In geomorphology, an event which puts an end to the balance between driving and resisting forces and thus sets the mass moving (T. Erismann and G. Abele 2001). P. Fookes et al. (2005) consider the main predisposing and triggering factors of geomorphological surface processes, including climate and weathering, sedimentology, tectonics, and stratigraphy. Jones and Omoto (2000) Sedimentol. 47, 6 outline the criteria that can be used to identify a seismic triggering agent. See also Moro et al. (2007) Geomorph. 89, 3–4. For an example of atmospheric triggering, see Miniscloux et al. (2001) J. Appl. Climat. 40, 11.
