Earthquakes are virtually unpredictable. But tsunamis happen because of some disturbance that happened hundred/thousands miles away so you can "see" it coming. Didn't they know they were living close to a fault line? - I don't know, maybe they didn't....

>In asia all they had was 100 minutes. How would you save 100k people from drowning on a sunday morning in a non 1st world country with limited infrastructure? Those countries have much more to worry about than losing a couple of thousand citizens and tourists each 100 years because of disasters. It has never been a priority there.


If they have money to build nuclear bombs in India, they have the money to install a simple warning system. Lot of people can be evacuated in couple hours. In this case, all they had to do was to get to higher ground just a few blocks away. How many block can you walk walking four about thirty minutes?


>But you cannot protect yourself from every disaster....

That's right but you can save a lot of lives. You're never going to save 100% of the people. There are always those that ignor the warnings, even in the US fr hurricanes. And you're right it is after the fact. But, it would be tragic if they didn't learn anything from this.
