Figure 1. A map of the Cascadia subduction zone indicating the depth contours of the plate interface (gray lines) and Holocene volcanoes (black dots). All continuous GPS stations (diamonds and triangles) active within the time period from 1998-2008 and used in our analysis are shown. Those ...
aGlobal map showing the age distribution of the oceanic lithosphere with data from ref.12. Our study area (star), the Cascadia subduction zone, has a young and warm slab, in contrast to the old and cold slab in the other two subduction zones (squares; Japan and New Zealand) where eviden...

All along the Cascadia Subduction Zone are volcanoes. Most of them are inactive, but some are quite active. Here is a map of the volcanoes in the Cascade Mountains Range, so you have an understanding of the pressure relief valves (volcanoes) created over millions of years by these two tecto...
We report on slow earthquakes in Northern Cascadia, and show that continuous seismic energy in the subduction zone follows specific patterns leading to failure. We rely on machine learning models to map characteristic energy signals from... C Hulbert,B Rouet-Leduc,PA Johnson 被引量: 0发表: 2019...
Scenario:On June 9, 2022, A 9.0 magnitude Cascadia Subduction Zone (CSZ) earthquake ripping across the 700-mile CSZ fault line with no epicenter. An event of this type occurs on average once every 200 to 500 years. The last major CSZ earthquake and tsunami occurred on January 26, 1700...
We estimate present-day uplift rates along the Cascadia Subduction Zone in California, Oregon, and Washington in the Pacific Northwest, United States, by utilizing repeated leveling surveys and tide gauge records. These two independent data sets give similar profiles for latitudinal variation of contemp...
, 2006]. In the northern Cascadia subduction zone the deep tremor occurs with surprising regularity every 14 ± 2 months, in concomitance with episodic slow slip observed along the subduction strike (Episodic Tremor and Slip, ETS) [Rogers and Dragert, 2003; Royle et al., 2006]. During ...
Subduction zone fault processes range from tsunami-generating megathrust events to aseismic creep along the deeper portions of the fault. Episodic tremor and slow slip (ETS) represents the transition between these two regimes, where slip occurs at semi-regular recurrence intervals of months-to-years....
The Oregon Department of Geology is expecting tens of thousands of landslides to occur during a full rupture of the Cascadia Subduction Zone. The most at-risk areas have been mapped for the entire state of Oregon on a macro level in an online interactive map called “SLIDO“; they include ...
