Mt. Erebus Volcano Eruption Index (K-Scale)

Sizes measured in Pa from the Infrasonic overpressure at station E1S.IS1
*Size estimate based on seismic comparison with known eruption sizes

+ Eruption sizes before Feb. 7, 2006 may be larger than reported due to infrasonic sensor saturation

0-19 = Small Eruption | 20-39 = Medium Eruption | 40-59 = Large Eruption | 60+ = Very Large Eruption
