The earthquake apocalypse – it’s coming. Probably.

Something slightly scary occurred to me the other day. Analysis of the Mw 7.8 quake that ripped through central New Zealand last November suggests it was awesomely complex. We usually imagine quakes being caused when one fault line moves. Or maybe two or three faults, because faults tend to exist in connected systems. And often, … More The earthquake apocalypse – it’s coming. Probably.

New Zealand is earth’s eighth continent. Just mostly underwater.

I was all ‘woohoo’ last week when news broke that New Zealand is actually a continent about half the size of Australia, albeit mostly underwater. The discovery was published in the March-April issue of GSA Today in a paper authored by a team of New Zealand and New Caledonian geologists, including Nick Mortimer, Hamish Campbell, … More New Zealand is earth’s eighth continent. Just mostly underwater.

Does the Moon cause earthquakes – or is that a bit looney?

The magnitude 7.8 earthquake that hit New Zealand on 14 November – and the sequence of events that followed – has been complex in every sense. The main shock itself was a highly complex rupture of multiple faults that extended northwards and delivered a hefty punch to Wellington, well distant from the putative epicentre. That … More Does the Moon cause earthquakes – or is that a bit looney?

In past decades the usual face of such events were street-scapes of broken buildings and scattered debris, typified by the ruin that struck Napier and Hastings in 1931. That disaster cued more than half a century of active quake-proofing measures, bolstered by … More The modern face of earthquakes in New Zealand
