Within the first couple days of the Indonesian quake/tsunami six(ish) years ago, death tolls over 100,000 were being reported (final count was over 200,000).
Within the first couple days of the Japanese quake/tsunami, death tolls in the hundreds were being reported. (Of course, we're not done yet.)
The difference in ability to predict and effectively react between wealthy and poor nations is striking. Three orders of magnitude? Yikes. We in the better-off nations usually send aid after the fact, but it really makes me wonder what we could do before the fact to help less-developed nations build better defenses.
