Scientists discovered a crack under the sea off Vancouver Island, NFZ in Cascadia region, that could alter Pacific subduction ...

Even long-lived subduction zones eventually die, and scientists believe they are witnessing the slow death of one in the northern end of the Cascadia subduction zone.

For decades, the end-stage life of a subduction zone existed only in theory. Now, for the first time in geologic history, scientists are bearing witness to the Juan de Fuca Plate tearing apart and ...

One of the most dangerous faults in the United States, the Cascadia Subduction Zone, may be able to trigger an earthquake on the San Andreas Fault, a new study says. But some scientists want more ...

The discovery, made just off the coast of Vancouver Island in the Pacific Ocean, shows that a section of the oceanic crust is slowly breaking apart beneath the North American Plate. Using seismic data ...

Two fault lines on the west coast of North America — the Cascadia and San Andreas — appear to be seismically synchronized, with past earthquakes on one fracture zone appearing to trigger a seismic ...

For the first time, scientists have directly observed a subduction zone beginning to break apart. Subduction zone is the place where one tectonic plate moves under another. This discovery, published ...

The earthquakes off the Oregon coast serve as a reminder of the seismic volatility in the Pacific Northwest. The USGS is actively gathering data on the intensity of these quakes through the Community ...

There are many Aberdeens — at least 14 around the world. But there’s only one Hoquiam. That said, how Hoquiam got its unique ...
