I would like to know the difference between mass eruption rate and mass discharge rate. I found only the formula of the column height in Wilson 1978 in which appears the MER, can anyone give me other formulas or references?
1) Lipman, P.W. and Banks, N.G. 1987. Aa flow dynamics, Mauna Loa 1984. US Geol Surv Prof. Paper 1350, 1527-1567.
(effusion rate for instantaneous values; discharge rate for values averaged over a day; mean effusion rate for value averaged over a specific time period, and eruption rate for values averaged over the whole eruption.)
2) Harris, A.J.L., Dehn, J. and Calvari, S. 2007. Lava effusion rate definition and measurement: a review. Bull Volcanol. 70, 1-22.
You can find it online at: http://www.geo.mtu.edu/~raman/papers2/HarrisERateBV07.pdf
Thanks Thomas, I can't find the first one but the second seems very interesting...I read it hoping to find an answer! Sorry, but u can tell me the difference between MER and MDR in two words, if exists? Thannk u very much
