Volcanic lightning arises from colliding, fragmenting particles of volcanic ash (and sometimes ice), [1] [2] which generate static electricity within the volcanic plume, [3] leading to the name dirty thunderstorm. [4] [5] Moist convection currents and ice formation also drive the eruption plume dynamics [6] [7] and can trigger volcanic lightning.
Volcanic material thrust high into the atmosphere can trigger lightning. Volcanic activity produces lightning-friendly conditions in multiple ways. The enormous quantity of pulverized material and gases explosively ejected into the atmosphere creates a dense plume of particles.
Evidence of lightning activity can often be found in the paleomagnetic record. Lightning strikes are the result of tremendous charge buildup in clouds. This excess charge is transferred to the ground via lightning channels, which carry a strong electric current. Because of the intensity of this electric current, when lightning hits the ground ...
By RYAN GORMAN Recently released images show the stunning moment lightning bolts shot across a massive ash cloud emanating from an Indonesian volcano. The shock lightning occurred nearly one year ...
The Earth is struck by lightning nearly 20 million times each year, and bolts of lightning can travel as much as 10 to 12 miles from a thunderstorm, instantly heating the air to 50,000 degrees ...
JAKARTA (Reuters) -Indonesia's Ruang volcano erupted on Tuesday, spewing lava as lightning flashes lit up its crater, prompting authorities to raise the alert status and evacuate more than 12,000 ...
Roger Clark, lecturer in geophysics at Leeds University said in the journal Nature in 1996, responding to a newspaper report that there had been two secret Soviet programs, "Mercury" and "Volcano", aimed at developing a "tectonic weapon" that could set off earthquakes from great distance by manipulating electromagnetism, said "We don't think it is impossible, or wrong, but past experience ...
Reports say that this volcanic eruption could trigger an ice age from the sheet of ash that not even the sun could stand a chance of penetrating. 'High threat' supervolcano could bring about an ...
