Chiarle M., Bondesan A., Carturan L., Scotti R., Annual glaciological survey of Italian glaciers (2023). (IT ISSN 0391-9838, 2024). Results of the 2023 annual glaciological survey conducted on Italian glaciers are here presented. About two-hundred volunteers, assisted by numerous collaborators, operated last year in the three Alpine sectors (Piemonte - Valle d’Aosta, Lombardy and Triveneto) and in the Apennines (Calderone Glacier, Gran Sasso Group) observing two hundred and nine glaciers. One hundred and thirty glaciers were observed in the Piemonte - Valle d’Aosta sector while frontal variation was measured at the snout of fifty-nine glaciers. Twenty-nine and fifty glaciers were visited in the Lombardy Sector and in the Triveneto Sector, respectively (twenty-two and forty-three of which were measured, respectively). Mass balance measurements were conducted on nineteen Italian glaciers during the 2022-2023 hydrological year: four glaciers in the Western Alps (Piemonte - Valle d’Aosta sector), fourteen in the Eastern Alps (three in the Lombardy Sector, the other glaciers in the Triveneto Sector) and one in the Central Apennines

Annual glaciological survey of Italian glaciers (2018)
Annual glaciological survey of Italian glaciers is here summarized.
More than 200 volunteers operated in the three
Alpine sectors (Piemonte - Val d’Aosta, Lombardia and Tre
Venezie) and in the Apennines (Calderone Glacier, Gran
Sasso Group). Data on the frontal variations measured during
the 2018 glaciological survey are reported: 111 glaciers
were visited in the Piemonte - Val d’Aosta Sector (60 were
measured), 23 in the Lombardy Sector (19 measured), 61
in the Tre Venezie Sector (50 measured) and 1 in the Apennines.
Section on mass balance measurements provides
data for 20 Italian glaciers monitored during the 2017-2018
hydrological year
A method to reveal climatic variables triggering slope failures at high elevation
The air temperature in the Alps has increased at a rate more than twice the global average in the last century, and a significant increase in the number of slope failures has also been documented, in particular in glacial and periglacial areas. Thus, the relationship between climatological forcing and processes of instability at high elevation is worth analyzing. We provide a simple, statistically based method aimed at identifying a relationship between climate factors and the triggering of geohazards. Our main idea is to compare the meteorological conditions at the time when the instability occurred with the typical conditions in the same place. Carrying out a straightforward analysis based on the use of the empirical distribution function, we are able to determine whether any of the meteorological variables had nonstandard values in the lead-up to the slope failure event, and thus to identify the variables that are likely to have acted as triggering factors for the slope failure. The method has been tested on five events in the glacial and periglacial areas of the Piedmont Alps (Northwestern Italy) occurring between 1989 and 2008. Out of these five case studies, our research shows that four can be attributed to climatic anomalies (rise of temperature and/or heavy precipitation). The results of this study may contribute to developing knowledge about the relationships between climatic variables and slope failures at high elevations, providing interesting insights into the expected impact of ongoing global warming on geohazards.

Annual glaciological survey of Italian glaciers (2022)
Results of the annual glaciological survey (2022) conducted on Italian glaciers are here presented. About 250 volunteers operated last year in the three Alpine sectors (Piemonte - Valle d’Aosta, Lombardy and Triveneto) and in the Apennines (Calderone Glacier, Gran Sasso Group) observing two hundred and two glaciers. One hundred and eighteen glaciers were observed in the Piemonte - Valle d’Aosta sector while frontal variation was measured at the snout of sixty glaciers. Twenty-seven and fifty-seven glaciers were visited in the Lombardy Sector and in the Triveneto Sector, respectively (twenty-one and forty-three of which were measured, respectively). Mass balance measurements were conducted on seventeen Italian glaciers during the 2021-2022 hydrological year: four glaciers in the Western Alps (Piemonte - Valle d’Aosta sector), twelve in the Eastern Alps (three in the Lombardy Sector, the other glaciers in the Triveneto Sector) and one in the Central Apennines
ANNUAL GLACIOLOGICAL SURVEY OF ITALIAN GLACIERS (2019) CAMPAGNA GLACIOLOGICA ANNUALE DEI GHIACCIAI ITALIANI (2019)
In this paper we present results of the annual glaciological survey (2019) conducted on Italian glaciers. More than 200 volunteers operated in the three Alpine sectors (Piemonte - Valle d'Aosta, Lombardy and Triveneto) and in the Apennines (Calderone Glacier, Gran Sasso Group). Data on the frontal variations measured during the 2019 glaciological survey are reported: 102 glaciers were visited in the Piemonte - Valle d'Aosta sector (54 were measured), 24 in the Lombardy Sector (20 measured), 61 in the Triveneto Sector (54 measured) and 1 in the Apennines. Section on mass balance measurements furnishes data for 21 Italian glaciers monitored during the 2018-2019 hydrological year (4 in the Western Alps, 16 in the Eastern Alps and one in the Central Apennines)
ANNUAL GLACIOLOGICAL SURVEY OF ITALIAN GLACIERS (2021) CAMPAGNA GLACIOLOGICA ANNUALE DEI GHIACCIAI ITALIANI (2021)
The annual glaciological survey (2021) conducted on Italian glaciers is here presented. About 200 volunteers operated last year in the three Alpine sectors (Piemonte - Valle d’Aosta, Lombardy and Triveneto) and in the Apennines (Calderone Glacier, Gran Sasso Group). One hundred and one glaciers were observed in the Piemonte - Valle d’Aosta sector while frontal variation was measured at the snout of fourtynine glaciers. Twenty-seven and fifty-two glaciers were visited in the Lombardy Sector and in the Triveneto Sector, respectively (seventeen and fourtyfour of which were measured, respectively). Data for seventeen Italian glaciers monitored during the 2020-2021 hydrological year are reported in the section on mass balance measurements: four glaciers in the Western Alps (Piemonte - Valle d’Aosta sector), twelve in the Eastern Alps (two in the Lombardy Sector, the other ten glaciers in the Triveneto Sector) and one in the Central Apennines)
