The 1,600 kilometres (990 mi) [4] long Macquarie fault zone (also known as the Macquarie Ridge, its gazetted name since 2015, [7] the Macquarie Ridge complex or historically as the Macquarie Fault) [Notes 1] is a major right lateral-moving transform fault along the seafloor of the south Pacific Ocean which runs from New Zealand southwestward towards the Macquarie triple junction.
The Cascadia subduction zone is a 960 km (600 mi) fault at a convergent plate boundary, about 100–200 km (70–100 mi) off the Pacific coast, that stretches from northern Vancouver Island in Canada to Northern California in the United States
A fault off the Pacific coast could devastate Washington, Oregon and Northern California with a major earthquake and tsunami. Researchers mapped it comprehensively for the first time.

Centered under the Pacific Ocean about 70 miles southwest of Eureka, the strong quake frayed nerves across most of California's North Coast. ... "looked like a war zone" after the shaking stopped ...
The Vanuatu subduction zone (previously called New Hebrides subduction zone) is currently one of the most active subduction zones on Earth, producing great earthquakes (magnitude 8.0 or greater), with potential for tsunami hazard to all coastlines of the Pacific Ocean. [2] [3] There are active volcanoes associated with arc volcanism.
A hole in a 600-mile-long fault line has been discovered at the bottom of the Pacific ocean - and it could be the trigger of a magnitude-9 earthquake on the US coast. Just outside of Oregon ...
