25 (adapted from Kilburn 1996) OTHER EXAMPLES OF DECREASING FLOW-FRONT ADVANCE RATES

26 EFFECTIVE EFFUSION RATES Flow front positions from Lockwood et al. (1987) Effusion rates from Lipman et al. (1985), Lipman & Banks (1987) average effusion rate for whole eruption was ~115 m 3 s -1, approx. 50% of the effective effusion rate 1984 flows, ~2900 m vent the max. effusion rate was probably ~400 m 3 s -1, approx. twice the effective effusion rate
