Supersized Earth - La Garita Caldera - Netflix

La Garita Caldera is a large volcanic caldera in the San Juan volcanic field in the San Juan Mountains near the town of Creede in southwestern Colorado, United States. It is west of La Garita, Colorado. The eruption that created the La Garita Caldera is among the largest known volcanic eruptions in Earth's history.

The scale of La Garita volcanism was the second greatest of the Cenozoic Era. The resulting Fish Canyon Tuff has a volume of approximately 1,200 cubic miles (5,000 km3), rating it an 8 on the Volcanic Explosivity Index. By comparison, the May 18, 1980, eruption of Mt. St. Helens was 0.25 cubic miles (1.0 km3) in volume. By contrast, the most powerful human-made explosive device ever detonated, the Tsar Bomba, had a yield of 50 megatons, whereas the eruption at La Garita was about 5,000 times more energetic. However, because Tsar Bomba's reaction was complete within microseconds, while a volcanic explosion can take seconds or minutes, the power of the events are comparable if measured within the respective bounded timeframes. It is the most energetic event to have taken place on Earth since the Chicxulub impact which, at 240 teratons, was approximately one thousand times more powerful than La Garita.
