Hard to tell in the various shots how much eruption has already taken place, but at least some of the lightning might be generated by the volcano itself. Static electricity from the erupting particles causes lightning, which is known as volcanic lightning or a dirty thunderstorm.
The volcano is very likely causing the thunderstorm. Thunderstorms develop when convective activity pushes hot, moist air to high altitude. The high heat from the volcano very likely induces the convective flow necessary to generate the storm.

Those both sound like really good names for drinks.
