The parameters defining the geological events are, by their very nature, highly uncertain. In addition to these uncertainties, the kinematic approach by itself is only a limiting approximation. The picture that we obtain from the kinematic forword model is therefore a very overconfident repsresentation of reality - an aspect that (hopefully) everyone using Noddy is aware of...
In order to respect the vast nature of these uncertainties, we introduce here an adapted version of the standard geological events defined in Noddy: the definition of a stochastic event:
A stochastic event is geological event in the Noddy history that has an uncertainty associated to it in such a way that, recomputing the geolgoical history will result in a different result each time (note: the definition is borrowed from the notion of stochastic events in probabilistic programming, see for example pymc).
