Abstract
Analysis of the frequency-size relationship of explosive volcanic erup tions for the past 2000 years reveals that the time-averaged eruptive mass flux of tephra from subaerial explosive eruptions is 3x10(4) kg s (-1). This mass flux corresponds to a thermal energy release of 4x10(1 0) W. Half of the long-term (>10(3) year) mass and thermal energy rele ase from explosive volcanic eruptions is accounted for by eruptions of >10 km(3) of tephra.
