Document Summary

By carbon 14 dating of buried, burnt wood. Airborn ash gets into airplane engines and damages/stops them. Thin ashfall layer (10-15 cm) can cause roof to collapse, especially if water is present. Very thin ashfall layer (less than 1cm) can disrupt agriculture. Intake of ash affects industry (hydroelectric and nuclear power stations) Highest asking price for a sack of flour (shillings): 1815 june 65 nov 58 year of eruption. * we only think we escape islands; we forget wind, which blows spores and ashes from all over he planet to keep us good company . Travel downslope at up to 150km/h: pyroclastic surge (lateral blast) Same amount of force as an atomic bomb. Magma puhes against side of volcano and creates bulge.
