Possible Influence of Solar Activity on Global Volcanicity

Lihua Ma, Zhiqiang Yin, Yanben Han


Solar activity has been found to be strongly correlated with some geophysical processes on the Earth system. In the present paper, using global dust veil index of volcanic eruptions and sunspot numbers indicating solar activity, the authors investigate the possible influence of solar activity on global volcanicity during 1700–1995. Results of wavelet analysis indicate that variations of global volcanicity have remarkable temporal characteristics, and it is high related to solar activity on about 11-year cycle, with exceeding the 5% statistical significance level against red noise.
