In case of an earthquake, of magnitude 4 or more, an automatic procedure is immediately activated by DPC to produce data, maps, and information concerning:

– Description of the area (anthropic, physical and administrative aspects; characteristics of buildings and infrastructures; monitoring networks)

– Vulnerability (building stock, schools, hospitals)

– Hazard (seismogenic zones, catalogue, isoseismals, attenuation)

USABILITYPost-earthquake usability evaluation is a quick and temporarily limited assessment, based on expert judgement of specially trained technical teams, on visual screening and on easily collected data, aimed to detect if, during the current seismic crisis, damaged buildings can be used, being reasonably safeguarded the human life.

Building could be used, but it cannot due the high risk caused by external factors (heavy damaged adjacent or facing buildings, possible rock falls, etc.)

F) UNUSABLE FOREXTERNAL RISK

Building can not be used due to high structural, non structural or geotechnical risk for human life. Not necessarily imminent risk of total collapse.

E) UNUSABLE

Building to be re-inspected. Unusable until the new inspection.

D) TEMPORARILY UNUSABLE

Only a part of the building can be safely used C) PARTIALLY USABLE

Building is damaged, but can be used when short term countermeasures are taken

B) USABLE WITH COUNTERMEASURES

Building can be used without measures. Small damage, but negligible risk for human life.

- A partire dall’8 aprile iniziate verifiche di agibilità su scuole di competenza comunale (da nido a medie) e provinciale (superiori) site a L’Aquila ed in provincia

- A l’Aquila visitate 48 scuole di competenza comunale (su un totale di 57) e 7 scuole di competenza provinciale (su un totale di 10); in totale, 106 corpi di fabbrica

- In termini di studenti le scuole comunali visitate ospitano circa 5,000 studenti (su circa 7,000 totali) e quelle provinciali circa 3,500 studenti (su circa 5,000 totali)

- In provincia, sopralluoghi in 64 comuni, visitate 224 scuole per un totale di 309 corpi di fabbrica

Verifiche di agibilità: scuole di L’AquilaScuole comunali-18 agibili (A) (845 studenti)- 14 agibili con provvedimenti lievi (B) (2,186 studenti)- 16 inagibili (C o E) (circa 2,000 studenti)

Scuole provinciali- 3 corpi agibili (A) (circa 1,000 studenti)- 4 corpi agibili con provvedimenti lievi (B) (1,500 studenti)- rimanenti corpi visitati inagibili (C o E) (circa 1,000 studenti)

Verifiche di agibilità: provincia di L’Aquila- 243 corpi agibili (A) - 46 corpi agibili con provvedimenti lievi (B) - 20 inagibili (C o E)

COMPETENCE CENTRES OF DPC

• INGV(Seismic surveillance, Emergency technical support, Seismological research projects)

• RELUIS(Emergency technical support, Earthquake engineering research projects)

• EUCENTRE(Emergency technical support, Earthquake engineering research projects)

In the past three years, PC research funds amounted to about 10 M€ / year

….. CONCLUSION (4)

• Monitor soil and structures with mobile instrumentation, to evaluate aftershock effects,

• survey earthquake effects on natural (landslides, liquefactions, soil fractures, etc.) and built environment (macroseismic survey, damage assessment, etc.).

In the future, a structured involvement of CTS’s is envisaged even in the emergency phase to:

Also in post-event activities important synergies could be established between research and CP:

EARTHQUAKES REPRESENT FULL SCALE EXPERIMENTS THAT PROVIDE SIGNIFICANT AND

STIMULATING HINTS FOR SCIENTISTS.
