Volcanic lightning is an electrical discharge caused by a volcanic eruption rather than from an ordinary thunderstorm.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.
Lightning causes thunder, a sound from the shock wave which develops as gases in the vicinity of the discharge experience a sudden increase in pressure. Lightning occurs commonly during thunderstorms as well as other types of energetic weather systems, but volcanic lightning can also occur during volcanic eruptions.
An earthquake light also known as earthquake lightning or earthquake flash is a luminous optical phenomenon that appears in the sky at or near areas of tectonic stress, seismic activity, or volcanic eruptions. [1] There is no broad consensus as to the causes of the phenomenon (or phenomena) involved.
“Most of what happens at volcanoes is close by, and that’s why you try to keep people away because things happen fast, but lahars can travel a long way from the volcano and have a big impact.”
Indonesia's Ruang volcano erupted several times on Tuesday with a blaze of lightning and lava. Seven airports in the area were closed, as ash had reached eastern Malaysia's airspace, CNN said ...
The event greatly alarmed volcanologists and other scientists around the world—if we couldn’t properly predict when a volcano might erupt, how wou We Now Know Why This Deadly Volcano Erupted ...
The sudden discharge of electrical charges accumulated in the air around the ascending column of volcanic ashes also often causes lightning strikes, as depicted by the English geologist George Julius Poulett Scrope in his painting of 1822 or observed during 2022 Hunga Tonga–Hunga Ha'apai eruption and tsunami.

Sheet lightning is cloud-to-cloud lightning that exhibits a diffuse brightening of the surface of a cloud, caused by the actual discharge path being hidden or too far away. The lightning itself cannot be seen by the spectator, so it appears as only a flash, or a sheet of light. The lightning may be too far away to discern individual flashes.
