Such stories. It really must seem like the End Times if you are caught unawares by something as seemingly uncomprehensible (the waters being so dramatically drawn out and then surging back in). But the question can't be escaped, Why weren't more people warned? Once an earthquake occurs, certain things happen, where was the warning of tsunamis?
I'm sure many people are wondering about that.
On Fox News yesterday I saw two experts, one American and one Chinese, explain that
(1) tsunamis in the Indian Ocean are rare, so people are unprepared for them (unlike people in Japan, for instance); and
(2) the kind of sensors that are used to detect seismic and tsunami activity are practically non-existent because they are logistically very hard to place in the Indian Ocean, for some reason I don't remember.
