32 years ago Mount St. Helens , a volcano in Washington state, erupted in a cataclysmic explosion that devastated hundreds of square miles around it, killed 57 people and caused over a billion dollars worth of damage.
A well-known idiom tells us that 'Mother Nature abhors a vacuum'. She's certainly been working hard to repair the damage caused by the eruption. Here's a time-lapse video clip from NASA, showing Landsat images of the area over the 33-year period from shortly before the explosion until the present time. I recommend watching it in full-screen mode. Note how vegetation has returned to most of the devastated area over time, and the changing shape of the lakes in the area as volcanic ash was blown away and/or re-deposited by wind.
Fascinating, isn't it?
