冰川推进的周期性与火山喷发的发生之间可能存在联系。Lamb1绘制了一张曲线图，显示了自公元870年以来冰岛附近的北冰洋海冰和冰岛大火山喷发的类似曲线。Bray2发现，自公元1680年以来高山冰川最大推进的次数与火山沙尘面纱指数为1,000或更大的时间间隔显著相关(χ2=7.8P<；0.01)。火山尘埃的估计现在已经延长到公元1500年(参考文献)。1)在本文中，我分析了这些估计与公元1500年至今的最大冰川推进记录之间的关系。
THERE may be a connection between the periodicity of glacial advance and the occurrence of volcanic eruptions. Lamb1 has presented a graph which shows a similar curve for Arctic sea ice off Iceland and great Icelandic volcanic eruptions since 870 AD and Bray2 found the number of maximum advances of alpine glaciers since 1680 AD is significantly related (χ2 = 7.8, P < 0.01) to intervals with a volcanic dust veil index of 1,000 or greater. The volcanic dust estimates have now been extended to 1500 AD (ref. 1) and in this paper I analyse the relationship between these estimates and records of maximum glacial advance from 1500 AD to the present.
