When NASA's Terra satellite passed over Alaska's erupting Bogoslof Volcano the MODIS instrument aboard captured an image of a large ash plume surrounded by clouds making it appear to be wrapped in white.
Nearly 325,000 people could be affected by an eruption of Cotopaxi, the volcano looming beyond the Ecuadoran capital of Quito, officials said Monday.
A Philippine volcano spewed plumes of ash Tuesday, but volcanologists say the steam-driven explosions do not indicate an imminent violent eruption.
Volcanic ash poses a significant hazard for areas close to volcanoes and for aviation. For example, the 2010 eruption of Eyjafjallajökull, Iceland, clearly demonstrated that even small-to-moderate explosive eruptions, in ...
A Tongan volcano has created a substantial new island since it began erupting last month, spewing out huge volumes of rock and dense ash that has killed nearby vegetation, officials said on Friday.
Satellites are showing clouds of sulphur dioxide from Iceland's restive Bardarbunga volcano.
Following further reports of seismic activity around volcanoes in Iceland, scientists from the University's Department of Meteorology provide comment on the likelihood of an eruption - and how any ash plume could disrupt ...
The Kelut volcano on Indonesia's Java island erupted late last night. While disaster-management authorities are busy on the ground, satellites are tracking the major cloud of ash and sulphur dioxide as it spreads in the atmosphere.
An LMU team has, for the first time, created volcanic lightning in the lab and captured it on film. The new findings may permit rapid characterization of ash clouds released by volcanic eruptions and improve forecasting of ...
Scientists have determined the magnitude of the Mount Gambier volcano eruption 5,000 years ago, and say if a similar eruption occurred again, it could cause widespread damage.
