Bryan L. Isacks Receives 2014 Walter H. Bucher Medal
Bryan L. Isacks was awarded the 2014 Walter H. Bucher Medal at the AGU Fall Meeting Honors Ceremony, held on 17 December 2014 in San Francisco, Calif. The medal is for “original contributions to the basic knowledge of the crust and lithosphere.”
Using Rivers to Investigate Rock Uplift in Taiwan
Researchers use change of slope in a dense river network to investigate rock uplift rates of Taiwan.
River Slope Connects Modern Topography with Ancient Tectonics
Scientists create models to help them figure out how the slope of a river can record ancient tectonic activity.
Measuring Small-scale Changes Along a Fault as Plates Slip
A see-through plastic fault lets researchers directly measure how earthquake stresses affect fault properties.
Changing Crustal Velocities Preceded 2011 Tohoku-oki Quake
Researchers examined the crustal deformation associated with earthquakes that occurred before the 2011 Tohoku-oki earthquake.
Tectonic Events May Have Triggered the Cambrian Explosion
A researcher proposes a tectonic mechanism that could have helped drive one of the biggest evolutionary events in history: the Cambrian Explosion.
A Window into the Pyrenees Mountains' Geologic Past
Researchers use ancient rifting systems in the Bay of Biscay to investigate the precollision history of the Pyrenees Mountains.
Toward Another Lava Lake in the Virunga Volcanic Field?
Earlier this year, a red glow became visible atop Nyamulagira, a volcano in the East African Rift. Helicopter flights soon confirmed lava fountains inside a pit crater on the volcano's central caldera.
Thin Precollision Crust Can Explain Aspects of Indo-Asian Convergence
The paradoxical thickness of the Tibetan Plateau has puzzled scientists for decades. Now new research offers up an explanation for this mystery.
