Geologists and volcanologists making preparations at the Galeras stratovolcano hours before the eruption. The Galeras tragedy occurred when six scientists and three tourists were killed as a result of the January 1993 eruption of the Galeras stratovolcano in Colombia. Geologist Stanley Williams and six others on the volcano survived.
Two major caldera-forming eruptions have occurred, the first about 560,000 years ago in an eruption which expelled about 15 cubic kilometres (3.6 cu mi) of material. The second some time between 40,000 and 150,000 years ago, in a smaller but still sizable eruption of 2 cubic kilometres (0.48 cu mi) of material.

The mega explosions are powerful enough to lay an entire planet to waste.
Known large eruptions after the Paleogene period (from 66 Mya to 23 Mya) are listed, especially those relating to the Yellowstone hotspot, Santorini caldera, and the Taupō Volcanic Zone. Active volcanoes such as Stromboli, Mount Etna and Kīlauea do not appear on this list, but some back-arc basin volcanoes that generated calderas do appear ...
The eruption occurred at the height of guerrilla warfare in Bogotá, and so the government and army were preoccupied at the time of the eruption. [16] Only a few buildings and structures remained standing after the mud and debris flows ravaged the town of Armero. The day after the eruption, relief workers in Armero were appalled at its impact.
The eruption poured over 17 million tons of the gas into the atmosphere and led to a global temperature decrease of around 0.5 degrees Celsius (0.9 degrees Fahrenheit) that lasted about a year ...
