662 2002, Exts. 84419, 82241, 82215 at The Alma Jordan Library, St. Augustine Campus, Trinidad and Tobago.

    Tectonic inversion in the Caribbean-South American plate boundary: GPS geodesy, seismology, and tectonics of the Mw 6.7 22 April 1997 Tobago earthquake
    (American Geophysical Union) Weber, J.C; Geirsson, H; Latchman, J.L; Shaw, K; La Fermina, P; Wdowinski, S; Higgins, M; Churches, C; Norabuena, E
    In this study, we describe this earthquake and related foreshock and aftershock seismicity, derive coseismic offsets using GPS data, and model the fault plane and magnitude of slip for this earthquake.

    Explosive activity of the last 1000 years at La Soufriere, St. Vincent, Lesser Antilles
    (Elsevier) Cole, P.D; Robertson, R.E.A; Fedele, L; Scarpati, C
    The products of explosive activity of La Soufrière volcano on the island of St Vincent over the last 1000 years are described. Dates for the different eruptions were determined using information from contemporary accounts, fieldwork and radiocarbon dating. Scoria-flow type pyroclastic density currents (PDCs) dominate the products of both the historical eruptions (1979, 1902–03, 1718/1812 CE) and prehistoric eruptions (~1580 and 1440 CE) with subordinate fallout components associated with several eruptions. Radiocarbon dating shows that these six eruptions define a crude cyclicity with repose periods ranging between 77 and ~140 years and systematically decreasing in more recent times.

    An overview of lava dome evolution, dome collapse and cyclicity at Soufrière Hills Volcano, Montserrat, 2005–2007.
    (American Geophysical Union) Loughlin, S. C; Luckett, R; Ryan, G; Christopher, T; Hards, V; De Angelis, S; Jones, L; Strutt, M
    The third episode of lava dome growth at Soufrière Hills Volcano, Montserrat was characterised by higher average magma discharge rates than either previous dome growth episode at this volcano and yet fewer collapses. During sustained dome growth at moderate-high average rates (>6 m3/s), we identified 2–6 week discharge pulses that each supplied c.20 Mm3 magma from depth. Our observations are consistent with some existing models but we explain discrepancies by a combination of higher volatile contents and higher ascent rates. Cycles of c. 11–16 days were evident in rockfall, LP rockfall and shallow LP earthquake counts related to dome growth and degassing. We speculate that degassing at the conduit margins together with stick-slip conduit flow may drive these cycles.
