subduction

Some of the strongest earthquakes that people experience occur along subduction zones.

In New Zealand, where Wallace works, earthquakes do indeed occur during slow-slip events along this region’s subduction zones.

The Mariana Trench, the deepest point in the world, occurs in a subduction zone.

Kane, for instance, points out that a planet’s habitability is guided by a number of factors, including plate tectonics and subduction—a process that recycles carbon from the atmosphere into the planet’s interior—and its atmospheric chemistry.

They base this on tiny, 4-billion-year-old crystals whose chemistry resembles that of modern rocks produced in subduction zones.

Predicting the exact arrival of a Cascadia Subduction Zone quake is also nearly impossible, and constantly evolving.

The Cascadia Subduction Zone is the wonky name for the place where all this mayhem will begin.

Subduction zones are found where one plate overrides, or subducts, another, pushing it downward into the mantle where it melts.

There are three types of plate boundaries: spreading zones, transform faults, and subduction zones.

Most faulting along spreading zones is normal, along subduction zones is thrust, and along transform faults is strike-slip.

And from hence lastly doth arise the solidity of the section, by addition and subduction.

The lines with barbs show zones of underthrusting (subduction), where one plate is sliding beneath another.
