Testing of the seismic gap hypothesis in a model with realistic earthquake statistics

G Petrillo, A Rosso, E Lippiello - Journal of Geophysical …, 2022 - Wiley Online Library
The seismic gap hypothesis states that fault regions where no large earthquake has recently
occurred, are more prone than others to host the next large earthquake. It can lead to the …
