    Corvallis is located in Benton County and the Willamette Valley between the Coast Range and the Cascades. Corvallis is 85 miles south of Portland (/2 hour drive or a minute flight) and, 45 miles north of Eugene. Both Portland and Eugene have excellent air service. the present-day San Andreas transform fault system [Atwater, , ]. At present, much of the transform motion in the San Andreas fault system appears to be taken up in the Coast Range east of the San Andreas fault along the Maacama and Bartlett Springs faults .

Due to the size and location of these mega earthquakes, Oregon’s coast gets hit hard with tsunami water displacement movement.

The eruption of camptonite flows and intrusion of nepheline syenite in the central Oregon Coast Range at Ma were approximately contemporaneous with the eruption of the Cascade Head volcanics at Ma, and the flows appear to be lesser partial melts of the Cascade Head and Yachats sources (Oxford, ; Parker et al., ).

A Brief Summary of Oregon Coast Range Geology, Geomorphology, Tectonics, and Climate Geology 4/ Tectonic Geomorphology, University of Oregon Spanning miles along the Pacific, the Oregon Coast Range is defined by a mile wide swath of moderately high mountains. The range averages 1, feet in elevation and has a maximum elevation.

In the Oregon Coast Range (OCR), rhythmically bedded sandstones of the Eocene Tyee Formation underlie steep, soil‐mantled hillslopes, with relatively uniform ridge‐valley spacing. These characteristic landforms are perturbed where diagenetic variations manifest as resistant cliffs.

Geologic framework and evidence for neotectonism in the epicentral. 1 day ago  The earliest evidence for subduction, which could have been localized, does not signify when plate tectonics became a global phenomenon. To test the antiquity of global subduction, we investigated Paleoproterozoic time, for which seismic evidence is available from multiple continents.

We used a new high-density seismic array in North China to image the crustal structure that exhibits a dipping.
