On 19 September 2021, the earth opened up on the Atlantic island of La Palma. What followed was the longest volcanic eruption in the island’s history - and an impressive demonstration of Nature’s destructive power. Spawned by fire: On 19 September 2021, the earth opened up on the Atlantic island of La Palma. What followed was the longest volcanic eruption in the island’s history - and a rare opportunity for scientists to watch evolution at work. For almost three months, the volcano high on the island’s Cumbre Vieja ridge gushed gigantic chunks of pyroclastic material, lava and ash. At times, several lava flows moved downslope at a speed of 120 meters per hour. Anything in their way was destroyed and buried under a layer of lava up to 60 meters thick. The documentary charts the scientific work carried out on the volcano from the first day of the eruption.
