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. However, when the two elements are emanating from a volcano they are (obviously) very hot, and can have positively and negatively charged ions. 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.

More National Geographic photographer Aaron Huey travels back to Svanetia, a remote region of Georgia, to revisit the people and the place that inspired his future career. Re-reading journals full of recipes, songs, and vocabulary he learned on his first visit, Huey talks about the family that took him in when he first arrived. “The whole family still sings in the kitchen. There are just some of those things that never change, and I found a lot of those again.” Huey discovers many similar scenes on his return, such as traditional Svan singers and dancers, in a place few have witnessed.
