New Insights into the Emplacement Dynamics of Volcanic Island Landslides [PDF]
Volcanic islands form the highest topographic structures on Earth and are the sites of some of the planet's largest landslides. These landslides can rapidly mobilize hundreds of cubic kilometers of rock and sediment, and potentially generate destructive ...

Observation of sulphate aerosols and SO2 from volcanic eruptions using data from the Atmospheric Chemistry Experiment (ACE) [PDF]
Infrared spectra measured by the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) on board of the SCISAT satellite were used to analyse the temporal and spatial evolution of volcanic aerosols from the Kasatochi (August 2008 ...

Palaeoproterozoic mafic and intermediate metavolcanic rocks in the Turku area, SW Finland [PDF]
Twenty two samples were analysed from mafic and intermediate volcanic rocks from the Turku area along ~60 km long north-south geotraverse. Geographically and lithologically the samples were divided into the Pargas, Turku and Vahto groups.

Upper crustal structure of an active volcano from refraction/reflection tomography, Montserrat, Lesser Antilles [PDF]
To better understand the volcanic phenomena acting on Montserrat, the SEA-CALIPSO seis-mic experiment (Seismic Experiment with Airgun-source – Caribbean Andesitic Lava Island Precision Seismo-geodetic Observatory) was conducted in 2007 December with the ...

Climatic control on the location of continental volcanic arcs
Orogens and volcanic arcs at continental plate margins are primary surface expressions of convergent plate tectonics. Although it is established that climate affects the shape, size, and architecture of orogens via orographic erosion gradients, the ascent of magma through the crust and location of volcanoes along magmatic arcs have been considered ...
