The heat seeping from the geothermal area which is part of the Krafla volcanic system in Iceland, ‘powers’ the steaming vent at Hverir (Hverarönd). The area is well known for its mud pots and sulphuric gas fumaroles, complete with pungent eggy smell. Some of the vents are in fact boreholes drilled in the 50’s for sulphur exploration which have been turned into fumaroles, the steam is a resul ...[Read More]

Geotalk is a regular feature highlighting early career researchers and their work. Following the EGU General Assembly, we spoke to João Duarte, the winner of a 2017 Arne Richter Award for Outstanding Early Career Scientists.  João is a pioneer in his field. He has innovatively combined tectonic, marine geology and analogue modelling techniques to further our understanding of subduction initiation ...[Read More]

The forward scattering of sunlight, which is caused by a large number of aerosol particles (moist haze) in Alpine valleys, gives the mountain massifs a rather plastic appearance. The hazy area in the foreground lies above the Koenigsee lake; behind it the Watzmann, Hochkalter, Loferer Steinberge and Wilder Kaiser massifs loom up behind one other to the right of the centre line. Behind them is the ...[Read More]

The interior of this ice cave at the Erebus glacier tongue is cathedral-like. Imagine standing in the cold interior, icy blue stalactites dangling from the cave roof; the sense of awe is overwhelming. Mt. Erbus is the world’s southernmost active volcano on Ross Island, in Antarctica. Winding its way down its lower slopes is Erebus glacier. Projecting out from the coast, a jagged and thin tongue ma ...[Read More]
