Our Changing World

Audio, Radio New Zealand

Scientists are just beginning to understand why the recent Canterbury earthquakes 'punched above their size', and their findings could change international scientific thinking about earthquakes. Alison Ballance talks with GNS seismologists Martin Reyners and Bill Fry to find out more.

Audio, Radio New Zealand

Topics - The Gettysburg address, the short speech given by Abraham Lincoln 150 years ago today, the finest short speech in the English language, and one of the great political utterances of all time. A strong earthquake that hit Christchurch last night has been upgraded by GNS Science to a magnitude 4.6. It was also shallower than first believed, with GNS reporting it was 8km deep rather than 11km. Wallabies rugby coach Ewen McKenzie has made no apologies for suspending six of his players in what's been described as "a hard-line move designed to set the standards required to win the 2015 World Cup".

Chances of magnitude aftershock hitting rapidly decreasing

The Panel with Rosemary McLeod and Tim Watkin (Part 1)

Audio, Radio New Zealand

Topics - Would you like a pay rise of $10,000 a year? That's what the lowest paid Auckland Council staff will get if a plan to implement a minimum wage of $18.40 an hour goes through. The Insurance Council has received a briefing today after a report revealed hundreds of properties on Christchurch's Port Hills are on unsafe land. The GNS Science report released yesterday shows a major rain or snow storm could cause land already loosened by the earthquakes to move.

Forecasting future earthquakes in New Zealand

Audio, Radio New Zealand

Mention the words "earthquake" in the same brief as "remediation" and it's enough to strike fear in the hearts of all New Zealanders, particularly those in Christchurch and other earthquake prone areas of the country. Now we find the chances of the ground shaking more violently in a quake is much higher than previously thought for large parts of the country. In some places it has doubled or even trebled. What are the ramifications of this new found knowledge? Joining the show to discuss is Michelle Grant, President of the Structural Engineering Society New Zealand, and Matt Gerstenberger, Principal Scientist and Seismologist at GNS Science
