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.

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.

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.
