We use histories of magma efflux and surface deformation from a continuously operating global positioning system (cGPS) to quantitatively constrain magma transfer within the deep crustal plumbing of the Soufriere Hills Volcano (SHV). Displacement rec

We examine the role of basin-shortening on the development of structural compartments in passive margin basins. A coupled flow-deformation model is used to follow the evolution of an idealized prismatic basin during lateral shortening. This includes

[1] We use time-series of magma efflux and GPS-derived surface deformation observations to constrain the transfer of compressible magma within the crustal plumbing of the Soufriere Hills volcano for three cycles of effusion and pause. Our system mode

[1] Vulcanian explosions with plumes to 12 km occurred at Soufriere Hills volcano (SHV) between July 2008 and January 2009. We report strainmeter and barometric data, featuring quasi-linear strain changes that correlate with explosive evacuation of t

[1] Most inversions of geodetic data for volcanic systems assume homogeneous media. Here we examine the effect of inhomogeneous media using axisymmetric finite element models of Soufriere Hills Volcano (SHV), to show that homogeneous elastic crustal

By the use of convergence-confinement method, three-dimensional problem of tunnel excavation is simulated by an equivalent two-dimensional plane strain analysis. In this method, the evaluation of the convergence occurred before the time support start

Evaluating the rock mass properties is a crucial stage in designing support requirements in the tunnelling projects. A well known approach, based on engineering classification systems, is frequently being used by tunnel designers. In recent years the
