Query: Magnitude clustering and dynamical scaling in trigger models for
  earthquake forecasting   One of the main interests in seismology is the formulation of models able to
describe the clustering in time occurrence of earthquakes. Analysis of the
Southern California Catalog shows magnitude clustering in correspondence to
temporal clustering. Here we propose a dynamical scaling hypothesis in which
time is rescaled in terms of magnitude. This hypothesis is introduced in the
context of a generalized trigger model and gives account for clustering in time
and magnitude for earthquake occurrence. The model is able to generate a
synthetic catalog reproducing magnitude and inter-even time distribution of
thirty years California seismicity.
