I know what you're trying to say, but get a clue, man. With your perspective and whacked reasoning so lacking of any sense of sympathy, I suppose everyone in SanFrancisco should pack up and leave, because they're living under a serious threat of earthquakes. Likewise, anyone along the southeast coast should move to avoid hurricanes. For that matter, anyone along the coasts should move because of tsunami danger. Seattle people should get out of there because Rainier could erupt and send out a deadly lahar flow. No one should live in the midwest because of the tornado dangers. When tens of thousands die from monsoons in Southeast Asia because they live in low-lying areas, they should have seen it coming.
You know what? Most places--especially cool places--have some element of natural danger. Yes, people knew there was potential for devastation living in the forests of Tahoe. But they simply hope nothing like this will happen, and that all steps will be taken to prevent it. What's your solution? Clear cut everything on the lake?
Find me a place that's completely safe from avalanches, floods, fire, earthquakes, whatever nature can dish out, and I'll see a place that's probably boring as hell. If that's where you live, well, I have some sympathy for you.
