Yellowstone spawned twin super-eruptions that altered global climate

(Geological Society of America) A new geological record of the Yellowstone supervolcano's last catastrophic eruption is rewriting the story of what happened 630,000 years ago and how it affected Earth's climate. This eruption formed the vast Yellowstone caldera observed today, the second largest on Earth.

Why did the 2014 Oso landslide travel so far?

(Geological Society of America) On Saturday, 22 March 2014, a devastating landslide roared across the North Fork of the Stillaguamish River, near Oso, Washington. The landslide killed 43 people as it plowed through the Steelhead Haven neighborhood. When it stopped, after crossing the river, the neighborhood, and State Route 530, the Oso landslide had traveled 1.4 kilometers.

Moment of impact: A journey into the Chicxulub Crater

Slab failure magmatism: the missing link to the formation of continents

(Geological Society of America) Earth has two types of crust: oceanic crust is relatively young, dense, and made at mid-oceanic spreading centers, whereas continental crust is buoyant, old, and believed to be created in magmatic arcs. Show More Summary

Food for thought: Current topics at the intersection of geoscience & society

Tectonic linkages and feedback mechanisms in orogenic systems

(Geological Society of America) Plates collide and mountain ranges form, and the why and how are key to understanding orogenic processes. This volume explores linkages between tectonic processes through a series of field, numerical modeling,...Show More Summary

12,000 years ago, Florida hurricanes heated up despite chilly seas

(Geological Society of America) Category 5 hurricanes may have slammed Florida repeatedly during the chilly Younger Dryas, 12,000 years ago. The cause? Hurricane-suppressing effects of cooler sea surface were out-weighed by side effects of slowed ocean circulation. Show More Summary

2011 Tohoku-oki earthquake: Results from seismic reflection data

(Geological Society of America) A striking finding of the 2011 Tohoku-oki earthquake (Mw 9.0) is that more than 50 meters of coseismic fault slip reached the trench axis. In addition to this, seismological studies found a clear depth-dependent variation in the source location between high- and low-frequency seismic energy radiation. Show More Summary

Pinpointing the sources of trans-pacific dust

(Geological Society of America) Airborne dust from Asia travels across the Pacific passport-free, carrying pollution, building soil, and coloring sunsets thousands of miles from its source. Identifying that source is important for understanding atmospheric circulation, contaminant pathways, and climate. Show More Summary
