9 Real-time Meteohydropluviometric Monitoring Network of the Campania Region Functional Decentralized Centre Current stations and sensors (september 2011) 192 real-time monitoring stations equipped with: 178 pluviometers 63 hd hydrometers 99 air thermometers 34 soil thermometers 45 hygrometers (air moisture content) 36 barometers (atmospheric pressure) 36 anemometers (wind speed and direction) 35 radiometers (total radiant flux) 3 snow gauges 5 freatimeters 2 soil hygrometers 3 ocean current meters

10 Real-time Meteohydropluviometric Monitoring Network of the Campania Region Functional Decentralized Centre Peripheric stations with electronic sensors, multitasking processors, front-end and its peripherals, solar panel, radio device with a transmitting antenna Solar panel Transmitting antenna Data are automatically ti acquired by sensors periodically, with different time frequency for each sensor. CPU unit buffered memory I.e., data from pluviometric sensors are registered every minute and submitted to a preliminary analysis for detection of errors and pre-validation Network controller radio battery

11 Real-time Meteohydropluviometric Monitoring Network of the Campania Region Functional Decentralized Centre Real-time data are transmitted every 10 minutes to the Elaboration Data Centre of Naples through repeaters by trophosperic radio link.

12 Real-time Meteohydropluviometric Monitoring Network of the Campania Region Functional Decentralized Centre SERVER SQL DataBase Data acquired from frontend system are elaborated, managed and spred by the informatics systems for the support of civil protection authorities in the real-time warning alert system for hydrogeological and hydraulic risk.

13 Regione Campania and natural risks Mission and Strategic Plan Development and implementation of forecasting, monitoring, i scenario models and risk management tools for: Flash floods and landslides; Heavy rainfalls; Earthquakes; Eruptions and volcano-related l phenomena. Sea waves;

14 Put in operation of a Multi-Risk Management Center for Meteohydropluviometric, Volcanic, Seismic risks. (AMRA should work as a center of compentence in this framework). Development of civil protection emergency management plans at regional, district, and municipal levels. Software and hardware supports. Development of communication strategy at a public level for risk understanding, management, and personal mitigation. This is to strenghten a risk management responsibility in communities.

15 Campania seismic extended sources and 10% in 50 yr hazard map

16 Actions: Example of scenario modeling 500 yr return period earthquake scenarios in terms of magnitude and distance from probabilistic disaggregation. Site-by-site most probable earthquakes determining 500 yr accelaration.

17 Municipalities in Near Source regions (directivity effects) N. Municipalities i i On fault surface 68 projection In forward directivity- 74 prone regions Within zones with PGA 107 larger than 0.25g in 500 yr return period map

18 Actions: Seismic early warning has been alredy developed for Campania and it is going to exploited and extended beyond to other risks Structural/nonstructural performance/loss EDP (i.e. Maximum Interstory Drift Ratio) Engineering g Early Warning (1) Seismic network Epicenter IM (e.g. Peak Ground Acceleration PGA) Source-to-site distance Ground motion at the site Signal at the network stations Real-Time Risk Analysis (Performance-Based EW)

19 Engineering Early Warning (2)

20 Programs of Regione Canpamia for reduction of seismic risk (and others) Budget of 75 millions of euros European Funds - to be invested in the period
