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 ...

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.

The first ultra-high resolution Digital Terrain Model of the shallow-water sector around Lipari Island (Aeolian Islands, Italy) [PDF]

, 2015
Very high resolution bathymetric map obtained through multibeam echosounders data are crucial to generate accurate Digital Terrain Models from which the morphological setting of active volcanic areas can be analyzed in detail. Here we show and discuss

Spatiotemporal evolution, mineralogical composition, and transport mechanisms of long-runout landslides in Valles Marineris, Mars [PDF]

, 2020
Long-runout landslides with transport distances of >50 km are ubiquitous in Valles Marineris (VM), yet the transport mechanisms remain poorly understood.

Deep submarine landslide contribution to the 2010 Haiti earthquake tsunami

Natural Hazards and Earth System Sciences, 2020
. The devastating Mw 7.1 Haiti earthquake in 2010 was accompanied by local tsunamis that caused fatalities and damage to coastal infrastructure. Some were triggered by slope failures of river deltas in the close vicinity of the epicenter, while others ...

Large-scale mass wasting in the western Indian Ocean constrains onset of East African rifting

Nature Communications, 2020
The authors describe a huge submarine landslide deposit offshore Tanzania and highlight that large and potentially tsunamigenic landslide events are associated with plateau uplift and continental rifting in East Africa.

Sedimentology, structure and age estimate of five continental slope submarine landslides, eastern Australia [PDF]

, 2016
Sedimentological and accelerator mass spectrometry (AMS) 14C data provide estimates of the structure and age of five submarine landslides (∼0.4–3 km3) present on eastern Australia's continental slope between Noosa Heads and Yamba.

Assessment of Submarine Landslide Volume

, 2023
Abstract Submarine landslides pose major geohazards as they can destroy seafloor infrastructure such as communication cables and cause tsunamis. The volume of material displaced with the landslide is one factor that determines its hazard and is typically estimated using bathymetric and/or seismic datasets.
