Tiny movements in Earth's outermost layer may provide a Rosetta Stone for deciphering the physics and warning signs of big quakes. New algorithms that work a little like human vision are now detecting these long-hidden microquakes in the growing mountain of seismic data.
Simple actions can dramatically improve a person's chances of surviving a landslide, according to records from 38 landslides in the US and around the world. People who survived landslides tended to show key behaviors such as being aware of the risk, moving to higher ground, and making noise if buried.
Current understanding is that the chemical composition of the Earth's mantle is relatively homogeneous. But experiments conducted by ETH researchers now show that this view is too simplistic. Their results solve a key problem facing the geosciences - and raise some new questions.
Earth's magnetic fields typically switch every 200 to 300 millennia. Yet, the planet has remained steady for more than twice that now, with the last magnetic reversal occurring about 773,000 years ago. A team of researchers based in Japan now has a better understanding of the geophysical events leading up to the switch and how Earth has responded since then.
Geological investigations of low-temperature young deposits on the Styrian Erzberg provide paleoclimatology with new data on the earth's history and its development.
Natural diamonds can form through low pressure and temperature geological processes on Earth, as stated in an article published in the journal Geochemical Perspectives Letters.
An international simulation study by scientists from the US, Australia, and Germany, shows that alternative explanatory models such as asteroid impacts do not generate sufficiently large magnetic fields.
In drought prone Australia, it's largest river, the Murray is known to suffer acidification in its estuary in South Australia. For the first time a study has married geomorphology and environmental chemistry to gain a better understanding of how the lakes formed - and how they should be managed.
Ocean waves represent an abundant source of renewable energy. But to best use this natural resource, wave-energy converters need to be capable of physically handling ocean waves of different strengths without capsizing.
Scientists at The University of Tokyo used computer simulations and a two-state mathematical model to analyze previous data on water and predicted the location of a liquid-liquid critical point in supercooled water. This work may help better understand the unusual properties of water that allow life to exist in its current form on Earth.
