Hurricane Damage: Our Fault?

Last week Hurricane Isabel breezed in to North Carolina, Virginia, and other states and caused massive power outages that may take two weeks to fix in some cases. At least this is not like Planeattack where we can say that some group of people caused it. It was a perfectly natural event; a windstorm with 40-60 mph winds that caused a lot of damage to this area. Or was it completely natural?

60 mph winds should not cause that much damage! Just how did Isabel wreak such destruction with only gale-force winds? Firstly, note that just about all damage due to Isabel was due to trees falling down on things: power lines, homes, cars, trailers. Almost none of it in central Virginia was due to direct effects of the winds. Only on the Outer Banks and surrounding areas did that occur. Second, take a look around the neighborhood. Go through the streets and go into the woods. What do you find? Trees that are all by themselves are the ones that fell. Trees that are with other trees are less likely to have fallen. If you go into the forest you find that almost all trees are intact. If there is a wide path through the woods, the path is probably impassable with fallen trees, but the forest is just as before. It is just like it was before the hurricane. It is easy to see why that is the case. Trees around other trees are not subject to the same winds as trees all by themselves, because they protect each other Trees on the edge are more likely to get knocked down by the winds, and isolated trees are even more likely.

Which brings up a human cause for the damage: the developers. The developers, it seems, don't care anything about who lives in the houses afterwards. They just want to throw up houses quick, chop down trees quick, collect their bucks, and leave isolated trees to fall during hurricanes. When building houses, developers need to either leave no trees in the yard or a continuous area of them. If they leave isolated trees, they leave bombs which later on damage the homes they build. So it is not all nature's fault. The developers had a hand in it, too.
