New University of Washington research to be published in Geophysical Research Letters shows that the lunar forces affect the amount of rain - though very slightly. "As far as I know, this is the first...
World’s first double meteor impact found in Sweden
For the first time ever, Swedish scientists have discovered a double meteor impact from a fall that occurred hundreds of millions of years ago. Two meteoritic craters were found in just 16 kilometers ...
Meteor over Loch Ness: This is how the photographer captured the breath-taking picture
This stunning image of a shooting star is what award-winning photographs are made of – but the man behind the lens said capturing the sight was an "absolute fluke". John Alasdair Macdonald, a tour gui...
Italy's Etna Unleashes A Short But Spectacular Eruption
AFTER WHAT HAS been a quiet 2015, Etna saw one of its first paroxysms of the year. Over the last few weeks, the Voragina crater on Etna has been restless, with low level Strombolian activity that was ...
New Anti-Seismic Brick Improves Response Of Buildings To Earthquakes
Sisbrick is a new class of earthquake-resistant building materials that seismically isolates partition walls from the main building structure, significantly reducing the tension between these two elem...
Earth Not Due For A Geomagnetic Flip In The Near Future
The intensity of Earth’s geomagnetic field has been dropping for the past 200 years, at a rate that some scientists suspect may cause the field to bottom out in 2,000 years, temporarily leaving the pl...
History of geophysics
The historical development of geophysics has been motivated by two factors. One of these is the research curiosity of humankind related to Planet Earth and its several components, its events and its p...
