A study of an emerging zone off New Zealand suggests that the process, vital for life on Earth, may at first be localized and then develop into something much larger.

Researchers have set sail to find and map a fault that causes giant earthquakes in the Pacific Northwest.
Tightly packed sediments help the Cascadia Subduction Zone generate large earthquakes, and could boost its ability to trigger a large tsunami.
Off the coast of New Zealand, there is an area where earthquakes can happen in slow-motion as two tectonic plates grind past one another. These slow-slip events create an ideal lab for studying fault behavior along the shallow portion of subduction zones.
Ancient faults that formed in the ocean floor millions of years ago are feeding earthquakes today along stretches of the Alaska Peninsula, and likely elsewhere, a new study suggests.
