Last year’s earthquake is now believed to be one of the most complex ever recorded.
The Kaikōura Earthquake was better documented and measured than any natural event in our history. As the data streams in, scientists are scrambling to decode its hidden meanings.
The Alpine Fault ruptures—on average—every 330 years with a magnitude 8 earthquake. Geologists and authorities are racing to quantify what might happen, and how they might respond in the event of the next one, likely to occur some time in the next 50 years.
Still reeling from the Darfield quake, an massive aftershock damaged much of the CBD in Christchurch, forcing the city to re-evaluate its future.
Seismic engineering is failing to anticipate the complexity of earthquakes.
In 1931, New Zealand’s largest earthquake of the 20th century shook the centre of Napier to rubble. Fires then burned much of what remained. Out of the ashes, Napier’s citizens built what they hailed as “the newest city on the globe,” modelled on the latest architectural fashions.
The devastating earthquakes have forced a re-evaluation of Christchurch’s heritage buildings. What should be demolished, what should remain?
GNS scientists - and our reporter Tracy Neal - have been getting up close and personal with the Kekerengu Fault.
A 7.1-magnitude earthquake ruptured under Darfield causing widespread damage. Previously unknown to geologists, the new fault also shook the scientific establishment.
Entire suburbs were ‘red-zoned’ after the 2011 earthquake in Christchurch. Even now, the fate of these properties and the few residents still wrangling with authorities remains uncertain.
An investigation into the anatomy of an earthquake: from the science behind recent events, ramping to a mega earthquake that’s yet to happen – the Mega Disaster.
How does the movement of the earth's crust get recorded and then broadcast as an alert to your phone within seconds? To discover how the information moves from a fault line in the South Island to your digital device we headed out with some of the team from GeoNet.
New Zealand’s largest earthquake in European times struck the centre of the country almost 150 years ago. Although the later Murchison and Napier earthquakes claimed more lives, neither created the geological upheaval wrought by the Wairarapa earthquake of 1855.
A group of New Zealand seismic engineers has been working to make rigid structures, such as buildings and bridges, more flexible and resilient, by supplying them with “soft parts”.
Well, sort of. As ice sheets melt in the northern hemisphere, magma flows more readily, causing minor earthquakes, increased geothermal activity and possible even eruptions.
The magnitude 7.8 Kaikōura earthquake triggered a massive underwater landslide that swept down the offshore canyon system and was still flowing more than 300 km away.
