Whilst I was living in Christchurch (NZ) I was struck by how relatively blasé the locals were about living on the Ring of Fire.
Admittedly, procedures were in place in the event of a geological hiccup and low-rise building is very much the norm. However, a heck of a lot of that building was on top of cliffs, underneath cliffs or on soft, easily liquified ground. A couple of locals who visited my home were thoughtful enough to take the piss out of the month's supply of tinned food I had sitting in a cupboard.
The thing is, whilst tsunamis were seen as being very much on the cards, few people believed that Christchurch would ever be hit by a major earthquake - what with the nearest seismic fault being 80 or so miles away
Only, as it turns out, Christchurch sits directly, and I mean directly, on top of a major, previously dormant, fault and it hasn't stopped rumbling since it kicked off all of a sudden last September
Being a curious soul I've been wondering ever since how it is that a significant rupture in the Earth's crust would burst into life after being quiet for at least thousands of years?
The answer could have been, and still could be, a stochastic 'shit just happens' explanation and what happened to Christchurch is a localised one-off event with no systemic implications for anywhere else
However, some on-line Earthquake buffs (e.g.) have been suggesting that there is a spike in global seismic activity which has been building up over the last 2-3 years. The problem with knowing if they're onto something or not is the risk that these doom-sayers could be indulging in the kind of subjective, dot-joining based activities that veteran conspiraloons know and love
And then this chap posted this vaguely-frantic video a couple of days ago...
