Earthquake Seismology Aldo Zollo
The course illustrates the processes that cause earthquakes and the methodologies used by seismologists to analyze the seismograms, to measure the source parameters and to simulate the earthquake effects at the Earth's surface.
The main concepts and experimental facts related to earthquakes are first reviewed, by introducing the different observation scales of the seismic phenomena: the source size, the extent of the monitoring networks and the frequency/wavelength range of seismic signals.
The point-like approximation of the earthquake source has long been used to characterize the earthquake process. It will be used to introduce the concepts of earthquake location, magnitude, seismic moment and focal mechanisms which derive from this simplifying but effective view of the earthquake phenomenon.
But earthquakes are caused by rupture phenomena developing on extended fault surfaces hidden in the brittle Earth layers. The rupture kinematic and dynamic models and observations will illustrate the modes of nucleation, propagation and arrest of the earthquake rupture. They help seismologists to simulate the seismic wave propagation and to predict the ground shaking produced by destructive events.
Finally, the course will overview the basic elements of real-time seismology. It concerns the automatic processing of the earthquake signals, aimed at the fast event detection and source characterization for early warning purposes.

Aldo Zollo graduated in Physics and did a PhD in Solid Earth Geophysics at the University of Paris VII, France (1991). He has worked as Researcher (1991-1992), Associate Professor (1993-2002) and then Full Professor of Seismology at the University of Naples Federico II.
Since 1993, A. Zollo has taught courses in Earth Physics and Seismology at the Faculty of Sciences at the University of Naples Federico II, where he has been Coordinator of the Doctoral School in Seismic Risk since 2006.
He has headed several national and international research projects and, in addition, was editor of the Journal of Geophysical Research (1993-1996) and Geophysical Research Letters(Solid Earth)(2001-2007).
Member of the INGV Scientific Committee for 11 years (2011-2010), since 2011 ha has been a member of the National Group of Experts for the Evaluation of Research in the field of “Earth Sciences” (GEV04) and Member of the National Commission for Forecasting and Preventing Great Risks (Seismic Risk area).
In 2007 he was awarded the honour of 'Commendatore della Repubblica Italiana' for scientific achievement by the Italian President of the Republic Giorgio Napolitano.
