What is causing the electrical charge in this one?

It's volcanic lightening Lois and not very well understood. Particles in the air become charged .. Idealized sequence of events that leads to lightning 1. Starting state (particles might have already been charged by some previous process). 2. Collisions lead to charge separation. For this to happen there has to be some difference in the electrical properties of the particles in the collisions. 3. Some process, such as aerodynamic sorting, segregates the positively and negatively charged particles. This means that there are sections of the cloud that are more negative or positive than other sections. 4. When the charge separation becomes too great, electricity will flow between the positive and negative regions of the cloud forming lightning and neutralizing the charge separation. I found this on geology.com geology.com/articles/volcanic-lightning/it also has some amazing photos of volcanic lightening
