COBAS: Constraining OBservations into Seismic hazard

The project is the 3rd S2 Project funded in the frame of DPC-INGV Agreements. It concerns the mid-long term Seismic Hazard Assessment in Italy, focussing in betterment that can be reached in one-year project on two priority areas. 

The project aims at developing a post-processing chain of seismic hazard assessment (SHA) able to:

  • combine the expected shakings at bedrock with site-specific information gathered at the regional scale
  • convert different kinds of observations (instrumental and not) into proxies of expected shakings and viceversa
  • validate the hazard maps with observations, in order to detect areas of potential underestimation of the forecasted shakings
  • compare and rank different hazard models, according to shared and well-established validation rules, in order to select the best “local” model
  • increase the knowledge about how-to-handle seismic hazard estimate in two peculiar cases, one due to site conditions (liquefactions), and the other to special plants (natural gas storages).

The SPRINT Research Unit plans to compare the damage predictions based on seismic hazard maps with the observed seismic damages. In particular, photos and videos of the seismic damages caused by the earthquakes in Emilia (Italy, 2012) will be acquired and analyzed. These data will be used in order to evaluate the relationship between seismic action and damage, both after the main shock and after the aftershocks. This will allow to to establish the effects of the damage accumulation (caused by main shock and aftershocks) on the macro-seismic intensity.
