Volcanic Lightning: Why is it Different?

In summary, it is believed that the static electricity generated during a volcanic eruption is similar to that in a thundercloud, making the volcano a more effective lightning producer due to the dust. The cause of the different colors of volcanic lightning is uncertain, but it may be due to the gases or ash surrounding the volcano. A stunning series of photos shows the various types and colors of volcanic lightning, which can also resemble mythical creatures. It is noted that the lightning in a volcano is not necessarily a different color from that in a thunderstorm, as it is affected by similar factors such as rain or ash.

so why is there lightning in a volcanic eruption? why is the lightning a different color? maybe we could make these eruptions on purpose or similar scenarios to make lightning? thanks for you input!

The static electricity generated as the dust an gas is ejected up at high speed is very similair to that in a thundercloud. The volcano is rather more effective because of the dust.
I don't know if it would be a different colour other than possibly filtering through the gas cloud surrounding the volcano, or possibly from burning some of the gases.

Stunning series of professional grade photos showing showing mammoth electrical arcs, glows, corkscrews, "tadpoles", globules and various other lightning discharge effects in a wide variety of colors. Also seen are ash clouds resembling mammatus clouds. It's easy to see how the mythic imagination could find dragons and firebirds in these images.

Respectfully submitted,

This thread is over two years old but I must say these photos are amazing.

hey Steve

thanks for posting that link :) truly stunning series of pics

as can be seen the lightning isn't a different colour just because its assoc with a volcano.
those strokes out in front of the ashcloud are still blue/white, just like in a thunderstorm.

only those partially obscurred by the ash are dulled in colour to reds etc
the same thing happens in storms when the lightning is partially hidden by heavy rain bands or cloud

the only difference between lightning production in storms and volcanoes is...
rain droplets carrying charges upwards, compared to ash particles.

cheers

1. What causes volcanic lightning?

Volcanic lightning is caused by the buildup of static electricity within the ash plume of a volcanic eruption. As the ash particles rub against each other and the surrounding air, they create an electrical charge, leading to lightning bolts.

2. How is volcanic lightning different from regular lightning?

Volcanic lightning is different from regular lightning in several ways. Firstly, it is generated by a volcanic eruption rather than a thunderstorm. Secondly, it tends to be more frequent and more powerful, with bolts reaching up to 10 times the length of regular lightning bolts. Lastly, volcanic lightning is often accompanied by other unique phenomena such as volcanic thunder and ball lightning.

3. Is volcanic lightning dangerous?

While volcanic lightning can be a spectacular sight, it is generally not considered dangerous for those observing from a safe distance. However, it can pose a risk to pilots flying near an erupting volcano, as the lightning bolts can interfere with aircraft navigation systems.

4. Can volcanic lightning be predicted?

Currently, there is no reliable way to predict when and where volcanic lightning will occur. However, scientists are studying the phenomenon in hopes of developing methods for predicting and monitoring volcanic activity, which could potentially include volcanic lightning.

5. What can we learn from studying volcanic lightning?

Studying volcanic lightning can provide valuable insights into the behavior of volcanic eruptions. By analyzing the frequency and characteristics of volcanic lightning, scientists can better understand the internal processes of a volcano and potentially improve eruption forecasting. Additionally, studying volcanic lightning can also help us understand the role of electricity in other natural phenomena and how it may impact our planet.
