OK, just click this and hang on:
Did you jump? I certainly did. Seeing that tree obliterated in an instant is certainly sobering.
According to meteorologist Brad Panovich of NBC Charlotte (thanks for the tip!), trees exploding due to lightning "is actually quite common. The explosion is usually due to the lightning superheating the sap or moisture in the tree causing a steam explosion. This is often why the bark is blown off in all directions when a tree gets hit."
This is apparently in Sweden, as "blixtnedslag" is Swedish for lightning.
So far this year, lightning has killed 20 Americans, according to the National Weather Service.
