The collapse of Bár arbunga caldera, Iceland

Temporal monitoring of subglacial volcanoes with TanDEM-X — Application to the 2014-2015 eruption within the Bárðarbunga volcanic system, Iceland

Article history: Received 18 September 2015 Received in revised form 1 April 2016 Accepted 8 April 2016 Available online xxxx OnAugust 29, 2014, a lava eruption commenced in theHoluhraun plain, north-east of the Bárðarbunga caldera in Iceland. The eruption ended on February 27, 2015, thus lasting for a period of about 6 months. During these months the magma chamber below the caldera gradually d...

Post-eruptive flooding of Santorini caldera and implications for tsunami generation

Caldera-forming eruptions of island volcanoes generate tsunamis by the interaction of different eruptive phenomena with the sea. Such tsunamis are a major hazard, but forward models of their impacts are limited by poor understanding of source mechanisms. The caldera-forming eruption of Santorini in the Late Bronze Age is known to have been tsunamigenic, and caldera collapse has been proposed as...

Caldera rim collapse: A hidden volcanic hazard

Following the emblematic fl ank collapse of Mount St Helens in 1981, numerous models of flank sliding have been proposed. These models have allowed to largely improve the understanding of mechanisms involved in such landslides, which represent a tremendous risk for populations living around volcanoes. In this article, a new mode of landslide formation, related to buried calderas, is described. ...
