Table 1 The minimum and maximum magnitude values for each VEI classification in the LaMEVE database as well as the mean magnitude with associated variance

From: Global database on large magnitude explosive volcanic eruptions (LaMEVE)

VEI Count Min. mag. Max. mag. Mean mag. Variance
4 595 4 6 4.4 0.14
5 533 4.4 6.9 5.3 0.13
6 258 5 7.5 6.3 0.13
7 107 5.9 8.4 7.2 0.14
8 21 7.8 8.8 8.2 0.06
  1. The mean magnitude value is entered as an estimate of magnitude when only VEI is reported.
