Snow and ice perturbation during historical volcanic eruptions and the formation of lahars and floods
@article{Major1989SnowAI, title={Snow and ice perturbation during historical volcanic eruptions and the formation of lahars and floods}, author={Jon J. Major and Christopher G. Newhall}, journal={Bulletin of Volcanology}, year={1989}, volume={52}, pages={1-27} }
Historical eruptions have produced lahars and floods by perturbing snow and ice at more than 40 volcanoes worldwide. Most of these volcanoes are located at latitudes higher than 35°; those at lower latitudes reach altitudes generally above 4000 m. Volcanic events can perturb mantles of snow and ice in at least five ways: (1) scouring and melting by flowing pyroclastic debris or blasts of hot gases and pyroclastic debris, (2) surficial melting by lava flows, (3) basal melting of glacial ice or…
