Planned relocation due to landslide-triggered tsunami risk in recently deglaciated areas

Improving Risk Assessment of Subaqueous Landslides and Tsunami Generation by Understanding the Roles of Pore Pressure and Sediment Cohesion

“…When considering tsunami risk, communities along active margins, such as the Cascadian, Alaskan, and Japanese margins, are typically considered to be at higher risk than passive margin communities (Lemke, 1967;Von Huene and Lallemand, 1990;Bardet et al, 2003;Finn, 2003;Yalçıner et al, 2003;Bondevik et al, 2005;Fine et al, 2005;Bernard et al, 2006;Hornbach et al, 2007;Mcadoo et al, 2008;Tappin et al, 2008;Moscardelli et al, 2010b;Garces et al, 2010;Loveless and Meade, 2010;Harbitz et al, 2014a;Scholz et al, 2016;Fujiwara et al, 2017;Strasser et al, 2019;Imai et al, 2019;Goda et al, 2019;Sun and Leslie, 2020;Ikehara et al, 2021;Matti et al, 2023). However, tsunamigenic landslides occur along passive margins, and these failures are generally larger than on active margins and can generate large tsunamis (Kvalstad et al, 2005;Urlaub et al, 2012;Harbitz et al, 2014a;Løvholt et al, 2019;Paris et al, 2019).…”

“…As there is a direct relationship between landslide volume and tsunami height (Murty, 2003), events in either margin types can be devastating (Amir et al, 2013;Goda et al, 2019;Matti et al, 2023). However, efforts to increase community resilience to such events along active and passive margins typically overlook forecasting event likelihood and severity, focusing on https://doi.org/10.5194/egusphere-2024-622 Preprint.…”

Migration in the Context of Climate and Environmental Changes within Central Asia and to the European Union and the Russian Federation

“…However, when relocation occurs in sites where livelihood opportunities similar to those available in sites of origin are not available, relocation can undermine economic opportunities, cultural practices and social connections, leading to secondary migration. Research studies indicate that when international planned relocation guidelines and best practices are not followed, the participation of affected people in decision-making risks to be limited or neglected, in turn overshadowing the need for adequate compensation of those to be relocated (Matti et al, 2023). In the following sections, the two case studies of Tajikistan and Kyrgyzstan underline these aspects as well as the importance of fully including households in relocation design characteristics to unveil its benefits.…”
