Structure of the Cascadia subduction zone. The Cascadia subduction zone is a 1,000 km (620 mi) long dipping fault that stretches from Northern Vancouver Island to Cape Mendocino in northern California. It separates the Juan de Fuca and North America plates. New Juan de Fuca plate is created offshore along the Juan de Fuca Ridge.
Cascadia Cave is nearby. The cave is an 8,000-year-old American Indian petroglyph site considered to have the largest concentration of rock engravings in western Oregon. [3] Willamette Valley settlers developed a bypass at the park site for horse-drawn wagons. Old wagon ruts are still visible near where Soda Creek meets the South Santiam River. [2]
The name "Cascadia" was first applied to the whole geologic region by Bates McKee in his 1972 geology textbook Cascadia; the geologic evolution of the Pacific Northwest. Later the name was adopted by David McCloskey, a Seattle University sociology professor, to describe it as a bioregion. McCloskey describes Cascadia as "a land of falling waters."
Jun. 21—Making maps, hiking, exploring the geology around them and making a seismometer are among the things kids in University of Texas Permian Basin's Geology Camp have learned about this week.
On the academic side, there are engineering camps, biology camps, Makerspace camps, geology camp and more. The biology camp is for kids 12 to 18 and will be from 9 a.m. to 3 p.m. June 24-27.
Recent episodes of tremor and slip in the Cascadia region have occurred down-dip of the region ruptured in the 1700 Cascadia earthquake. Since the initial discovery of this seismic mode in the Cascadia region, slow slip and tremor have been detected in other subduction zones around the world, including Japan and Mexico. [5]
In western Oregon's ocean, the new Cascadia subduction zone laid the foundations for Oregon's modern Coast Range and improved ocean productivity, prompting diversification among the state's fauna. [4] At least 25 species of mollusk, including several snails, are known from the Fern Ridge Dam area alone. [21]
[1] [2] The stated mission of the center [3] is to (i) carry out basic and applied science research on earthquake hazards at the Cascadia Subduction Zone, (ii) promote access to careers in the geosciences, especially amongst minoritized individuals, and (iii) form partnerships between researchers and organizations in charge of response and ...
