claim: A video shows a bolt of lightning striking a river, sparking a large explosion.
origin: In July 2017, a video purportedly showing â€œa bolt of lightning striking a riverâ€ went viral on social media:Â < This is crazy! One of the most amazing things Iâ€™ve ever seen with lightning. Almost doesnâ€™t look real! If you arenâ€™t terrified of lightning in a swimming pool, you will be now! > This video, however, does not actually show a bolt of lightning striking a river. When the video is slowed down, it is easy to tell that the â€œlightningâ€ strike doesnâ€™t come from the sky, but from a wire on the hill. Hereâ€™s a screenshot showing the moment of impact (which can be glimpsed at the 7-second mark in the video above): < KÃ„Ã„NNY VEDENALAISESSA LOUHINTA JA RÃ„JÃ„YTYSTYÃ–SSÃ„ AINA ASIANTUNTIJAN PUOLEEN Rantojen ja vedenalaisen kallion louhinta- ja rakennustyÃ¶ Turun saaristossa ja ympÃ¤ristÃ¶ssÃ¤. Vedenalaisessa louhinnassa madalletaan kallionpinnan korkeutta jÃ¤rvessÃ¤, meressÃ¤ tai muussa vesistÃ¶ssÃ¤. Ennen louhintatyÃ¶n aloittamista tehdÃ¤Ã¤n louhinta- ja rÃ¤jÃ¤ytystÃ¶iden suunnitelma, jotta kaikki toteutuu turvallisesti. VesistÃ¶ssÃ¤ tapahtuva kallion louhinta on luvanvaraista toimintaa ja saattaa vaatia aluehallintoviraston (AVI) luvan. MIHIN VEDENALAINEN LOUHINTA SOVELTUU? Vedenalaista louhintaa kÃ¤ytetÃ¤Ã¤n rantojen ja vesistÃ¶jen kunnostukseen sekÃ¤ merimerkkien perustamiseen. LisÃ¤ksi vesivÃ¤ylien syventÃ¤minen, rakentaminen ja yllÃ¤pito tehdÃ¤Ã¤n louhinta- ja rÃ¤jÃ¤ytystÃ¶illÃ¤. Louhinta suoritetaan laittamalla porausreikiin vedenalaista erikoisrÃ¤jÃ¤hdettÃ¤, joka upotetaan kallioon porattuihin reikiin. Asiakkaita voi olla yksityiset asiakkaat, satamat, ja venesatamat. TAKE SUBMERGED MINING AND BLASTING WORK TO AN EXPERT Mining and construction of beaches and underwater rock in Turku archipelago and surroundings.Â Underwater quarrying lowers the rock surface level in the lake, ocean or other waters.Â Before the excavation work is started, a mining and blasting plan is planned to ensure that everything is safely accomplished.Â The rock mining in water is licensed and may require the permission of the regional government agency (AVI).Â WHERE IS UNDERWATER MINING SUITABLE? Underwater quarrying is used for the refurbishment of beaches and waterways and the creation of sea symbols.Â In addition, the deepening, construction and maintenance of waterways are carried out in mining and blasting operations.Â Extraction is carried out by inserting underwater special explosives into the drilling holes, which are immersed in drilled holes in the rock.Â Customers can be private customers, ports, and marinas. > As several pieces of debris can be seen floating in the river shortly after the explosion, it seems most likely that Rannikon MerityÃ¶ used a detonation cord to dislodge a stump or a tree from the river. Regardless of the exact reason for this explosion, itâ€™s clear that this video shows the work of a dredging company, not a bolt of lightning.Â Meteorologist Skoff later updated his Facebook post to note that the video did not actually show a bolt of lightning striking a river: < This is crazy! Itâ€™s not lightning, BUT instead a detonation cord! There is no flash from the clouds & the bolt just seems to come from the top of the hill. They probably had some explosives detonate under water. Still cool though. > A similar explosion can be seen in the following video showing the removal of the City Mill Dam in the U.S. state of Georgiaâ€™s Chattahoochee River. An almost identical â€œlightning boltâ€ can be seen flashing across the water at the 1:30 mark: Â
