The nomogram developed for cost–benefit analysis of Operational Earthquake Forecasting actions. An isopleth (red dotted line) is shown for an example application for a threshold PGA of 0.05 g (left-most axis), a daily probability of an earthquake of magnitude ≥ 4 of 4%, a week-long (7 days) OEF action and a L/C ratio of 1000 leading to R = 3.5 (right-most axis).

It was drawn using a type 3 nomogram and the software Pynomo. See open-access article by Douglas and Azarbakht (2020) for more details.
