Scientists say it's not beyond the realms of possibility that New Zealand could have a sophisticated earthquake early warning (EEW) system - alerting people seconds before a big disaster hits.

Tash Joyce had a very special delivery waiting in her post box.

A renowned Auckland brain scientist has been recognised with New Zealand's highest honour for research - the Rutherford Medal.

These graphics show how Marlborough's faults were set off one by one in the 7.8 Kaikoura Earthquake.

By noon today, scientists had recorded nearly 5000 aftershocks from last Monday's big shake. But what are aftershocks and what can they tell us? Jamie Morton explains.

A pumice raft spotted by a Royal New Zealand Air Force crew has pointed to a possible major undersea eruption somewhere in the Tonga-Kermadec volcanic arc.

Parts of New Zealand are sinking at faster rates than others and will be subjected to higher levels of future sea level rise, a scientist says.

Scientists have revealed astonishing new insights into how the 7.8-magnitude quake affected New Zealand's seabed.

How has Kaikoura's world-famous wildlife responded to the 7.8 earthquake? Science reporter Jamie Morton looked at what we know so far.

The probability of another 7.0-plus quake striking have fallen further, GeoNet reported today, but large aftershocks are still likely across a large area of New Zealand.

Some children suffer from completely tangled hair, which, as their parents will attest, can't be combed at all. Scientists now have the answer.

Even after the quakes, eruptions and tsunami scares of the past decade, NZ still has lessons to learn about preparedness, writes Jamie Morton.

What happens to buildings when large earthquakes hit? What makes some structures more resilient than others? An expert explains.

Scientists have revealed the extent of uplift on the South Island's northeastern coast - observing that in some places the land was raised by two metres.

Earthquake experts have looked at scenarios for both the capital and Auckland. They've crunched the numbers, finding potentially catastrophic scenarios.

The probability of another plus-7 magnitude quake within the next month has fallen - but the chances of multiple large aftershocks remains a virtual certainty.

Why have there been so many landslides after this earthquake? Could we have known this would happen? Experts shed some light on Kaikoura's devastation.

Science reporter Jamie Morton talks to GNS Science earthquake geologist Dr Rob Langridge, who has been on the ground mapping damage around Marlborough.

Civil Defence is warning that a 150m high dam is at risk of failure after heavy rain.

Geotechnical engineers face an "unprecedented" challenge in tackling the many large landslides that have blocked quake-damaged Kaikoura's coastal State Highway 1.

The elevation of Monday's quake from a magnitude 7.5 to 7.8 makes it compare in size only with four other New Zealand quakes in the past 150 years.

What's it like to be part of the team at GNS Science when a big quake hits? Seismologist Dr Helen Anderson shares an insight.

The latest earthquake again prompted reports of animals behaving strangely just before the main shock hit. What does science say?

It appears our volcanoes have slept through the Kaikoura quake, with monitoring equipment showing only a few tremors over recent days.

The probability of another huge quake over magnitude 7 in the next 24 hours has been put at 4 per cent - but at 14 per cent in the next week and 22 per cent across the next 30 days.

Could Monday's quake trigger a sleeper tsunami or an Alpine Fault quake? Are we living in an era of quakes? Science reporter Jamie Morton tackles the big questions.

The energy unleashed in the Kaikoura earthquake was equivalent to what could power Christchurch for an entire year.

The now-named Kaikoura Earthquake triggered 100,000 landslides in Northern Canterbury and southern Marlborough.

Scientists are trawling through data to see how New Zealand has shifted following the latest quake.

International scientists are intrigued at the complexity of the suspected twin quakes that rattled New Zealand overnight.
