The dominantly andesitic volcano has been active for more than 1 million years, and two major caldera collapse eruptions took place during the past 100,000 years. [1] Two major caldera -forming eruptions have occurred: the first was about 560,000 years ago in an eruption which expelled about 15 cubic kilometres (3.6 cu mi) of material. [4], Elements in the media made the event controversial by suggesting the expedition leader, geologist Stanley Williams, who survived along with four others, had ignored safety procedures. These have occurred before about eighty percent (80%) of the explosions at Galeras, and the number of tornillo events recorded before an eruption is also correlated with the size of the eruption that followed.
