The risk of an eruption at Iceland’s Bardarbunga volcano has increased, with signs of “ongoing magma movement”, Iceland’s meteorological office says.
As we are due to visit Iceland in February, this is really exciting. Let’s hope its calmed down nicely for us to see the after effects first hand. This volcano is not a stereotypical composite cone shape, but has a caldera like crater situated under the glacier. As the plates move apart here (constructive plate margin) upwelling magma is often active in the caldera regions such as Bardarbunga. The most damaging impacts of an eruption here would be melting the glacier causing mud flows (lahars) and the impact of the ash ejected into the atmosphere.
