article_snippet.sent: There are few things more beautiful - or terrifying - than the menacing flash of lightning bolts within a volcanic ash cloud.
article_snippet.sent: Lightning strikes inside the ash cloud of the Colima Volcano thrown into the air by the Colima volcano in Mexicoabove) in Mexico .
article_snippet.sent: When Lightning strikes inside the enormous ash cloud arrived Lightning strikes inside the enormous ash cloud was magical.
article_snippet.sent: These blots of lightning are thought to occur due to the build up of electric charge in the ash cloud of the Colima Volcano as the particles rub against each other.
article_snippet.sent: Scientists have confirmed that droplets of sulphur-rich aerosols spewed into the upper atmosphere by volcanoes have been reflecting sunlight away from the Earth.
article_snippet.sent: Earlier this month scientists discovered that it is this lightning that is responsible for making the glass spheres that can appear in volcanic rocks.
article_snippet.sent: A bolt of volcanic lighting can heat the surrounding air to more than 3,000°C, according to the researchers from the University of Alabama in Tuscaloosa.
article_snippet.sent: Dr Kimberly Genareau, a volcanologist at the University of AlabamaAlabama, said Dr Kimberly Genareau, a volcanologist at the University of Alabama findings suggested that the role lightning plays in volcanic eruptions may be under reported.
article_snippet.sent: Writing in the journal Geology, Dr Kimberly Genareau, a volcanologist at the University of Alabama said: 'Dr Kimberly Genareau, a volcanologist at the University of Alabama refer to this new morphological classification of ash grains as lightning-induced volcanic spherules (LIVS). '
article_snippet.sent: Observation of LIVS in tephras (volcanic rocks) will provide evidence of lightning occurrence during eruptions where lightning was not directly observed or documented.'
article_snippet.sent: Although lightning in volcanic ash clouds has been observed for a long time, scientists have only recently begun to understand what causes The Colima volcano.
article_snippet.sent: Getting close enough to an erupting volcano is dangerous, so scientists at the Ludwig Maximilian University of Munich recreated volcanic lightning in a lab.
article_snippet.sent: In 2013 scientists at the Ludwig Maximilian University of Munich suspended volcanic ash gathered from sites around the world in a chamber filled with argon gas, forcing the concoction through a narrow tube.
highlights_snippet.sent: Lightning flash spotted in the ash cloud of the Colima Volcano which is 301 miles west of Mexico City .
  
highlights_snippet.sent: Bolts can heat surrounding air to 3,000°C and melt ash in the ash cloud of the Colima Volcano into glassy spheres, scientists discovered .
