By combining tree-ring records with emissions data, researchers created model simulations of the 1257 CE Mount Samalas eruption in Indonesia, which produced the largest known stratospheric injection of volcanic gases in the Common Era, and found that as little as 1% of halogen released from the eruption reached the stratosphere; however, the findings suggest that even this small amount of halogen may have resulted in substantial ozone depletion, according to the authors.
