U.S. Geological Survey scientist Jeanne Hardebeck calculated the frictional
strength of subduction zone faults worldwide, and the stresses they are under.

«Measuring the
strength of olivine is critical to understanding how strong tectonic plates are, which, in turn, matters to how plates break and create
subduction zones like those along the Cascadia plate, which runs down the west coast
of Canada to the west coast
of the United States,» said Warren, a geologist in the College
of Earth, Ocean, and Environment.
Its
strength resulted from the abrupt release
of plate tectonic forces, a process known as
subduction, centered on an area beneath Honshu where it slides over the top
of oceanic crust.
That is partly because
subduction - zone earthquakes occur offshore, and the
strength of the shaking diminishes quickly with distance.
