Where a summer eruption impacts SWRF this leads to a reduction in runoff which is not consistent with the formation of an ETV (Table1; Supplementary Fig.3). However, for runoff simulations driven by volcanically forced climate but with SWRF unchanged (i.e., if ashfall onto the ice sheet ...
Indirect evidence suggests that volcanic activity occurring beneath the West Antarctic ice sheet influences ice flow and sheet stability. However, only volcanoes that protrude through the ice sheet and those inferred from geophysical techniques have been mapped so far. Here we analyse radar data from ...
The parasol effect of volcanic dust and aerosol caused by volcanic eruption results in the deepening and strengthening of the Arctic vortex system, thus stimulating or strengthening the Arctic Oscillation (AO). Three of the strongest AOs in more than a c
Histograms of inter-eruption times Δt approach normality when a logarithmic transformation is applied: $$ \\\log (\\\Delta t + a) $$ The additive term a appears to be associated with the strength of volcanic activity. No significant periodicities at the 95% level can be found in the er...

An emergency vehicle is stationed Saturday on a road leading to volcanic activity between Hagafell and Stóri-Skógfell, Iceland. (Marco di Marco / Associated Press) Share GRINDAVIK, Iceland —Lava from a volcanic eruption in Iceland flowed Sunday toward defenses around th...
The volcanic activity that produces lava flows is known as the effusive eruption type, and this explosive type produces fragmented material, such as pyroclastic flows [1]. The sizes or scales of explosive volcanic eruptions are determined by the volcanic explosion index (VEI) [2]. The VEI measu...
The first eruption in the Reykjanes Peninsula in about 800 years is not expected to threaten any population centers, but it does provide a unique opportunity to study the geologic mysteries of the region.
Recently, images of eruption clouds have been well and frequently returned by artificial satellites such as NOAA, LANDSAT and GOES. Orbit satellites have a high resolution of images, but time intervals to get images are rather long for detection of on-going eruptive activities. Resolution of geosy...
