A simple stochastic attrition model of termination of small LCR events. LCR events grow by recruitment of neighboring couplons and shrink by extinction of the individual sparks. (A) Average total number of couplons recruited during the life of an LCR event, as a function of the ratio of the spark recruitment to extinction rates. (B) The probability distribution of LCR sizes at different birth/death ratios, with the curves labeled by the mean size from A. For modest average sizes, the distribution approaches a critical power law, suggesting that very large LCR events should be relatively frequent if stochastic attrition were the only mechanism causing LCR termination.
