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 is the major natural cause of wildfire, [175] estimated to cause 10% of forest fires worldwide. [176] Wildfire can contribute to climate change. [ 177 ] Because wildfires emit greenhouse gases, and also affect vegetation cover (which affects how much sunlight is reflected), a lightning wildfire feedback is possible.
The study also speculated that an isolated cause for the lightning might be the presence of uranium in the bedrock. [11] Between 1997 and 2000, a series of four studies proposed that the methane produced by the swamps and the massive oil deposits in the area were a major cause of the phenomenon. [12]
Super volcano is the term used to describe volcanoes that have gradually over time built up immense amounts of magma and could wreak havoc if ejected onto the planet's surface. And in the heart of ...

“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.”
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.

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.
