Marco Pagani
About the speaker: 

Marco Pagani, currently serves as a member of the Executive Committee and coordinator of hazard activities at the Global Earthquake Model (GEM). He has over 10 years of experience in Probabilistic Seismic Hazard Analysis (PSHA), seismic input building, seismic microzonation and exploratory data analysis. Dr. Pagani has been involved in a number of Italian and international research projects dealing with seismic hazard analysis as well as consultancy projects for seismic hazard assessment of critical facilities in Italy and abroad, such as, for example the post-event microzonation projects in the Umbria and Marche regions struck by the 1997 earthquake sequence. As part of his current duties, he’s engaged in a number of international PSHA projects in different parts of the World. Dr. Pagani received a Masters degree in Geological Sciences and a PhD degree in Earth Sciences from the Università degli Studi di Milano. Before joining the GEM Secretariat in Pavia (Italy), he worked in two Research Institutes of the Italian National Research Council, at the Centre d'études techniques de l'Équipement in Nice (France) and at the Swiss Seismological Service of the Swiss Federal Institute of Technology (SED-ETH). Currently his major research interests are the creation of PSHA Input Models combining different information (e.g. seismicity, tectonics and geodesy), the development of advanced PSHA calculation methodologies and their incorporation into the OpenQuake-engine (the hazard and risk calculation engine developed by the Global Earthquake Model). Dr. Pagani is currently serving as a reviewer for a number of international scientific journals and as a convener for a different international scientific conferences. During his academic career he produced a number of publications appearing in international peer reviewed journals and books.

About the event: 

In this update, we provide a summary of activities performed by GEM in the recent past and we illustrate the plans until the end of 2018 when GEM’s second implementation phase will terminate. 

On the hazards side, we describe the tools currently available for building hazard models and for computing seismic hazard and we outline the current status of GEM’s global mosaic of hazard models i.e., the compilation of hazard models that by the end of 2018 will achieve global coverage. The mosaic aims to provide the best open and publicly accessible science for the different areas of the world to increase shared knowledge, hazard awareness and to promote collaboration. It is indeed the combination of several models with a regional coverage (e.g. the EMME model for the Middle East, the SHARE model for Europe, the CCARA model for the Caribbean and Central America) and national models (e.g. Australia, Canada, Japan, New Zealand, Taiwan, United States) all described using the file format and the conceptual data model used to describe hazard input models for the Openquake engine, the open-source hazard and risk calculation engine developed by GEM.

Similar to hazards, through a series of examples, we will describe the main tools and datasets currently under development within the GEM physical risk component. Examples of exposure databases and risk analyses will focus on the results of projects recently completed in South America and the United States.
