An Empirical Formula to Classify the Quality of Earthquake Locations

Providing a quantitative estimate of earthquake location quality is not a simple task. Traditional methods, used in literature, are not exhaustive and depend on a subjective point of view, because they consist of empirical choice of quality thresholds of different estimators of location uncertainty. However, we notice that these estimators are correlated with one another, implying the need to combine them to obtain a numerical and impartial...
