In April of 2012, two engineers from UNAVCO conducted a maintenance trip to the Island of Montserrat to service four stations that house continuous GPS systems and borehole strain meters. These four stations were originally installed on the island between 2002 and 2004 as part of the Caribbean Andesite Lava Island Precision Seismo-geodetic Observatory (CALIPSO) project. The instrumentation power systems and data communication infrastructure at these stations has continually been upgraded over the life of this project. While on the island, the UNAVCO engineers also installed two new continuous GPS stations funded by NASA, including one station in the island’s exclusion zone to the southeast of the volcano and another at the extreme northern tip of the island.
Observed deformation of Soufriere Hills Volcano (SHV) provides an excellent example of the broad continuum of temporal and spatial scales of volcanic edifice failure, including:
Examination of these three case studies will shed light on the relative contributions of endogenous as well as exogenous processes that contribute to and eventually result in edifice collapse on all arc volcanoes.
