My first thought when I woke up this morning was that the subway, here in Port Vila, is pretty intense. It took me maybe 20 seconds to realize that the shaking was from an earthquake! Such an absurd feeling that I was not even thinking that there is no subway (or any rail-tracks) of any kind here :).
Anyway, quite impressive stuff... people just kinda came out of their homes and waited, but no one was really scared. 10 minutes later, again... this time slightly weaker. They lasted for a long time, I never experienced anything like this. Maybe around 30-40 seconds each of them.
Seems like it was between 5.4 and 5.8, the first one, according to different reports and the other one around 4.8 (on Richter scale).
So the explanation I got was that the volcano in the island of Ambrym was messing around, but nothing serious and no need to evacuate populations. The epicenter was around 100 km from Port Vila, where we are now.
Well, I guess that is what you get when you come to a place which is basically a bunch of volcanoes :)
The sensation though, really unforgettable... everything just shaking... hard enough to wake me up, which is not really an east feat!
