Volcanic lightning: global observations and constraints on source mechanisms

  author={Stephen R. McNutt and Earle R. Williams},
  journal={Bulletin of Volcanology},
Lightning and electrification at volcanoes are important because they represent a hazard in their own right, they are a component of the global electrical circuit, and because they contribute to ash particle aggregation and modification within ash plumes. The role of water substance (water in all forms) in particular has not been well studied. Here data are presented from a comprehensive global database of volcanic lightning. Lightning has been documented at 80 volcanoes in association with 212…

Using lightning observations as a volcanic eruption monitoring tool
Lightning commonly occurs in the eruption columns produced by explosive volcanic eruptions. There are several different kinds of lightning detection instruments that could be employed to help monitor
Chapter 62 – Volcanic Lightning
Charge mechanism of volcanic lightning revealed during the 2010 eruption of Eyjafjallajökull
[1] Volcanic lightning has intrigued observers through the centuries. Several likely processes have been proposed to explain the electrification of volcanic plumes, including quenching magma-water
The Elusive Evidence of Volcanic Lightning
Using laboratory high-current impulse experiments, this research shows that within the lightning discharge channel there is an ideal melting zone that represents roughly 10% or less of the total channel radius at which temperatures are sufficient to melt the ash, regardless of peak current.
Lightning-induced volcanic spherules
Glass spherules have been documented in many geologic deposits and are formed during high-temperature processes that include cloud-to-ground lightning strikes, volcanic eruptions of low-viscosity
Volcanic lightning as a source of reactive radical species in eruption plumes
Volcanic lightning has accompanied most recent major explosive eruptions and provides a source of intense thermal energy to drive the formation of reactive radical species. These radicals may have an
Search for possible relationship between volcanic ash particles and thunderstorm lightning activity
Explosive volcanic eruptions that eject columns of ash from the crater often generate lightning discharges strong enough to be remotely located by very low frequency radio waves. A fraction of
Impulsive Volcanic Plumes Generate Volcanic Lightning and Vent Discharges: A Statistical Analysis of Sakurajima Volcano in 2015
The origin of electrical activity accompanying volcanic ash plumes is an area of heightened interest in volcanology. However, it is unclear how intense an eruption needs to be to produce lightning


Electrification of volcanic plumes
Volcanic lightning, perhaps the most spectacular consequence of the electrification of volcanic plumes, has been implicated in the origin of life on Earth, and may also exist in other planetary

Ice in the 1994 Rabaul eruption cloud: implications for volcano hazard and atmospheric effects
VOLCANIC clouds are an important natural hazard to aircraft1, and host chemical reactions that interest both volcanologists2,3 and atmospheric scientists4-6. Ice has been suggested as a possible

Electrical Charging of Volcanic Plumes
Many explosive terrestrial volcanic eruptions are accompanied by lightning and other atmospheric electrical phenomena. The plumes produced generate large perturbations in the surface atmospheric
Three distinct regimes of volcanic tremor associated with the eruption of Shishaldin Volcano, Alaska 1999
Abstract.Tremor signals associated with the eruption of Shishaldin Volcano on 19 and 23 April 1999 were the strongest recorded anywhere in the Aleutian Arc by the Alaska Volcano Observatory (AVO) in
Electrical Activity During the 2006 Mount St. Augustine Volcanic Eruptions
The fact that the lightning onset was delayed and continued after and well downwind of the eruption indicates that in situ charging of some kind was occurring, presumably similar in some respects to that which occurs in normal thunderstorms.
Ice nucleation and overseeding of ice in volcanic clouds
[1] Water is the dominant component of volcanic gas emissions, and water phase transformations, including the formation of ice, can be significant in the dynamics of volcanic clouds. The
Total Water Contents in Volcanic Eruption Clouds and Implications for Electrification and Lightning
The behavior of water in magma in the Earth is fairly well understood in volcanology, and the behavior of water in the atmosphere is decently understood in meteorology. This study tries to bridge the
A Parametric Study of the January 2006 Explosive Eruptions of Augustine Volcano, Alaska, Using Seismic, Infrasonic, and Lightning Data
A series of 13 explosive eruptions occurred at Augustine Volcano, Alaska, from January 11-28, 2006. Each lasted 2.5 to 19 minutes and produced ash columns 3.8 to 13.5 km above mean sea level. We
