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
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

The mean magnitude value is entered as an estimate of magnitude when only VEI is reported.
