The World’s Worst Oil Spills

The Ten Worst Oil Spills In History.

The World’s Ten Worst Oil Spills

Since one purpose of this site is to put disasters into perspective, I’ll note that in spite of all the hand-wringing about man-made oil spills, the worst culprit is nature herself. Natural oil leaks form the ocean floor annually spill many times more than the amount lost from broken tankers and destroyed rigs. Off the coast of Santa Barbara, for example, there is a naturally occurring leak that seeps 20 – 25 tons of oil each day, and has done so for several hundred thousand years. Department of Energy studies on this, and on other leaks, conclude that each year, more than 47 million gallons leak naturally into US waters. Compare that to the number eleven spill on this list, which was a one-time loss of 45 million gallons.

All that said, here are the Top Ten Worst Oil Spills.
