Geophysicist Zachary Eilon developed a new technique to investigate the underwater volcanoes that produce Earth's tectonic plates
Natural and man-made disasters threaten millions of people every year and cause billions of property damage. How much do we know about them? And how can we use that knowledge to save lives and money? A recent report, compiled by the European Commission's Science and Knowledge Service (JRC), seeks to answer these and other questions and to help prepare for the time when disaster strikes.
The 2017 edition of the JRC Atlas of the Human Planet looks at the exposure of people and built-up areas to the six major natural hazards, and its evolution over the last 40 years. The atlas will be presented during the 2017 Global Platform for Disaster Risk Reduction meeting in Cancun, Mexico.
Experiments at Berkeley Lab's Advanced Light Source have helped scientists to solve a mystery of why some rocks can float for years in the ocean, traveling thousands of miles before sinking.
University of Illinois geologist Lijun Liu and his team have created a computer model of tectonic activity so effective that they believe it has potential to predict where earthquakes and volcanoes will occur. Liu, along with doctoral student Jiashun Hu, and Manuele Faccenda from the University of Padua in Italy, published a research paper in the journal of Earth and Planetary Science Letters focusing on the deep mantle and its relationship to plate tectonics.
Evidence from the age of the dinosaurs to today shows that chemical weathering of rocks is less sensitive to global temperature, and may depend on the steepness of the surface. The results call into question the role of rocks in setting our planet's temperature over millions of years.
An international team of researchers led by geoscientists with the Virginia Tech College of Science recently discovered that deep portions of Earth's mantle might be as hot as it was more than 2.5 billion years ago.
In a paper published in Science, researchers report that Titan, like Mars but unlike Earth, has not undergone any active plate tectonics in its recent past. The upheaval of mountains by plate tectonics deflects the paths that rivers take. The team found that this telltale signature was missing from river networks on Mars and Titan.
Researchers have identified three new species of insects encased in Cambay amber dating from over 54 million years ago. In a new study published by PeerJ, researchers describe the new species of fungus gnats, which provide further clues to understanding India's past diversity and geological history.
The rare but spectacular eruptions of supervolcanoes can cause massive destruction and affect climate patterns on a global scale for decades -- and a new study has found that these sites also may experience ongoing, albeit smaller eruptions for tens of thousands of years after.
