OTHER EXAMPLES OF DECREASING FLOW-FRONT ADVANCE RATES (adapted from Kilburn 1996)
the max. effusion rate was probably ~400 m3 s-1, approx. twice the effective effusion rate average effusion rate for whole eruption was ~115 m3 s-1, approx. 50% of the effective effusion rate EFFECTIVE EFFUSION RATES 1984 flows, ~2900 m vent Flow front positions from Lockwood et al. (1987) Effusion rates from Lipman et al. (1985), Lipman & Banks (1987)
