The set up of the “UNO” project relational database for Stromboli volcano

<p>Active volcanoes are complex, poorly predictable systems that can pose a threat to humans and their infrastructures. <span>As such</span>, it is important to improve as much as possible the understanding of their behavior. The Stromboli volcano, in Italy, is one of the most active volcanoes in the world, and its almost persistent activity is documented since <span>centuri</span>es. <span>The</span> persistent background activity is sometimes interrupted by much more energetic, dangerous episodes. The <span>Istituto Nazionale di Geofisica e Vulcanologia</span> (Italy) <span>set up</span> the interdisciplinary &#8220;<span>UNO</span>&#8221; project, <span>aimed to</span> <span>understand </span><span>when</span> the Stromboli volcano is about to <span>switch from the ordinary to the</span> extraordinary activity. The UNO project <span>includes</span> an outstanding variety of research activities, such as sampling in the field, the modeling of Stromboli topography from ALS technique and satellite data, the 3D numerical simulations of ballistic trajectories, <span>or</span> the set up of an ultrasonic microphones system. Key to the success of the project <span>is</span> the collection of integrated high spatial and temporal resolution data and their joint analyses in a shared relational database. We <span>present</span> here the simplified <span>logical model</span> of <span>such</span> database, focusing on the identification of entities and their relationships.</p>
