Ancient Methane Seeps Tell Tale of Sudden Warming
Newly discovered rock mounds left by ancient methane seeps give scientists clues that methane on ancient ocean floor was released by ancient global warming.
Neotectonics and Earthquake Forecasting
The editors of a new book describe the evolution of major earthquake producing fault zones in the eastern Mediterranean region and explore how earthquake forecasting could improve.
Alteration Along the Alpine Fault Helps Build Seismic Strain
Detailed analysis of cores drilled through New Zealand's most dangerous on-land fault indicates that its permeability and strength are altered by mineral precipitation between seismic events.
Merle Lee Allison (1948–2016)
A dynamic geologist with a knack for organizing people, he served as state geologist in three different states and pioneered global efforts to develop cyberinfrastructure for the Earth sciences.
New Ground-Penetrating Radar Method Shows Promise in Aquifer
Recent advances in ground-penetrating radar data analysis could help reveal aquifer structure in unprecedented detail.
