Ghostly traces of massive ancient river revealed

Using zircon crystals, researchers have discovered the route of a massive ancient river that could help find new reservoirs of fossil fuels and suggest how modern rivers might change over time.

More than two thirds of the worlds’ major cities are located in coastal deltas. How they change over time can impact communities that live around them.

Earthquakes, tsunamis, floods – our planet in all its moods

From tomorrow, for nearly two weeks Australia is hosting a huge meeting of earth scientists – many of them flying directly from their work at recent hot spots.

They will be providing the most up-to-date information on the Japanese tsunami, the safety of nuclear installations, the Christchurch earthquake, Cyclone Yasi, the ash clouds and more. They will also be putting all of this in context and reveal the bigger picture about our planet in all its moods.

The conference is Earth on the Edge, the 25th General Assembly of the International Union of Geophysics and Geodesy (IUGG), and it has attracted almost 4,000 delegates from around 100 countries. [continue reading…]

Air, fire, earth and water – understanding our planet in all its moods

In 2011 Australia will hold one of the world’s largest meetings of earth scientists. They will explore all the physical aspects of our planet, from deep in the Earth’s core to our place in space.

Given recent natural disasters—such as the Pakistan floods, Black Saturday bushfires, Hurricane Katrina, the 2004 Boxing Day Tsunami, 2010 Chile earthquake, Iceland’s Eyjafjallajökull volcano—the Earth seems ever more restless and destructive, and the impact on human life and infrastructure is increasingly heavy.

So it is important to understand how the Earth works—which means the 25th General Assembly of the International Union of Geophysics and Geodesy in Melbourne from 28 June to 7 July 2011 will be a focus of attention, not only for the 3,000 delegates expected to attend, but for many others besides.
