Cryovolcanoes, landslides, and water ice all point to current activity, researchers found.

How Did Fragile Early Microbes Become Fossils?
During the Ediacaran period more than a half billion years ago, clay mineral coats likely shielded delicate remains, helping them become exquisitely preserved in rock, recent experiments suggest.
Cold Temperatures Set Off Slow-Moving Landslides
Falling ground temperatures in the cold season are found to trigger shallow, slow-moving landslides on slopes with clayey soil.
Tiny, Deep Quakes Increase on San Andreas as Tides Tug on Fault
When the gravity of the Sun and Moon causes Earth's crust to bulge every 2 weeks, slow-moving earthquakes proliferate in the lower reaches of the San Andreas, a new study finds.
Earth Fissures May No Longer Get Mapped in Arizona
A program that monitors giant cracks in the ground that suddenly appear after heavy rain could become a casualty of budget cuts to the Arizona Geological Survey.
Despite Dryness, Quartz Grains Can Deform in Earth's Crust
A comparison of water content in undeformed and deformed quartz indicates that grains may change shape via weakening processes that cannot be duplicated in laboratory experiments.
Gypsum Forms in an Unexpected Way
Scientists spot the "stem cell" building blocks that lay the foundation for gypsum's formation.
AGU Workshops for Authors and Reviewers
AGU and AGU editors led a number of workshops in 2015 on how to be a successful author to worldwide audiences as well as to how to effectively review scientific papers. First, Yusuke Yokoyama (Editor for Geochemistry, Geophysics, Geosystems) convened a workshop at the JPGU meeting in Tokyo, Japan.
Developing New Rock Magnetic Tools to Drive Geoscience Research
First Order Reversal Curve Workshop (FORCshop); Minneapolis, Minnesota, 23–24 July 2015
What Is the Anthropocene?
Geologists must consider whether the Anthropocene is a specific segment in the continuum of time or a holistic concept.
