Rock scratches hint at future quakes

The 23-million-year-old bones of the newly-discovered giant, Simbakubwa kutokaafrika, had been left for nearly 40 years in a drawer

Hidden mysteries lie in wait inside Kenya’s fossil treasury

A diagrammatic representation of the Earth in the Archaean showing subducted ocean floor carrying its chemical signature into the deep mantle. The signature which includes water and chlorine is preserved in melt inclusions contained within olivine and carried back up to surface within komatiite lava flows.

This fossilized tree leaf, is the first of their kind to have been found in the area. Alexandre Demers-Potvin, used the samples he collected to establish that Eastern Canada would have had a warm temperate and fully humid climate during the middle of Cretaceous period.

Colossal dinosaur bone find in France thrills scientists

Wells drilled into Oklahoma's Arbuckle formation inject wastewater (1) which then disperses through the rock. As it spreads, the wastewater can trigger earthquakes in fault zones (2), but their size depends on the amount injected and the rock's properties. The new model can predict quake probabilities by the quantity of wastewater injected.

Predicting earthquake hazards from wastewater injection

Multiple volcanic craters cover the 'Campi Flegrei' near Naples, Italy. A new method aims at forecasting where new vents will occur.

How to recognise where a volcano will erupt

Earthquakes run in packs, but you can hear them coming, as noted in research from Los Alamos National Laboratory and California Institute of Technology.

These fossil-rich sediments along the Alto Madre de Dios River in southern Peru have yielded hundreds of fossil teeth and bones, clues to what life in the Amazon was like 18 million years ago.
