A major earthquake rattled much of the southern North Island of New Zealand during the early hours of Tuesday morning – magnitude 5.5. It woke Kiwis from southern Hawke’s Bay to Wellington and was classed as ‘strong’ by our seismologists.
Luckily nobody was hurt, and no damage was reported. Good news in a land where earthquakes are a fact of life. Curiously, it came in the very week my new science book on seismology and earthquakes is being published by Penguin Random House. Living On Shaky Ground: the science and story behind New Zealand’s earthquakes. Good thing I wasn’t writing a book on the zombie apocalypse. Though, scientifically speaking, we get so many earthquakes here that I’d have been surprised if there wasn’t one when the book was released.
That, of course, highights why I wrote it. One of New Zealand’s biggest ongoing issues is earthquakes and the volcanoes and tsunami that go with them. It’s a vital subject – an immediate subject. Certainly that’s true for the long-suffering folk of Christchurch whose city was shaken to pieces, with terrible loss of life, in 2010-11. However, life atop the collision point of major tectonic plates is something that every Kiwi has to come to terms with.
The real issue, of course, is what’s in store for us. That’s something science can tell us – the physics of earthquakes. I’ve looked into that in this book, outlining, for general readers, how the science works, what it’s about, and what we can expect from the scientific understanding. It’s a vital subject – certainly here in New Zealand, where earthquakes are a constant fact of life. And to me, that also makes earthquakes something more than just science. They are also a human phenomenon.
What do I mean? To those living in earthquake zones the real issue is the human reality. Earthquakes are not a nebulous future risk; they are a certainty. The question is not if, but when and how. And to me, the human reality – the way we react to these cataclysms of nature – is as important a focus as the science, and something I’ve built into the book. Underscoring, for me, the point that science – for all that we view it as abstract – is really as much a human endeavour as anything else. Isn’t it.
So how do we react? And what is the science behind earthquakes? I’ve got a few posts coming up on that – though you’ll need to check out the book to get the full story. What I will say, though, is that such events almost always provoke people to find strengths in themselves that, perhaps, they did not know they had. That, to me, is such a wonderful testament to the reality of human nature.
