WG5 meeting with a webinar on “Using Big Data for Postfire Debris Flow Situational Awareness”

News received from
Ben Mirus (USGS, USA) and Manfred Stähli (WSL, Switzerland)

On Thursday, 9 January, 2025, 3:00 – 4:00 pm CET, within the next WG5 meeting, Francis Rengers from the U.S. Geological Survey, St. Golden, will present his work on “Using Big Data for Postfire Debris Flow Situational Awareness”

Teaser: In semi-arid regions of the United States rainfall intensity thresholds are used to estimate when postfire debris flows may occur. Prior research has shown that postfire debris flows are highly correlated with short-duration rainfall intensity, and that short duration rainfall thresholds (e.g., 15-minute rainfall intensity) can be estimated based on wildfire and terrain attributes. Consequently, it is possible to determine possible debris flow activity in recent burn areas in the western U.S.A. by tracking rainfall rates using publicly available rainfall data. We have developed a software (FlowAlert) and an accompanying map dashboard that monitors when and where rain gages near burn areas cross rainfall intensity thresholds. The software runs continuously on a Linux server, processing more than 2500 rain gages every two hours.

In addition to this presentation (with Q&A) the WG meeting will include the following items:

  1. Pop-ups from the working group members (be prepared to contribute with your info to the group!)
  2. Info about recent and upcoming LandAware events and activities
  3. Outlook WG5

New landslide session at EGU25: NH3.16

NEWS received from
Lisa Luna (USGS, USA)

Dear colleagues, 
we’re introducing a NEW landslides session at EGU25: NH3.16 Linking weather-related landslide activity with hydro-meteorological drivers.  Join us to explore how hydro-meteorological drivers at scales from soil pores to weather systems affect landslide activity and to discuss how we can leverage this knowledge to improve landslide situational awareness and early warning.  We seek a wide range of perspectives from geomorphology, hydrology, meteorology, remote sensing, data science and beyond.  Please spread the word and keep our session in mind as you prepare your EGU contributions.

We look forward to learning about your research in Vienna!
Best wishes from the organizers, 
Lisa Luna, Corey Froese, Luca Piciullo, Yaser Peiro, Luca Ciabatta

Session description

NH3.16 Linking weather-related landslide activity with hydro-meteorological drivers

The growing availability of multi-temporal landslide inventories, for example from multi-epoch LiDAR, InSAR, and monitoring, has precipitated a shift from static landslide susceptibility evaluations to a better understanding of both spatial and temporal variations in landslide activity. In parallel, the development of regional to global hydroclimatic models, re-analysis products, next generation remote sensing products, and compilations of in-situ observations (such as ERA5, SMAP-L4, and GSDR) is allowing researchers to obtain a broader understanding of the hydro-meteorological conditions that affect landslide activity: for example soil moisture, snow melt, precipitation, and meso and synoptic scale weather systems. Currently, researchers and practitioners are exploring how linkages between historical landslide activity and hydro-meteorological drivers can be integrated to improve data driven models for landslide situational awareness and early warning systems. This session seeks to bring together a wide range of perspectives from geomorphology, hydrology, meteorology, remote sensing, data science and beyond to share experiences and to spur future research advances and operational application development. 

Subtopics may include:
• Constructing multi-temporal landslide activity data sets utilizing remote sensing data and/or point source terrestrial data
• Linking regional landslide activity trends and variability to hydro-meteorological, geological, morphological, or other conditions.
• Evaluating the suitability of different hydroclimatic models, re-analysis datasets, remote sensing products, and in-situ observations to different landslide and terrain types or research objectives
• Approaches to quantifying linkages between hydro-meteorological drivers and landslide activity
• Development and testing of new algorithms and infrastructure, including machine and deep learning approaches, to support weather-related landslide situational awareness and warning

WG5 meeting: Soil moisture-based thresholds for the assessment of landslide hazard

LandAware WG5 meeting 20 September 2024, 3 p.m. CEST

Luca Ciabatta from the Research Institute of Geo-Hydrological Protection (IRPI) of the National Research Council (CNR), Perugia, will present his recent work on

Soil moisture-based thresholds for the assessment of landslide hazard.

Summary: The Civil Protection Service of Umbria Region, central Italy, developed a landslide early warning system based on soil moisture conditions and rainfall over the regional territory. By identifying the degree of saturation before and after the rainfall event (obtained through a hydrological model), it has been observed that most of the activations occurred when the soil reached saturation. In this way, an alert can be issued when the amount of rainfall needed by the soil to reach saturation is observed. The proposed method is able to identify correctly most of the proposed events with a very limited amount of false alarms.

Dear colleagues (and apologies for any cross-posting),

We encourage you to submit an abstract to the technical session NH030: “Landslide Life Cycle: From Hazard Analysis to Risk Assessment” for the upcoming AGU Fall Meeting taking place 9-12 December 2024. This session has been running several years in a row and is the only broad session focusing specifically on landslides within the Natural Hazards section. We seek contributions that span the landslide life cycle, from understanding landslide hazards to communicating landslide science to reduce risk.

We have two invited speakers this year with unique and contrasting careers and perspectives on landslide hazards:

Professor Roy Sidle, University of Central Asia

and

Dr. Shelby Ahrendt, U.S. Geological Survey

This year’s meeting will be held both in-person in Washington, D.C., USA for those able to attend, and online with options for interactive participation.  Please share this message with anyone that you might know that would be interested in submitting to this session.  Session information follows, please note abstracts are due by 31 July 2024 at 23:59 Eastern U.S. Daylight Time (EDT).

NH030: “Landslide Life Cycle: From Hazard Analysis to Risk Assessment”

Landslide events have adverse and global consequences for human health and safety, infrastructure, economic activity, and natural resources. These hazards can accompany storms, earthquakes, volcanic eruptions, and wildfires, and may shift with climate and land-use change. Landslides can also cause their own cascading consequences like tsunami or river dams. New technologies and enhanced data analysis approaches have accelerated landslide mapping, monitoring, modeling, and outreach efforts, enabling improved characterization and communication of landslide processes and their societal impacts. This session brings together contributions that span the landslide life cycle, from understanding landslide hazards to communicating landslide science to reduce risk. We welcome a wide range of contributions on topics such as characterizing, mapping, and modeling recent or historical landslide events; susceptibility and risk modeling and communication; studies of individual hillslopes or regional scale efforts; rock and soil characterization; quantifying seismic, hydroclimatic, or other triggering mechanisms; and ground-based and remote monitoring.

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
