A Bosnian pine (Pinus heldreichii) growing in the highlands of northern Greece has been dendrocronologically...
Michael Floyd, a research scientist in MIT’s Department of Earth, Atmospheric and Planetary Sciences, says that in developing seismic hazard assessments, it’s important to consider afterslip and slowly creeping faults, which occur often and over long periods of time...

A researcher at Ben-Gurion University of the Negev (BGU) has identified that the eastern Mediterranean Sea contains the world's oldest oceanic crust still in place and could be almost 340 million years-old.
The study reported this week in Nature...
Researchers at The Ohio State University and NASA's Jet Propulsion Laboratory have created the first-ever map of key regions of "submarine groundwater discharge," where freshwater and seawater mix unseen below ground. The previously hidden sites mark areas of vulnerability...
