Slow-motion earthquakes, as you might guess from the name, involve the release of pent-up geological energy over the course ...

The 1980 eruption cycle made Mount St. Helens one of the most famous volcanoes in the Cascades. But it is far from the only volcano in the range.

A megasplay fault branches upward from the subduction zone, and in the event of "The Big One," would raise the seafloor, displacing a massive amount of water closer to the coast.

A huge earthquake is brewing along the Cascadia Subduction Zone that could destroy bridges, reshape the landscape and trigger a massive tsunami.

As the most seismically active regions in the world, oceanic subduction zones show contrasting seismicity in different regions. A review by a team from Nanjing University explored the ...

When an earthquake rips along the Cascadia Subduction Zone fault, much of the U.S. West Coast could shake violently for five minutes, and tsunami waves as tall as 100 feet could barrel toward ...

Subduction zones are the most important sites of material exchange between the crust and mantle on Earth. They are also the locations where the largest deposits of strategic metals, such as copper, ...

Now, scientists aim to get their clearest picture yet of the complex mechanics of our big-risk Hikurangi Subduction Zone – and what sets it apartfrom similar systems around the planet.

Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than previously thought — and may be a big reason that our planet harbors life.

Here is another Earthquake Preparedness video. This one features "The A-Maze-ing Picture Hook", made by QuakeHold. The innovative "maze" design securely attaches wired picture frames and mirrors ...
