Murchison and geology - Out of Space

Duncan Steel Jun 19, 2019

There are many places, both in New Zealand and elsewhere around the globe, that are named for the nineteenth-century Scottish geologist Sir Roderick Impey Murchison. It seems astonishing how many of these are connected in some way with events of geological significance, or are otherwise of scientific importance.  One of my predilections is writing blog posts prompted by the occurrence … Read More

After the quakes – hard lessons that help us all do better - Scibooks

Peter Griffin Dec 08, 2017

I was at the science communicator’s conference in Auckland on the afternoon of 22 February, 2011, when the massive earthquake struck Christchurch. The theme of the conference was “Listening to the other side” and we’d enjoyed several stimulating discussions during the day as non-scientists gave their views on ways to effectively communicate the science of complex issues. That abstract … Read More

Guest Author Mar 27, 2017

By Stephen Hicks, University of Southampton No one could have expected what was to hit New Zealand in 2016. The country is certainly no stranger to being shaken up by moving tectonic plates.

Quake-prone heritage buildings: spring cleaning - The Dismal Science

Eric Crampton Nov 25, 2016

Wellington’s quake-prone heritage-listed buildings remain scary. My column in this week’s NBR ($) suggests prioritising the risky heritage buildings, pulling the heritage listings from the scariest ones, and putting public money into the ones where the heritage amenity is really worth it.  Or, Council could just buy the buildings from their owners, fix them itself, and sell them afterwards – … Read More

Red Zone: Property rights are human rights - The Dismal Science

Eric Crampton Nov 07, 2016

New Zealand’s Human Rights Commission says that property rights need to be protected in the Bill of Rights. I couldn’t agree more enthusiastically. The report is about what the government did to people in Christchurch’s Red Zone. The land around the Avon River was a mess after the quakes. The government decided that the simplest thing … Read More

Disaster recovery is local - The Dismal Science

Eric Crampton Nov 04, 2016

There are a lot of lessons from Hurricane Matthew that New Zealand might have found useful in the aftermath of the Canterbury earthquakes.  Vero de Rugy has a great summary of Virgil Storr’s work for the Mercatus Centre on hurricane recovery in New Orleans. Take a recent investigation by PBS’ “Frontline” and NPR into flood insurance and aid … Read More
