GeoTalk, featuring short interviews with geoscientists about their research, continues this month with a Q&A with Dr Olivier Galland (University of Oslo), who tells us about his volcanology research and the importance of outreach in promoting the Earth sciences. If you’d like to suggest a scientist for an interview, please contact Bárbara Ferreira. First, could you introduce yourself and ...[Read More]

The International Association for Promoting Geoethics
As geoscientists we have to consider the human impact of the decisions we make throughout our careers. There are many circumstances that require us to consider and discuss the ethical code of our profession. Developing the necessary soft skills and creating a forum for the discussion of ethical issues is one of the aims of Geology for Global Development. The International Association for Promotin ...[Read More]

Imaggeo on Mondays: The power of ice
There has been a lot of talk about Greenland lately in the context of global climate change. And for good reason. Over 80% of its total surface is covered by ice, the volume of which exceeds 2,850,000 km3 or enough to raise global sea levels by a staggering 7 m if fully melted. The Greenland ice sheet consists of layers of compressed snow from over 100,000 years of snowfall. As a result, ice cores ...[Read More]

Reducing the Risk of Future Disasters
GfGD welcomes the release of the UK Government Office for Science Foresight Report into “Reducing the Risks of Future Disasters: Priorities for decision makers”. The report has been specially commissioned to recognise the growing need for good disaster and risk reduction (DRR) science. The report describes how the growing threat of natural hazards to increasingly vulnerable communities worldwide c ...[Read More]

Geosciences Column: Human-induced changes in the ocean’s salinity and temperature fields
In this month’s Geosciences column, Mona Behl discusses a recent paper on the effects of anthropogenically-induced climate change on the planet’s oceans. A recent study led by scientists at the Scripps Institute of Oceanography, University of California San Diego, suggests that observed changes in ocean salinity are inconsistent with natural climate variations and can be attributed to human ...[Read More]

What can we Learn from the Great Eastern Japan Tsunami?
Over a year and a half on from the Great Eastern Japan Tsunami, and there are still boats lying overturned at the side of roads. Recovering from such a major national catastrophe is a slow process. We hope to be able learn from this tragedy and use it to lower vulnerability to future disasters, both in Japan and around the world’s coastlines. The magnitude 9.0 earthquake on the 11th March 2011 was ...[Read More]

Santiaguito Volcano: Ninety Years and Counting.
Santiaguito volcano, Guatemala, burst into life in 1922 and is now the second longest continuing eruption. It has outlasted both Stromboli (Italy) and Sangay (Ecuador), both erupting since 1934, and is only outdone by Yasur (Vanuatu), which has been erupting at least since 1774, when first visited by Captain Cook. These long-lived eruptions give us an unusual opportunity to use the slowly-extruded ...[Read More]

Imaggeo on Mondays: Blue haze
In this week’s Imaggeo on Mondays, brought to you by the photographer himself, Lukas Hörtnagl (University of Innsbruck, Austria) tells us about the ‘blue haze’ or ‘tule fog’ of California’s Sequoia National Park. I was visiting the United States to attend the Fall Meeting of the American Geophysical Union in December 2011 and decided to stay four more weeks to visit some of the National Parks in C ...[Read More]

Going to This Year’s AGU Meeting?
The American Geophysical Union (AGU) convenes this week for their 45th annual fall meeting – the world’s largest international gathering of Earth scientists. Geoscientists from all around the world will be sharing their latest research and catching up with colleagues from other institutions. There will be plenty of talks relevant to GfGD. We’ve picked our highlights from the sche ...[Read More]

Friday Photo (59): Active Geology – Icelandic Geyser
These two images show an Icelandic geyser when calm (top) and then when ‘erupting’ (Bottom). Historical reports associate increased activity in the geysers with earthquakes. (c) Geology for Global Development
