Damage assessment and conservation of underground spaces as valuable resources for human activities in Italy and Japan
No full textThis special issue is the main scientific output of the homonymous bilateral project between Italy and Japan “Damage assessment and conservation of underground spaces as valuable resources for human activities in Italy and Japan”. The project was financed
within the agreement regarding the scientific cooperation between the National Research Council of Italy (CNR) and the Japan Society for the Promotion of Science (JSPS) signed on October 23, 2011. The fund supported mutual scientific exchanges between the teams, which were led by Roberta Varriale from the Institute for Studies on the Mediterranean (ISMed), Italy and by Chiaki T. Oguchi from the Graduate School of Science and Engineering of Saitama University, Japan during the period 2018/2019

Sinkhole mechanisms in the Apulian karst
Full text linkSinkholes constitute a significant risk in many karst areas worldwide, and may even threat human safety. Collapse
sinkholes, in particular, that occur catastrophically without showing any premonitory sign may result in severe
economic losses and casualties. In the last years, research on sinkholes and the related detrimental effects
has significantly increased in Italy, in the aftermath of remarkable events in different sectors of the country.
Many events certainly occurred in Apulia region, SE Italy, that is a region almost entirely made of carbonate
rocks, ranging in age from Triassic to Cretaceous limestones and dolostones to Plio-Pleistocene calcarenites
and Quaternary terraced deposits. Due to widespread presence of carbonates, the region is strongly affected by
different types of sinkholes, related to both the natural karst setting and the presence of a high number of karst
caves.
To the sinkholes of natural origin, those related to artificial cavities, that is voids excavated by man underground for
a variety of purposes, have to be added. In the last decades, in particular, anthropogenic sinkholes have repeatedly
affected many Apulian towns, due to the fact that urban expansion often moved toward those areas where in the
past artificial cavities had been excavated. The interaction among present urban areas and infrastructures with the
network of artificial cavities has to be carefully managed, in terms of land planning and safeguard of private and
public properties.
Based upon a well documented sequence of sinkhole events, covering a time span of several decades, an
overview of the main sinkhole mechanisms in Apulia is here presented, aimed at highlighting the related hazard,
and the possible risk to society as well. Some recent examples of sinkholes will be dealt with in detail, covering
the different settings where they develop, from the low coastlines, to inland karst, and eventually to urban areas
Geomorphology of the Canale di Pirro Karst Polje (Apulia, Southern Italy)
No full textCanale di Pirro is one of the most remarkable karst features of the Murge, a typical district of the Apulian karst of southern Italy. It is a 12 km-long polje, with a further and less defined prolongation inland, until reaching an overall length of some 30 km. The floor is filled by thick terra rossa deposits, whilst the slopes are in Cretaceous limestone which represents the bedrock in the area. In the past centuries, this geomorphological feature attracted the attention of several travellers, and was often described as a huge lake, probably because of its characteristic to maintain water at the surface for several days after rainfall, due to the very low permeability of the bottom deposits. As regards caves, two types of natural caves characterize the polje: a prevailing vertical type in the polje floor (difficult to explore because of the infilling deposits that easily clog the access), and sub-horizontal caves in the form of shelters along the slopes. The polje floor develops at two different elevations, separated by an intervening geomorphological saddle: these elevations correspond to two important karst levels in the Murge, as testified by the development of important system of caves in the neighbouring territories. The combination of surface and subsurface geomorphological data provides a first contribution toward a better understanding of the karst history in the area. © 2006 Gebrüder Borntraeger
Landslide mapping techniques and their use in the assessment of the landslide hazard
No full textDifferent types of maps depicting spatial distribution and activity of landslides are discussed in this paper. Analysis of the existing literature on the topic helped to point out advantages and drawbacks of each type of map, and their possible use for the assessment of the landslide hazard. Utility of the landslide maps was also illustrated by means of the results achieved for a real case study in Southern Italy, that highlighted in particular the good amount of information provided by landslide activity maps. © 2001 Elsevier Science Ltd.

Un esempio di idraulica in ambiente carsico: “pozzi” e “pozzelle” del territorio pugliese
No full textIn territori carsici, tipicamente caratterizzati da scarsa presenza di acqua in superficie, la conservazione e raccolta di risorse idriche
ha sempre costituito un rilevante problema, affrontato in epoche passate con una serie di tecniche e soluzioni, al fine di garantirsi una disponibilità, seppur minima, di acqua anche nel corso delle stagioni secche (Parise & Sammarco, 2015). Il carso pugliese, che si sviluppa su gran parte del territorio regionale, coprendo le tre sub-aree carsiche del Gargano, Murge e Salento, mostra numerosi esempi di opere idrauliche realizzate a tale scopo. Il presente contributo illustra, in particolare, le strutture ubicate in zone topograficamente depresse, all’interno di doline di varia origine, in cui talora insistono laghi temporanei: si tratta dei cosiddetti “pozzi” e “pozzelle”, vale a dire cisterne,
di profondità variabile, che si rinvengono in vari settori della Puglia, con la finalità di raccogliere l’acqua piovana, e di poterla utilizzare
a scopi irrigui durante la stagione secca
Instability issues in underground cultural heritage sites
No full textMany sites of cultural heritage present part, or all, of their development underground. In some cases, it is precisely the
underground sector to host the features of greater cultural and historical interest, thus being the most remarkable section
of the site for visitors and scholars. However, entering underground sites, especially after paying a fee for access, requires
these are safe and do not present any element potentially harming workers and visitors. To ascertain such requirements,
prevention studies and researches are needed, aimed at identifying the possible instability features within the cave system
and at their surroundings as well, in order to preliminary evaluate the possibility of failures in the rock mass. This article
summarizes the main activities to carry out at this goal, which should represent the first step for any attempt of opening
underground sites of cultural and historical heritage to the public. After discussing the main characters of cultural heritage
sites with underground development, and their importance in different parts of the world and for many past civilizations,
the article examines the main features observed at Taya Cave, in Japan, in one of the case studies considered within the
framework of the bilateral project JSPS/CNR “Damage assessment and conservation of underground space as valuable
resources for human activities use in Italy and Japan” (2018/2019). Taya Cave, a religious site excavated by Buddhist
monks as a meditation place, consists of several corridors and meditation chambers, distributed over three different levels,
and partly affected by instability signs
