Slow-slip earthquake in progress near Hawke’s Bay, New Zealand
A slow-slip earthquake (SSE) event has been occurring near New Zealand’s Hawke’s Bay, along the Hikurangi Subduction Zone since early December.
Slow slip events underway on Hikurangi subduction zone in New Zealand, releasing energy equivalent to M7 earthquake
Another slow-motion earthquake, or “slow slip event,” is now underway on the Hikurangi subduction plate boundary offshore the North Island’s east coast. The amount of slow slip movement during the last month has released energy equivalent to a magnitude 7 earthquake.
Two slow-motion earthquakes under North Island, New Zealand
Two slow-motion earthquakes have been taking place so far in 2022 under the central and eastern North Island, New Zealand. These events are like earthquakes in slow motion, unfolding over weeks to months and cannot be felt by humans.
Slow-slip event in progress under the Kāpiti-Horowhenua area, New Zealand
A slow-slip event began under the Kāpiti-Horowhenua area, New Zealand in mid-September 2021, and is expected to continue for several more months. The part of the subducting Pacific Plate 30 – 50 km (18 – 31 miles) beneath Kāpiti has started moving slowly again…
New slow-slip event detected near Gisborne, New Zealand
A slow-slip event started around June 14, 2021, near Gisborne, New Zealand and models suggest several cm of movement has occurred at the plate boundary so far. This is the second slow-slip event off the coast of North Island since the May 2021 event near Porangahau….
Slow-slip earthquake occurring off the east coast of North Island, New Zealand
A large, slow-slip earthquake is occurring off the east coast of North Island, New Zealand. The event began off the coast of Porangahau last week in the same area as the one that occurred shortly after the massive M7.8 Kaikoura Earthquake of November 2016. Based on…
Slow-slip event off the coast of Gisborne: plate movement equivalent to a magnitude 7.0 earthquake, New Zealand
GNS scientists are monitoring a slow-slip event near Gisborne, off the east coast of North Island, New Zealand. This is an update on this event since it started registering in late March 2019. Slow-slip events are also known as "silent" earthquake. These…
Slow-slip event detected off the coast of Gisborne, New Zealand
GNS scientists are monitoring a slow-slip event that started at the end of March 2019 near Gisborne, off the east coast of North Island, New Zealand. Slow-slip events are linked to an increase in localized earthquake activity. A similar sequence of earthquakes was…
