If we use the last 20 years for trend, then: Yr, Number 2035 96.8 2030 92.2 2025 87.6 2020 83 2015 78.4 2010 73.8 If between 150 year trend and last 20 year trend, then: Yr, Number 2035 between 70 and 97 volcano eruptions 2030 between 68 and 92 volcano eruptions 2025 between 67 and 88 volcano eruptions 2020 between 66 and 84 volcano eruptions 2015 between 64 and 78 volcano eruptions 2010 between 63 and 74 volcano eruptions All trends point to increased vulcanism in the next 30 years. Year 2005 eruption frequency is statistically aberrant from the past 150 years, p < .05 Something is up... [/quote]
