From the page: Explanation: Why does a volcanic eruption sometimes create lightning? Pictured above, the Sakurajima volcano in southern Japan was caught erupting early last month. Magma bubbles so hot they glow shoot away as liquid rock bursts through the Earth's surface from below. The above image is particularly notable, however, for the lightning bolts caught near the volcano's summit. Why lightning occurs even in common thunderstorms remains a topic of research, and the cause of volcanic lightning is even less clear. Surely, lightning bolts help quench areas of opposite but separated electric charges. One hypothesis holds that catapulting magma bubbles or volcanic ash are themselves electrically charged, and by their motion create these separated areas. Other volcanic lightning episodes may be facilitated by charge-inducing collisions in volcanic dust. Lightning is usually occurring somewhere on Earth, typically over 40 times each second.

@gloriabell The person that sent it to you might have deleted it.
In the past week, business has taken me to Vancouver, BC and San Jose, Costa Rica with a pit stop in South Florida for a day or so at home. None of that was a big deal until my colleague Mike Atkin noted at dinner that we've been hitting these spots...

I'm going to go out on a limb here and guess that you think your mother, or perhaps mothers in general, are pretty goddamn awesome. They scrub things, cook pot roast, and produce shrieking little babies which grow up to be astronauts and prime ministers.
