Summary

Subduction zones host the largest earthquakes and associated tsunamis. Several subduction earthquakes have been preceded by a precursory activity, namely an increase of the seismicity rate before the mainshock.
In this seminar I will discuss examples of how this accelerated seismicity can be associated with other deformation or seismological transient signals at various time and space scales: from localized preseismic slip on the subduction interface before the earthquake, to intriguing long-term and/or large-scale interactions between seismicity and deformation.
