The Seattle fault, tsunami deposits, and catastrophic flooding

(Geological Society of America) A new volume prepared in conjunction with GSA's 2017 Annual Meeting offers ten guides that geographically focus on the Seattle, Washington, area within the Puget Lowland, and also includes descriptions of trips in the Cascade Range, the region east of the Cascades, and the Columbia River Basin and western Idaho.

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

(Geological Society of America) GSA is preparing to Livestream four thought-provoking lectures by leaders in their fields from its Annual Meeting & Exhibition in Seattle, 22-25 October 2017.

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

Discover Washington State geology with the experts

Follow the fossils, find the answers

(Geological Society of America) The fossil history of animal life in India is central to our understanding of the tectonic evolution of Gondwana, dispersal of India, its northward journey, and its collision with Asia. This beautifully...Show More Summary

More evidence of water on Mars

(Geological Society of America) River deposits exist across the surface of Mars and record a surface environment from over 3.5 billion years ago that was able to support liquid water at the surface. A region of Mars named Aeolis Dorsa contains some of the most spectacular and densely packed river deposits seen on Mars.

GSA Annual Meeting demonstrates commitment to RISE

(Geological Society of America) GSA is taking action on its long-standing commitment to diversity and inclusion in the geoscience community. From its recently penned Events Code of Conduct (,...Show More Summary

GSA technical program is live

(Geological Society of America) A record 4,950 abstracts have been submitted for the Geological Society of America's Annual Meeting & Exposition to be held in Seattle, Wash., Oct. 22-25, 2017 and over 7,500 geoscientists are expected to attend. 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

Geological Society of America announces fellows for science policy and communication

(Geological Society of America) The Geological Society of America has announced three 2017-2018 Fellows who will assist with efforts to increase efficacy in serving society through science.

Post-glacial history of lake of the woods

(Geological Society of America) The extent and depth of lakes in glaciated regions of North America are controlled by climate and the influence of differential isostatic rebound of the land's surface that began when Pleistocene ice melted from the continent. Show More Summary

Cave mazes

(Geological Society of America) Analysis of caves in Israel deserts brings to light the ancient groundwater circulation of northwestern Arabia. The cave distribution, morphology, and deposit evidence indicates that they formed through dissolution by rising groundwater. Show More Summary

Geological Society of America honors Excellence in Geoscience for 2017

(Geological Society of America) The Geological Society of America (GSA) recognizes outstanding scientific achievement and distinguished service to the profession each year at its Annual Meeting & Exposition, held this year in Seattle, Washington, USA.

Geology rocks the Pacific Northwest: GSA Meeting returns to Seattle

(Geological Society of America) Registration is open for The Geological Society of America's Annual Meeting & Exposition, to be held Oct. 22-25 2017 at the Washington State Convention Center in Seattle, Washington, USA.

Charred flowers and the fossil record

(Geological Society of America) One of the main types of fossil used to understand the first flowering plants (angiosperms) are charred flowers. These charcoals were produced in ancient wildfires, and they provide some evidence for the types of plants that grew millions of years ago. However, when fires burn they not only produce charcoal, but they also destroy it.

Dinosaur Provincial Park, the Canadian Rockies, and the fossils of the Burgess Shale

(Geological Society of America) A field guide in conjunction with GSA's Rocky Mountain Section meeting offers five field trips that explore the structural geology, sedimentology, and paleontology near Calgary, as well as examining the relationship of the geology to the regional petroleum and mining industries. Show More Summary
