A large earthquake is happening right now - but you can't feel it

Scientists are closely watching a silent, slow-burning earthquake off the east coast of the North Island - and sophisticated sensors only recently placed around the site are expected to reveal a wealth of exciting new insights.

Sinking seamounts make and muffle earthquakes

Subduction zones- places where one tectonic plate dives beneath another- are where the world’s largest and most damaging earthquakes occur. A new study has found that when underwater mountains, also known as seamounts, are pulled into subduction zones, not only do they set the stage for these powerful quakes, they also create conditions that end up dampening them. The National Science Foundation-funded findings mean that scientists should more carefully monitor areas around a subducting ...

Why mysterious 'slow-motion' quakes hold big secrets

Unusual slow-burning quakes that silently unfold deep beneath New Zealand could allow scientists to better understand the violent, quick-fire shakes that Kiwis know much better. Tracking what are called slow-slip earthquakes – known to shift faults over days or months without any perceptible shifts in the earth - has only been made possible with recent advances in GPS technology. These events play out when faults grind incredibly slowly against each other, like an earthquake in slow motion.

Hikurangi on the move - OUTREACH FROM JOIDES RESOLUTION The Hikurangi Plateau is on the move - once part of a super-plateau it is unusually thick, large, and is subducting relatively quickly.

Seamounts – are they an important piece of the slow slip puzzle?

Seamounts – are they an important piece of the slow slip puzzle? - JOIDES RESOLUTION OUTREACH RESOURCE. What is a seamount? Seamounts are typically formed from extinct volcanoes that rise abruptly and are commonly found in marine environments and subduction zones. They often support healthy fisheries because they provide a rich marine ecosystem attracting plankton, corals, fish, and marine mammals alike. They are found all around the world in the ocean and follow a distinctive evolutionary pat
