WG5 webinar “Landslide susceptibility and road-network connectivity with Machine Learning”

Recording of the WG5 meeting of 25 June 2024

Topic: Landslide susceptibility and road-network connectivity by means of Machine Learning

Joshua Dimasaka (Cambridge University, Centre for Risk in the Built Environment) presented his work on how landslide susceptibility and the associated road-network connectivity can be calculated with Machine Learning. And he showed a very illustrative application of his methods to the case of Norway.

The recorded presentation is available on our YouTube channel:

Landslide session in MedGU24

NEWS received from
Ugur Öztürk (Universtiy of Potsdam, Germany)

Dear colleagues,

this year, there is an exciting conference in Barcelona—the Mediterranean Geosciences Union (MedGU) annual meeting—between 25 and 28 November. It is the largest meeting dedicated to exchanging ideas on addressing critical societal and environmental challenges in the Mediterranean Region from the geoscience perspective.

Among several engaging sessions, we (Tolga Görüm, Olivier Dewitte, Anika Braun. Ugur Öztürk) suggested one dedicated to the landslide theme (Landslides: Processes, Hazard, Vulnerability, and Risk). Among these broad themes, we want to particularly emphasize landslide prediction and early warning. Hence we invite you to submit an abstract to this special session or any other at MedGU24.

Abstract submission deadline is 30th June 2024

New LEWS article in open discussion

NEWS received from
Ben Mirus (USGS, USA)

We would like to draw your attention to a new NHESS Invited Perspectives, which is now posted online. The paper focuses on lessons learned from our collective experiences with integrating hydrologic information into landslide forecasting models in different parts of the world, as well as ideas for future research needs and opportunities. 

As with all EGUsphere articles, the paper is fully open access and free to read. We hope you will find it interesting and perhaps it can facilitate further discussions within the LandAware community. The preprint is open for discussion through June 24, and we would value your input whether formally or informally.

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 webinar by NASA and Pacific Disaster Center on Landslide Hazard Awareness

The webinar Landslide Hazard Awareness – NASA and Pacific Disaster Center cooperation to support decision-making” is scheduled for April 11, 2024 in the following time slots:

1:00 p.m-2:30 p.m. (EST)
11:00 a.m. 12:30 p.m. (Centro América)
7:00 p.m.-8:30 p.m. (CEST)

To join the webinar use the following link

Key objectives:
Present Research Findings and showcase the partnership between NASA and the Pacific Disaster Center (PDC) in leveraging advanced technologies and data to improve landslide hazard assessment and decision-making processes. Introduce participants to the various tools, platforms, and resources developed through the collaboration between NASA and the PDC, such as landslide risk maps, and decision support tools.

Expected outcomes:
At the end of the webinar, it is expected that participants will have gained a better understanding of the actions and strategies implemented by the organizations involved in the region and that concrete opportunities for future collaboration will have been identified. In addition, it seeks to foster a renewed commitment to risk reduction and resilience in Central America.

Expected audience:
The webinar is open to all LandAware associates in particular those from the LatinAmerica region or working with landslide early warning systems in the region. The webinar is aimed in particular at the network on landslides in Central America made up of experts from official institutions in Central American countries, such as INSIVUMEH of Guatemala, INETER of Nicaragua, SGR of Costa Rica, SINAPROC of Panama, COPECO of Honduras, and MARN of El Salvador.

Next steps – After the webinar:
A monitoring process will be carried out that will include preparing a report with the conclusions and recommendations that emerged during the event. In addition, the possibilities of establishing working groups or joint projects will be explored to advance risk reduction in the region.

EGU24 LandAware get-together in Vienna on Thursday, April 18

As we did in 2022 and 2023, we would like to take advantage of the fact that some LandAware members will be in Vienna at #EGU24 in April… to get together for one evening, to meet and talk in person.

We chose Thursday, April 18, 2024, because that’s the day the session on landslides early warning systems (NH3.7 Towards innovative landslide monitoring, modelling, and early warning systems) is scheduled, thus we are assuming that if you will attend EGU24 , you will most likely be in Vienna on that evening.

The get-together will be an informal dinner with good Austrian beer, self-funded by the participants (unfortunately LandAware doesn’t have any funding to manage), in a restaurant/brewery: Salm Brau. We suggest we meet there at 7:30 PM.

If you are in Vienna on that day, and you like the idea, we ask you to FILL THIS FORM  as we need to know in advance the number of people participating (a reservation is necessary in that place).

Looking forward to seeing you in Vienna!

A new addition to the “LEWS fact sheets” project: Alerta Rio

NEWS received from
Michele Calvello (University of Salerno, Italy)

The “LEWS fact sheets” is an ongoing project of the eLearning Working Group, aiming to highlight, in a single page, the main characteristics of operational landslide early warning systems. Go to the dedicated web page ( to see the fact sheets produced and published so far.

The latest fact sheet produced and uploaded deals with “Alerta Rio” the municipal system operating in Rio de Janeiro (Brazil), which has been operational since 1996. Enjoy learning how it works.

Note: Are you a LEWS manager wanting your system to gain visibility by means of “our” fact sheets? Are you a LandAware member wanting to help us in creating new fact sheets? Do not hesitate to contact Michele Calvello or Anne Felsberg.
