Hurricanes hardly happen, Henry Higgins assures us in My Fair Lady, Lerner and Loewe’s great musical adaptation of Bernard Shaw’s play Pygmalion. Obviously, Alan Jay Lerner (the lyricist), never went to Florida, where hurricanes are positively ubiquitous. The coverage in our media is immense, the footage graphic, the consequences dire.

To obliterate a mountain, one must first drill a series of holes 2.4 metres deep – in either a square or diagonal pattern, depending on the rock type and face condition. A crew moves in to load the holes with blasting agent, typically a mix of ammonium nitrate and fuel oil. Detonators and boosters are laid and an explosive cord is run over the mountain face. A fuse is lit. It explodes the detonator, which explodes the cord, which explodes the boosters, which explodes the blast mix, which in turn explodes the mountain.
