Rock-ice avalanches: 100 million cubic metres at the speed of a fast train

Welcome to the GeoWednesday talk "Rock-ice avalanches: 100 million cubic metres at the speed of a fast train", by Andreas Kääb, Professor of Remote Sensing at the Department of Geosciences, University of Oslo.

Giant rock-ice avalanches are rare but among the largest and least predictable natural hazards in high mountains. The mixture of rock and ice makes these events exceptionally mobile, violent, and far-reaching. While we understand many aspects of these disasters, much remains unknown.

Andreas Kääb has been Professor of Remote Sensing at the Department of Geosciences since 2005. He studies cold regions — especially glaciers, permafrost, snow, and river flow — and the climate change impacts and natural hazards associated with them.

Once a month, researchers at the Department of Geosciences, University of Oslo, will tell about their research and introduce the geociences to a wide audience, from first-year undergraduates, colleagues to interested in general. It is possible to ask questions after the lectures. 

Coffee/tea are served. Everyone is welcome!

The lectures are streamed. You can watch the stream at Realfagsbiblioteket YouTube-channel.
