    it is real,the volcanic ash gets charged and causes it's own lightning in the ash cloud,pretty cool for sure,they talked about that on the news tonight.

    The lighting in volcanic plumes is connected to the rotation that these plumes undergo, something like a tornado. As a plume rotates, it can spawn waterspouts or dust devils, which gather together the electric charges in the plume to form a sheath of lightning.

    For both of these eruptions, the lightning did not begin until several minutes after the explosion began. How lightning forms in general is still debated among scientists, and volcanic lightning is even less well understood. What is mostly agreed upon is that the process starts when particles separate, either after a collision or when a larger particle breaks in two. Then some difference in the aerodynamics of these particles causes the positively charged particles to be systematically separated from the negatively charged particles. Lightning is the electrical flow that results when this charge separation becomes too great for air to resist the flow of electricity. Some of the lighting strokes in these photos are at least 2 miles long, so the separation of charged particles must occur on this scale.
