I've just spent an enjoyable week on holiday in Taupō celebrating my 50th birthday. It's amazing to think that this massive lake is actually the caldera of a supervolcano that, for the last 30,000 years or so, has erupted on average around once every thousand years, and that it last erupted about 1,800 years ago. Staying in a property overlooking the lake certainly made me think a little about my own mortality, and my family's wellbeing. Given that, according to Wikipedia, the last eruption “devastated much of the North Island”, I guess it's more than just the local residents who will be affected when the volcano next erupts.

Few could have had any idea, on that New Year's Day of a century ago, of what the next few years would bring.
