What is it about?

We present experimental evidences supporting the hypothesis of correlation between the magnitudes of the events in mother-daughter causal relation. On the basis of these evidences, we propose a new version of the classical time-magnitude ETAS model.

Why is it important?

We propose a very useful new model, that is a new version of the classical time-magnitude ETAS model, in which seismicity is described in a more realistic and intuitive way. Our new model does not complicate the analysis so much and is derived from the experimental evidences obtained for some seismic catalogs, both real and simulated. The new model can be the basis for the study of many aspects of seismicity, like for example the study of the interevent times.

Perspectives

My perspective is the study of many useful aspects of seismicity in a more realistic way. The new model proposed could be fundamental to reobtain results about for example interevent times, quiescence and seismic sequnces' extinction.
