Strange thing, you know; since the Big Tsunami in the Indian Ocean on December 27 2006 (my birthday, as it happened) everyone has got all concerned.
It's fairly obvious that, on an island like Siargao, where most of the flat ground is only 1 or 2 metres above high-tide mark, that, if a tsunami happened, we'd all be done for.
A tsunami's not something you can plan ahead for.
We're only a few miles from the Philippine Deep (some 10km down), and if, say, a huge submarine landslide or something similar happened there, we wouldn't have much time to run.
So there's not much point in putting up notices like this, especially when it's distinctly ambiguous about whether you have to run 14 kilometres or just a mile.
So, it may happen at any time, and since I can't run much any more, I'll just plod along, and pray (even though I'm an atheist).
