A team of researchers with the University of Ottawa has used teleseismic data from on- and off-shore sensors to learn more about the low-viscosity layer (LVL) present in a northern part of the Cascadia subduction zone. In ...
The Cascadia Subduction Zone off the coast of the Pacific Northwest has all the ingredients for making powerful earthquakes—and according to the geological record, the region is due for its next "big one."
