Lightning in volcanic ash
If a volcanic eruption is not impressive enough already, try seeing it when lightning is involved. Normally ash and dust are electrically neutral.

These in turn cause electric and magnetic fields, with the result that the positively and negatively charged ions separate from each other. This process can then add severe lightning to a volcanic ash cloud.
