A new look 100 miles beneath a massive tectonic plate as it dives under North America has helped clarify the subduction process that generates earthquakes, volcanoes and the rise of the Cascade Range in the Pacific Northwest.
A new analysis suggests that massive earthquakes on northern sections of the Cascadia Subduction Zone, affecting areas of the Pacific Northwest that are more heavily populated, are somewhat more frequent than has been believed ...
The gravitational tug between the sun and moon is not just a dance of high and low tides: It can also trigger a special kind of earthquake on the San Andreas Fault.
It was here before anyone made a map and called this corner of it the Pacific Northwest.
When Jerry Paros shipped a seafloor sensor from his plant in Redmond to Japan in 2010, he never expected to see it again.
Geologists from Brown University may have finally explained what triggers certain earthquakes that occur deep beneath the Earth's surface in subduction zones, regions where one tectonic plate slides beneath another.
As military helicopters ferry search and rescue teams over the Pacific Northwest, below them are scenes of devastation from a giant earthquake that could strike the region at any time.
Research teams have evaluated the major 7.8 magnitude subduction zone earthquake in Gorkha, Nepal, in April 2015, and identified characteristics that may be of special relevance to the future of the Pacific Northwest.
The Cascadia subduction zone (CSZ) has captured major attention from paleoseismologists due to evidence from several large (magnitude 8-9) earthquakes preserved in coastal salt marshes. Stratigraphic records are proving to ...
Bracing for a tsunami like the one that devastated Japanese communities during a 2011 mega-earthquake, coastal communities from British Columbia to California have been grappling with how to protect people from a similar ...
