    THE SPIRAL OF CLIMATE. Civilizations of the Mediterranean and Climate Change in History (2012)
    Bononia University Press
    Details
    Publication Date: 2012-02-03
    Description: The climate has always been subject to changes, and these have often caused trouble and posed unexpected threats. People have had to adapt by finding socially, culturally and economically adequate answers. Based on authoritative scientific and historical studies, this book explores the civilizations that have called the Mediterranean their home during the last 3,000 years, and makes their history accessible to a wide readership. Aided by a group of researchers, the authors aim not only to delineate climatic trends and their social repercussions through the centuries, but also to address the ideas and theories set forth by thinkers since time immemorial. This book gives voice to ancient Greek and Latin philosophers, medieval encyclopedists (Christian and Arab), intellectuals of the modern era and the Enlightenment, and exponents of nineteenth-century positivism. Ancient and recent Mediterranean civilizations alike concerned themselves with weather forecasts, the climate and health, and the relationship between climate and the environment: they have elaborated on these issues and come up with answers since antiquity. Casting light on largely unexplored aspects of history, this journey through time works its way to the present global warming. The new challenge that lies before us is best assessed in a perspective of “historical climate change,” to which the doings of humankind are adding great momentum.

    Lava flow hazard at Nyiragongo volcano, D.R.C. : 1. Model calibration and hazard mapping (2008)
    Springer-Verlag
    Details
    Publication Date: 2017-04-04
    Description: The 2002 eruption of Nyiragongo volcano constitutes the most outstanding case ever of lava flow in a big town. It also represents one of the very rare cases of direct casualties from lava flows, which had high velocities of up to tens of kilometer per hour. As in the 1977 eruption, which is the only other eccentric eruption of the volcano in more than 100 years, lava flows were emitted from several vents along a N–S system of fractures extending for more than 10 km, from which they propagated mostly towards Lake Kivu and Goma, a town of about 500,000 inhabitants. We assessed the lava flow hazard on the entire volcano and in the towns of Goma (D.R.C.) and Gisenyi (Rwanda) through numerical simulations of probable lava flow paths. Lava flow paths are computed based on the steepest descent principle, modified by stochastically perturbing the topography to take into account the capability of lava flows to override topographic obstacles, fill topographic depressions, and spread over the topography. Code calibration and the definition of the expected lava flow length and vent opening probability distributions were done based on the 1977 and 2002 eruptions. The final lava flow hazard map shows that the eastern sector of Goma devastated in 2002 represents the area of highest hazard on the flanks of the volcano. The second highest hazard sector in Goma is the area of propagation of the western lava flow in 2002. The town of Gisenyi is subject to moderate to high hazard due to its proximity to the alignment of fractures active in 1977 and 2002. In a companion paper (Chirico et al., Bull Volcanol, in this issue, 2008) we use numerical simulations to investigate the possibility of reducing lava flow hazard through the construction of protective barriers, and formulate a proposal for the future development of the town of Goma.

    Lava flow hazard at Nyiragongo volcano, D.R.C. : 2. Hazard reduction in urban areas (2008)
    Springer-Verlag
    Details
    Publication Date: 2017-04-04
    Description: Mt. Nyiragongo is one of the most dangerous volcanoes in the world for the risk associated with the propagation of lava flows. In 2002 several vents opened along a huge system of fractures, pouring out lava which reached and destroyed a considerable part of Goma, a town of about 500,000 inhabitants on the shore of Lake Kivu. In a companion paper (Favalli et al. in Bull Volcanol, this issue, 2008) we employed numerical simulations of probable lava flow paths to evaluate the lava flow hazard on the flanks of the volcano, including the neighbouring towns of Goma (DRC) and Gisenyi (Rwanda). In this paper we use numerical simulations to investigate the possibility of significantly reducing the lava flow hazard in the city through the construction of protective barriers. These barriers are added to the DEM of the area as additional morphological elements, and their effect is evaluated by repeating numerical simulations with and without the presence of barriers. A parametric study on barrier location, size, shape and orientation led to the identification of barriers which maximize protection while minimizing their impact. This study shows that the highest hazard area corresponding to eastern Goma, which was largely destroyed by lava flows in 2002, cannot be effectively protected from future lava flows towards Lake Kivu and should be abandoned. On the contrary, the rest of the town can be sheltered from lava flows by means of two barriers that deviate or contain the lava within the East Goma sector. A proposal for the future development of the town is formulated, whereby “new” Goma is completely safe from the arrival of lava flows originating from vents outside its boundaries. The proposal minimizes the risk of further destruction in town due to future lava flows.

    NELLA SPIRALE DEL CLIMA culture e società mediterranee di fronte ai cambiamenti climatici (2010)
    Bononia University Press
    Details
    Publication Date: 2017-04-04
    Description: Il clima è sempre cambiato e i mutamenti hanno causato danni e rischi non previsti, che hanno richiesto nuovi adattamenti e risposte adeguate sul piano sociale, culturale ed economico. Gli autori, coadiuvati da un gruppo di ricercatori, hanno esplorato la storia degli ultimi tre millenni delle civiltà mediterranee, presentando un excursus divulgativo, basato su autorevoli studi scientifici e storici. Lo scopo è di delineare in modo complessivo non solo l’andamento dei mutamenti climatici e le loro ripercussioni sociali, ma anche le idee e le teorie sul clima, dai filosofi dell’antica Grecia, agli scrittori latini, agli enciclopedisti medievali, cristiani e arabi, fino al pensiero di età moderna, all’illuminismo e al positivismo ottocentesco. Le previsioni del tempo, il clima e la salute, il rapporto fra clima e ambiente sono temi presenti in tutte le civiltà mediterranee antiche e recenti: su questi temi le culture hanno sempre elaborato interpretazioni e risposte. Questo “viaggio” nel passato, che mette in luce una storia inedita e in gran parte da esplorare, giunge fino all’attuale riscaldamento globale. Questa nuova sfida è meglio valutabile in una prospettiva di “mutamento climatico storico”, a cui l’azione antropica sta aggiungendo un formidabile acceleratore.
