Imaggeo on Mondays: A fractured relationship – when lava meets ice

The Kuril Island Chain is formed by four active volcanoes: Golovnin, Mendeleev, Tyatya and Smirnov. Stolbchaty Cape, where the Okhotsk Sea meets the coast of Kunashir Island, is not far from Mendeleev Volcano – responsible for the many hot springs in the area. These are fed by seawater and heated as the water comes into contact with magma and hot rocks within the mantle. The picture shows an outcr ...[Read More]

Sussing out sea level rise

Ocean thermal expansion, that is, the increase in water volume due to temperature alone, is relatively well understood – as is the retreat of both mountain glaciers and ice caps. While most models simulate these effectively, there is little understanding of how both the Greenland and Antarctic ice sheets will respond to climate change. This is because the full extent of ice-ocean interactions is n ...[Read More]

Imaggeo on Mondays: An orogenic experience

Picture yourself in the Himalaya mountain belt: millions of years of continental uplift have produced a vast kingdom of towering monoliths, and they continue to grow as the Indian plate pushes further north into the heart of Asia. These dramatic, breath-taking and downright enormous geological structures can be simplified into the following tectonic units: the Leugogranites, the Transhimalaya, the ...[Read More]

Using social networks to respond to earthquakes

Effective responses to natural disasters require the rapid acquisition of information about where has been affected, how many people are in the affected areas and what the magnitude of the damage is. This information is critical in both disaster and emergency rescue management. Indeed, the first three days after the onset of a disaster has been dubbed the “72-hour golden rescue period”, after whic ...[Read More]
