Bridging Legends and Science: Field Evidence of a Large Tsunami that Affected the Kingdom of Tonga in the 15th Century Open
The pre-colonial history (i.e. before the 16th century) of Tonga and West Polynesia still suffers from major gaps despite significant scientific advances in recent years, particularly in the field of archaeology. By the 14th century, the p…

Evidence of Unknown Paleo-Tsunami Events along the Alas Strait, West Sumbawa, Indonesia Open
Indonesia is exposed to earthquakes, volcanic activities, and associated tsunamis. This is particularly the case for Lombok and Sumbawa Islands in West Nusa Tenggara, where evidence of tsunamis is frequently observed in its coastal sedimen…

Barrier Islands Resilience to Extreme Events: Do Earthquake and Tsunami Play a Role? Open
Barrier islands are indicators of coastal resilience. Previous studies have proven that barrier islands are surprisingly resilient to extreme storm events. At present, little is known about barrier systems’ resilience to seismic events tri…

High-resolution late Holocene sedimentary cores record the long history of the city of Cádiz (south-western Spain) Open
Today, coastal cities worldwide are facing major changes resulting from climate change and anthropogenic forcing, which requires adaptation and mitigation strategies to be established. In this context, sedimentological archives in many Med…

Coastal Evolution, Geomorphic Processes and Sedimentary Records in the Anthropocene Open
The question of whether or not we agree with the term Anthropocene becomes inconsequential when examining coastal environments. With few exceptions, anthropogenic encroachment on, and reshaping of, the global coastal zone is evident from s…

Photogrammetry-based Texture Analysis of a Volcaniclastic Outcrop-peel: Low-cost Alternative to TLS and Automation Potentialities using Haar Wavelet and Spatial-Analysis Algorithms Open
Numerous progress has been made in the field of applied photogrammetry in the last decade, including the usage of close-range photogrammetry as a mean of conservation and record of outcrops. In the present contribution, we use the SfM-MVS …

ORRION: A specific information sharing tool to (re)build a “flood risk culture” in the Rhine Graben (France - Germany) Open
\nWhen is led a prevention initiative concerning flood risk, the recall of old events allows just as much to act as pedagogy to legitimize the initiative. So as it is written in the information leaflet on the “Plan de Prévention des Risque…

Preliminary Report of the AMS analysis of tsunami deposits in Tohoku -- Japan -- 18th to the 21st Century Open
Sedimentary records of tsunamis are a precious tool to assess the occurrence of past events, as attested by an abundant literature, which has seen a particular 'boom' in the aftermath of the 2004 Indian Ocean tsunami and the 2011 Tohoku ts…

Rockfall at Fox Glacier: a Hazard Analysis using Structure from Motion and Spatial Modelling Open
As glaciers retreat, downwasting of the ice increases the instability of surrounding rock slopes. In addition, ice thinning can lead to surface morphology changes that can result in a progressively concave transverse profile. This short-te…
