Abstract
This PhD thesis is developed within the framework of Earthquake Early Warning (EEW), a research topic that investigates the feasibility of issuing rapid alerts to mitigate the impact of earthquake striking target sites. The work addresses various aspects of EEW, focusing on the analysis of early P-wave signals and the development of on-site algorithms for earthquake intensity estimation. The main motivation is to improve the timeliness and accuracy of alerts using data from individual stations and short time windows. The original contribution of this research is the development of an on-site EEW software package, tested on datasets from various tectonic environments, including the Campi Flegrei area. Moreover, the analysis of early P-wave displacement growth led to the discovery of a global scaling relationship between the P-wave growth rate and the final earthquake magnitude, offering new opportunities for rapid magnitude estimation. These findings also have implications for earthquake nucleation studies, suggesting that the early portion of the P-wave signals could provide crucial information on the nucleation stage and non- radiative processes preceding dynamic rupture propagation.
