Latest Cascadia earthquake Stories
In an attempt to better prepare for future massive “megathrust” earthquakes along the west coast of Canada, researchers have prepared a record of earthquake history in southern British Columbia.
Scientists have long been baffled by a massive earthquake that struck the western coast of North America in 1700.
A comprehensive analysis of the Cascadia Subduction Zone off the Pacific Northwest coast confirms that the region has had numerous earthquakes over the past 10,000 years, and suggests that the southern Oregon coast may be most vulnerable based on recurrence frequency.
Scientists at UC Santa Barbara have accumulated the first evidence-based inclusive study of the probability for tsunamis in Northwestern California.
While Japanâ€™s massive earthquake and accompanying tsunami represent a devastating natural disaster for the countryâ€™s residents, scientists should also seize upon the massive temblor as an important learning tool for future quakes around the world, including the Pacific Northwest coast of the United States.
The major earthquakes that devastated Chile earlier this year and which triggered the catastrophic Indonesian tsunami of 2004 are more than just a distinct possibility to strike the Pacific Northwest coast of the United States, scientists say.
Some time soon, a powerful earthquake will trigger a massive tsunami that will flood the Pacific Northwest, destroying homes and threatening the lives of tens of thousands of people.
The potential for a huge tsunami on the West Coast of North America warrants immediate review of regional evacuation plans, geologists said. A future tsunami could be far larger than the one generated by the great 1964 Alaskan earthquake, which sent huge waves as far south as Northern California, University of Utah geologist Ron Bruhn said. Bruhn's team gauged the power of earthquakes, and resulting tsunamis, by studying 2,000 years of subsoil along the Alaskan coast.
The potential for a huge Pacific Ocean tsunami on the West Coast of America may be greater than previously thought, according to a new study of geological evidence along the Gulf of Alaska coast.
A new study evaluates expected ground motion in Seattle, Victoria and Vancouver from earthquakes of magnitude 7.5 - 9.0, providing engineers and policymakers with a new tool to build or retrofit structures to withstand seismic waves from large "subduction" earthquakes off the continent's west coast.
