摘要：

In this paper, the stochastic Camassa-Holm equation with pure jump noise in the Marcus form is considered.

Firstly, the equation is derived by the stochastic variation method. Then, wave-breaking is shown to occur in expectation.

Furthermore, the global existence is obtained under suitable initial conditions.

Finally, a moderate deviation principle is proved by the regularized equation, the weak convergence method and an exponential equivalence of the probability measures.
