Explanations: answer key for all 10 questions

Q1: What is volcanic lightning also called?
Answer: A dirty thunderstorm
Ash makes it dirty.
Q2: What helps build electrical charge in ash plumes?
Answer: Colliding ash particles and ice
Friction separates charge.
Q3: Where can small sparks form?
Answer: Near the volcano's vent
Ash is densest there.
Q4: Where does larger lightning often occur?
Answer: High in the plume where ice forms
Plumes reach freezing heights.
Q5: Which Icelandic eruption in 2010 showed dramatic lightning?
Answer: Eyjafjallajökull
It also grounded flights.
Q6: Which Chilean volcano erupted with lightning in 2008?
Answer: Chaitén
Photos became famous.
Q7: Which 2022 eruption produced record-breaking lightning?
Answer: Hunga Tonga-Hunga Ha'apai
It was an underwater volcano.
Q8: What was remarkable about Hunga Tonga's lightning?
Answer: It was the most intense ever recorded
Hundreds of thousands of flashes struck.
Q9: Which ancient writer described lightning at Vesuvius?
Answer: Pliny the Younger
He watched the 79 CE eruption.
Q10: How can volcanic lightning help scientists?
Answer: It helps detect eruptions remotely
Lightning networks spot ash clouds.

Storms Inside an Eruption

Volcanic lightning, nicknamed a dirty thunderstorm, flashes inside ash plumes during powerful eruptions. Colliding ash particles and, higher up, ice crystals separate electrical charge, which builds until it discharges as lightning.

Small sparks can crackle near the vent where ash is densest, while larger bolts strike high in the plume where it reaches freezing heights. Dramatic examples include Eyjafjallajökull in Iceland in 2010 and Chaitén in Chile in 2008. The underwater Hunga Tonga-Hunga Ha'apai eruption in 2022 produced the most intense lightning ever recorded, with hundreds of thousands of flashes.

The Roman writer Pliny the Younger described lightning during the eruption of Vesuvius in 79 CE. Today, global lightning networks help scientists detect eruptions and ash clouds remotely, warning aircraft in time.
