New article on regional early warning for slushflows

News received from
Monica Sund (NVE, Norway)

A new article entitled “A regional early warning for slushflow hazard” was recently published in the Natural Hazards and Earth System Sciences Journal.

Slushflows are rapid mass movements of water-saturated snow. They release in gently sloping locations (<30°) and are hence not restricted to steep slopes. Slushflows are observed worldwide in areas with seasonal snow cover and pose a significant natural hazard in Norway. Hazard prediction and early warning are therefore crucial to prevent casualties and damage to infrastructure.

A regional early warning for slushflow hazard was established in Norway in 2013–2014 as the first of its kind in the world. It has been operational since then. Four main variables are central in the methodology used: ground conditions, snow properties, air temperature, and water supply to snow. Gridded forecasting model simulations in the decision-making tool Varsom Xgeo, real-time data from automatic stations, and field observations from the field are assessed. Based on data from historical slushflows, a water supply–snow depth by snow type ratio has been developed as an assessment tool. This approach can be implemented in other areas with slushflow hazard where the necessary input data are available.

New article on LEWS and new special issue on landslide research

NEWS received from
Davide Tiranti (Regional Agency for Environmental
Protection of Piemonte, Italy)

A new article entitled “Climate Change Impacts on Shallow Landslide Events and on the Performance of the Regional Shallow Landslide Early Warning System of Piemonte (Northwestern Italy)” was recently published in the GeoHazards journal.

Shallow landslides are responsible for more than 50% of causalities due to landslides in northwestern Italy in the last century. The aim of the research study presented here is focused on understanding if and how climate change influences the occurrence and behavior of this landslide type. A total of 120 widespread shallow landslide events have been analyzed from 1960 to 2019, taking into account the spatial and time distribution in association with related rainfall historical data elaborated by the Optimal Interpolation (OI) model. Results underline that shallow landslide events’ number (aggregated per five-year intervals) is characterized by a weak trend consisting of a slight increase in the Alps and a more pronounced decrease in the hilly and Apennines environments. In addition, the trend of the annual accumulated rainfall average shows a weak drop in the winter season of about 9 mm in ten years. Moreover, the rainy days have generally decreased over the hills and Apennines, while in the Alps, only in the summer season, with a decreasing rate of about 1.5 days every ten years. The rainfall trends are in accordance with those of shallow landslide events, pointing out the close and direct dependence of the shallow landslide events on the rainfall regime variations. The results obtained were also used to validate the robustness of the performance of the Regional Shallow Landslide Early Warning System adopted in Piemonte over the investigated period, confirming the effectiveness of the trigger thresholds used for the entire historical series and for different geographical areas.

Seminar: Insights from the Brienz/Brinzauls landslide (Switzerland)

Seminar by Simon Löw (ETH Zurich) and Andreas Huwiler (Canton of Grisons)

A seminar by Simon Löw (ETH Zurich) and Andreas Huwiler (Canton of Grisons), experts of the crisis management team, will be held online on Thursday, 18 January, 2024, 3:30 to 4:30 pm CET

The massive landslide above Brienz/Brinzauls (Eastern Switzerland) was one of the most highly regarded events in the Alps in 2023. An entire village had to be evacuated and there was great uncertainty as to how far the released mass would run out. In this LandAware seminar, two experts from the operational crisis management will tell us how they experienced the situation before and during the event and what lessons they learned from it.

Simon Löw (ETH Zurich) will explain the hazard scenarios, the expected and observed long-term displacement evolution, the early warning criteria and evacuation phases, and finally the collapse processes.

Andreas Huwyler (Canton of Grisons) will answer questions regarding the communication with the local people who were evacuated one month before the event and with the media.

There will also be time for questions and discussion.

Welcome to save the date and spread the word.

Ethical Science, Equitable and Inclusive Communities

Martha Navarro Collado Memorial Discussions

NEWS received from
Graziella Devoli (NVE, Norway)

Scientists should have an obligation to make their work useful to society. To fulfill this they need to be engaged with society, including people in their science, right from the concept stages – to the final results, and to ensure that their work comes back into the communities impacted by their work.

UNESCO International Geosciences Projects 692 ‘Geoheritage for Resilience’ (www.geopoderes.com) and partners are initiating a discussion on this to cover three important aspects of scientists in society. One, the relationship between scientists from the global north and those from the global south (the latter have the money but are far removed from their impacted communities, the latter are closer but have less). Two, the relationship between local scientists and their local communities, and how to best respect the needs of both, and integrate them. Three, is it possible to draft a charter to set out the behavior that communities and southern scientists could expect northern scientists to uphold? This latter follows initiatives for ethical Science, like the Research Fairness Initiative (RFI).

These topics will be discussed in person at a session at the Cities on Volcanoes Conference, in Antigua Guatemala (11 – 17 February 2024).

Preparatory discussion will be held, starting on the 28th November 4PM CET (Spanish Language session), with an on-line discussion. Or on 29th November 7 AM CET (English Language Session).

Please join us by registering at https://tinyurl.com/yqwchyq9 (Spanish Language session) or by registering at  https://tinyurl.com/mw7pkc (English Language Session) or both!

This session is a Memorial for Martha Navarro Collado, who died in 24th December 2022, and whose life’s work was an embodiment of how support at risk communities, equitable science in Nicaragua. Martha’s life is also an example of the struggle of a woman scientist from a southern (in development) country. She never hesitated to speak her mind forcibly and was very much our conscience in fair engagement across the north – south divide and between scientists and communities.
