Any idea on how long after the quake it took the tsunamis to hit? Had evacuations started?
You got me, I'm still trying to convert time zones and catch up. From what I understand, these waves can move pretty fast, depending a number of variables.
I'm unaware of any evacuations taking place anywhere in the Indian Ocean. There's no tsunami warning infrastructure or network. These tsunamis hit probably 1-3 hours after the quake in most places. Places like Sri Lanka probably felt very limited shaking due to distance from the epicenter. Only warning you get is the water going out before it comes in.
