COST Action C26

THE VESUVIUS CASE STUDY IN THE FRAMEWORK OF THE EU COST ACTION C26 ACTIVITY

The Vesuvius extreme dangerousness induced the WG4 to introduce the ‘Vesuvius case study’ within its research activities, with particular regard to the effects on the constructions produced by a possible eruption.

The Working Group 4 (“Risk Assessment for Catastrophic Scenarios in Urban Areas”) has been devoted to any natural hazard except earthquake. The focus has been pointed on identification, characterization and modeling of natural disasters,

construction response and possible relevant consequences of combined extreme loadings in the built environment.

Since the beginning, the work seemed too huge without a robust “Ariadne's thread” to follow. Therefore, three directions have been identified for the research:

a) the investigation on each single catastrophic infrequent event; b) the set up of a multi-hazard approach, together with the development of a common methodology for risk assessment;

c) the identification of a pilot study enough general to join several disciplines in a transversal approach.

The investigation on natural catastrophes (except volcanic) has been carried out since the beginning of the Action and continued until its end (Figures 1-5).

1. INVESTIGATION ON NATURAL DISASTERS

2. INVESTIGATION ON VOLCANIC ACTIONS AND VESUVIUS PILOT STUDY

The study on the volcanic phenomena increased strongly during the WG4 activities (Figures 6-20), especially when the Vesuvius was selected as the WG4 pilot study.

Naples meeting – January 23, 2009

Torre del Grecosome buildings (as pilot units) have been selected in order to evaluate in detail the

volcanic actions on constructions:

- an area of Torre del Greco city

center, besides the sea, consisting of

about 100 units made of different

materials (masonry, reinforced

concrete, etc.); also the important

“Palazzo di Città” shall be studied;

- a strip of “sacrifice” buildings (about

20 units), laying on the volcano slope,

which can be heavily damaged or

destroyed by the eruption;

- a strategic facility, as the hospital of

Torre del Greco;

-a cultural heritage building, as the

“Villa delle Ginestre”.

- schools
