The subduction of topographic features has been linked both to earthquake generation and the segmentation of faults. Seismic imaging reveals a seamount subducted to 40-km depth below Sumatra that ...

Understanding subduction zone earthquakes: The 2004 Sumatra earthquake Date: June 23, 2015 Source: Geological Society of America Summary: The 26 December 2004 Mw ~9.2 Indian Ocean earthquake (also ...

The results indicate that although a subduction-zone event in the Sunda trench has been made more likely by the Sumatra–Andaman earthquake, at present the increase in stress is localized on the ...

The Cascadia Subduction Zone looks a little different than researchers thought. Here's what that means for 'The Big One' Although the hazards may be different, that does not mean the risk is less ...

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 ...

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.

The Hikurangi subduction zone: a credible magnitude 8.9 earthquake and tsunami scenario. Video / East Coast LAB Mysterious, silent earthquakes could be key to forecasting the next catastrophic ...

NEW DELHI: A recent study from scientists in Portugal has raised concerns about the future of the Atlantic Ocean. They have identified a subduction zone, known as the 'Ring of Fire', that could ...

The Chilean subduction zone is geologically active enough to provide useful information and is a good locale for comparative studies with Cascadia and Alaska. The SZ4D implementation plan recommends ...

In 2011, the seafloor jolted and sent waves up to 133 feet (41 meters) high over parts of Japan. In 2004, the entire planet vibrated as an undersea quake near Sumatra pushed tsunamis over ...

Although it may seem like an eternal feature of Earth, the Atlantic Ocean could be swallowed by a vast subduction zone, dubbed the 'Ring of Fire', a new study warns. Scientists in Portugal say ...
