True Volumes of Slope Failure Estimated From a Quaternary Mass‐Transport Deposit in the Northern South China Sea [PDF]

Geophysical Research Letters, 2018
Submarine slope failure can mobilize large amounts of seafloor sediment, as shown in varied offshore locations around the world. Submarine landslide volumes are usually estimated by mapping their tops and bases on seismic data.

Submarine landslide source models consistent with multiple tsunami records of the 2018 Palu tsunami, Sulawesi, Indonesia

Earth, Planets and Space, 2020
Previous studies have suggested submarine landslides as sources of the tsunami that damaged coastal areas of Palu Bay after the 2018 Sulawesi earthquake.

Research on Submarine landslide monitoring and early warning system [PDF]

E3S Web of Conferences, 2021
Monitoring and early warning of submarine landslides could provide instant predictions for landslides, which is to avoid the destructive damage of submarine facilities such as pipelines and optical cable, etc effectively. However, researches on submarine

Reciprocal Green's functions and the quick forecast of submarine landslide tsunamis [PDF]

Natural Hazards and Earth System Sciences, 2020
Although tsunamis generated by submarine mass failure are not as common as those induced by submarine earthquakes, sometimes the generated tsunamis are higher than a seismic tsunami in the area close to the tsunami source, and the forecast is much more ...

Three-Dimensional Modeling of Tsunami Waves Triggered by Submarine Landslides Based on the Smoothed Particle Hydrodynamics Method

Journal of Marine Science and Engineering, 2023
Submarine landslides are a global geohazard that can displace huge volumes of loose submarine sediment, thereby triggering enormous tsunami waves and causing a serious threat to coastal cities.

Analytical and numerical investigation on the energy of free and locked tsunami waves generated by a submarine landslide

The Physics of Fluids, 2023
Submarine landslides are capable of causing locally catastrophic tsunamis. Landslide parameters, particularly those related to the landslide motion, are highly uncertain in a real landslide tsunami event.

A two-layer shallow flow model with two axes of integration, well-balanced discretization and application to submarine avalanches [PDF]

, 2020
We propose a two-layer model with two different axes of integration and a well-balanced finite volume method. The purpose is to study submarine avalanches and generated tsunamis by a depth-averaged model with different averaged directions for the fluid ...

Large-scale submarine landslide drives long-lasting regime shift in slope sediment deposition

Geology, 2023
Submarine landslides and associated mass-transport deposits (MTDs) modify the physiography of continental margins and influence the evolution of submarine sediment routing systems.
