Off the coast of Vancouver Island, a slab of ocean floor has dropped by about five kilometers along a fault that scientists ...

The present solid Earth is actually active, with new plates generating in the mid-ocean ridges and some old plates sinking back into the interior through subduction zones. Subduction is thus a key ...

Water may have been shaping Earth’s deep interior far earlier than many geologists thought. In rocks more than 3 billion years old from Western Australia, a research team found chemical signs that ...

Add Yahoo as a preferred source to see more of our stories on Google. PORTLAND, Ore. (KOIN) – A new study mapping the Cascadia Subduction Zone is giving scientists clues about the state of the fault ...

One longstanding enigma in geology is how one tectonic plate can break Earth's rock-hard shell and begin diving under another in the process known as subduction. "We now know how subduction nucleated ...

Jessica DePaolis (second from left) and the team of researchers studied and compared sedimentary core samples in Montague Island, Alaska, and found evidence that four of the past eight earthquakes ...

(a) Geological units and earthquake distribution of an oceanic subduction zone. The orange shadow beneath the volcanic arc represents partially molten areas and magma channels. (b) Thermal structure ...

Beneath our feet, the Earth is in a constant, slow negotiation with itself. Tectonic plates grind, lock, flex, and ...

The SZ4D Implementation Plan details how the scientific community plans to make major advances in understanding subduction zone hazards. Subduction zones, where one tectonic plate slides beneath ...

Researchers have conducted detailed structural analyses of a fault zone in central Japan to identify the specific conditions that lead to devastating earthquake. The seismic slip processes that were ...
