what caused this?
This sort of damage is usually caused by a loose connection, either a bad crimp, or loose on the terminal. When loose you get arcing and oxidation on the contact, the resulting resistance creates heat while the current is flowing, this creates more oxidation and more resistance, things can get hot.
I have run into this sort of failure many times over the years.
