Submarine Landslides and Their Tsunami Hazard
Annual Review of Earth and Planetary Sciences, 2021 Most tsunamis are generated by earthquakes, but in 1998, a seabed slump offshore of northern Papua New Guinea (PNG) generated a tsunami up to 15 m high that killed more than 2,200 people. The event changed our understanding of tsunami mechanisms and was the forerunner to two decades of major tsunamis that included those in Turkey, the Indian Ocean ...

New Insights into the Emplacement Dynamics of Volcanic Island Landslides [PDF]
Oceanography, 2014 Volcanic islands form the highest topographic structures on Earth and are the sites of some of the planet's largest landslides. These landslides can rapidly mobilize hundreds of cubic kilometers of rock and sediment, and potentially generate destructive ...

Introduction to the special issue on submarine geohazard records and potential seafloor instability
Terrestrial, Atmospheric and Oceanic Sciences, 2018 Submarine landslides frequently occur in passive continental margins or active margins (Hampton et al. 1996; Wynn et al. 2000; Mienert et al. 2002; Korup et al. 2007; Twichell et al. 2009; Cukur et al. 2016).

Numerical analysis for impact of submarine landslides on pipelines
Yantu gongcheng xuebao, 2019 Submarine pipelines, as important transporting channels of undersea crude oil and natural gas in marine engineering, are usually in the condition of complex marine geological environment and often damaged by the impact of the submarine landslides.

Impact‐Induced Seafloor Deformation From Submarine Landslides: Diagnostic of Slide Velocity?
Geophysical Research Letters, 2023 Submarine landslides shape continental margins, transfer massive amounts of sediment downslope, and can generate deadly and destructive tsunamis. Submarine landslides are common globally, yet constraining hazard potential of future events is limited by a

In situ observation of wave-induced deformation of submarine landslides in tidal channel areas
Frontiers in Earth Science, 2023 Landslides often occur in land slopes, estuaries, fjords, and intertidal zones in the marine environment, while landslides in tidal channels have not been systematically reported. The Zhoushan sea area is dotted with islands and crisscross tidal channels,

How erosive are submarine landslides?
, 2022 Submarine landslides (slides) are ubiquitous on continental margins. They can pose a major hazard by triggering tsunami and damaging essential submarine infrastructure. Slide volume, which is a key parameter in hazard assessment, can change after initiation through substrate and/or water entrainment. However, the erosive capacity of slides is uncertain.

International Journal of Distributed Sensor Networks, 2018 Offshore pipelines are exposed to potential submarine landslides. It is difficult to measure the impact forces exerted on a pipeline induced by submarine landslides because the upper seabed is very soft and an impact angle exists in practice.

Submarine landslides, relationship with BSRs in the Dongsha area of South China Sea
Petroleum Research, 2016 : Gas hydrate samples were first obtained in the Dongsha area, South China Sea (GMGS2) in 2013. High-resolution 3D seismic data in the area show various small landslide bodies developed as huge mass transport deposits. These bodies are divided into seven

Analytical and numerical studies for wave generated by submarine landslide
Alexandria Engineering Journal, 2022 In this research, we investigate how submarine landslides are able to produce extremely damaging tsunami waves and estimate the maximum height of the waves in question using a mathematical model.
