Data shows the thousands of lightning strikes that accompanied the volcanic eruption.
The dramatic volcanic eruption on a remote island in Indonesia's North Sulawesi province on April 17 threw a fiery-red column of lava, incandescent rock and ash as much as 3 km into the sky.
Scientists are still studying the behavior of volcanic lightning. "Each of these eruptions that produce lightning helps us better understand what is happening in the eruptive plume and helps us understand our planet better," said Chris Vagasky, a meteorologist at the University of Wisconsin-Madison.Despite the striking visuals, the amount of lightning during the Ruang eruption pales in comparison to the massive Hunga Tonga-Hunga Ha'apai eruption in Tonga in 2022.
Although caused by different materials in the atmosphere, volcanic lightning and that from a typical thunderstorm are both a result of particles becoming charged. When there are large positive and negative charge build-ups in the atmosphere, electrons flow between them, causing lightning.The other way lightning can occur, in eruptions with tall plumes of 7-12 km, is via a mechanism called “ice charging” as the plume reaches heights where water can freeze.
