Why it’s so important to mark the anniversaries of earthquakes – Ursula Cochran

Sarah-Jane O'Connor posted in on November 9th, 2017.

As the one year anniversary of the Kaikōura earthquake nears, GNS scientist Dr Ursula Cochran writes on The Spinoff why it’s important to mark the anniversaries of earthquakes, even ones that happened 300 years ago. An excerpt (read in full): Measuring how far we’ve come as a nation in living wisely with earthquakes is a […]

Kaikōura quake triggered slow-slip event – In the News

Sarah-Jane O'Connor posted in on September 12th, 2017.

Last November’s magnitude 7.8 Kaikōura earthquake triggered a series of major slow-slip events (silent earthquakes) beneath the east coast of the North Island, new research from GNS Science confirms. Published today in Nature Geoscience, the study used GeoNet’s network of GPS instruments to follow the slow-slip series, which in some areas are still continuing to […]

Auckland’s volcanic past: temperamental and unpredictable – In the News

Sarah-Jane O'Connor posted in on July 19th, 2017.

Auckland’s volcanic past has been punctuated by periods of heightened activity and thousands of years of silence, according to two new research papers. Researchers from the DEVORA (Determining Volcanic Risk in Auckland) research programme used argon-argon age dating to gather more precise timings of eruptions in the Auckland Volcanic Field. The oldest eruption (Pupuke) dates […]

Kaikōura shook more violently than Christchurch – In the News

Sarah-Jane O'Connor posted in on April 10th, 2017.

New insights from November’s magnitude 7.8 Kaikōura earthquake have revealed the shake was the most violent ever recorded in New Zealand. Research from GNS Science, published in Seismological Research Letters, showed that most of the ground motions recorded in the upper South Island were strong, but comparable to previous earthquakes. However, the small North Canterbury […]

Rethink of hazards after Kaikoura earthquake – Expert reaction

Sarah-Jane O'Connor posted in on March 24th, 2017.

Last November’s Kaikoura earthquake will likely change the way scientists think about earthquake hazards in plate boundary zones, according to the first study to come out of the data collected during and immediately after the earthquake. The study, led by GNS Science researchers, will be published on Friday in Science. A range of data – […]

GeoNet takes to Facebook Live for Kaikoura update – In the News

Sarah-Jane O'Connor posted in on March 16th, 2017.

Tuesday marked four months since the November 14 Kaikoura earthquake, which caused widespread damage and disruption along the east coast of the South Island and up into Wellington. To mark the date, GeoNet took to Facebook Live to discuss what its scientists had learnt about the 7.8 magnitude earthquake. After battling with some audio issues […]

Alpine Fault interval refined – In the News

Sarah-Jane O'Connor posted in on March 6th, 2017.

Improving on their 2012 study in Science, GNS Science researchers have refined their understanding of past earthquakes on the South-Westland section of the Alpine Fault. The additional data, published last week in Earth and Planetary Science Letters, brings the estimated average interval between quakes from 329 ± 26 years, down to 291 ± 23 years. Though the […]

Kaikoura earthquake – Expert Q&A with GeoNet

Sarah-Jane O'Connor posted in on November 21st, 2016.

Scientists are still unravelling what happened a week ago on several faults near Kaikoura and Culverden. We asked GeoNet scientists about what they have been finding out. What do we know about the possibility of stress added to neighbouring faults? “We understand this is an important question. We are currently developing the model for this […]
