Imaggeo on Mondays: Hot and cold – how ash influences glacial landscapes

This week’s Imaggeo on Mondays is brought to you by Joanna Nield, a lecturer in physical geography at the University of Southampton. Nield explains how volcanic eruptions can impact glaciers and how ash fall can both accelerate and slow down glacial melt… This photo was taken at Fjallsjökull, Iceland in July 2011, shortly after the eruption of Grímsvötn volcano (21 – 30 May 2011).  The Gríms ...[Read More]

Call for abstracts: The 9th Alexander von Humboldt Conference

The Alexander von Humboldt Conference is part of the EGU’s Topical Conference Series, and will be taking place in Istanbul, Turkey (24 – 28 March 2014). The aim of the meeting is to open a forum on natural hazard events that have a high impact and a large destructive potential, focussing on the Euro-Mediterranean Region in particular. The theme for the conference can be broken down into nine broad ...[Read More]

Geosciences Column: Getting a handle on glacial lakes

Glacial lake outburst floods (GLOFs) are caused when masses of meltwater are released from behind a glacier moraine. Moraines are piles of unconsolidated debris that have either eroded from the glacier valley or have been deposited by melting glaciers. When they fail, a huge volume of water can be released, threatening populations further down the valley. Moraine failure can be caused by avalanche ...[Read More]

Natural hazards workshop videos are online!

Every year, the EGU host a two day workshop for primary and secondary school teachers during the General Assembly. Geosciences Information For Teachers (GIFT) workshops aim to shorten the time between discovery and textbook, while providing teachers with material that can be used in the classroom. This year, the workshop was on natural hazards, with scientists from the fields of seismology, volcan ...[Read More]
