90 years after the 1929 Grand Banks earthquake: the hazards of submarine landslides on the western North Atlantic passive margin
On the 90th anniversary of the 1929 Grand Banks earthquake and tsunami, a new study suggests that tsunamigenic submarine landslides may be more common than we thought
In a new paper, Zhu et al. (2019) report the discovery of the giant Baiyun–Liwan submarine slide, which covers an area of c.40,000 sq km in the South China Sea
Submarine landslides can creep too: we have just published a paper (Carey et al. 2019) in the journal Geomorphology exploring the mechanisms of movement of the Tuaheni landslide offshore from New Zealand
A new paper in the journal Geology (Urlaub et al. 2018) proposes that the key factor that allows giant submarine landslides maybe the combination of compressible diatom ooze and a capping layer of low permeability clay
In a new paper, Hunt and Jarvis (2017) demonstrate that multiple large submarine landslides have occurred close to the Canary Islands in the last 7 million years.
In New Zealand, two research cruises by NIWA have mapped massive submarine landslides triggered by the Kaikoura earthquakes
Submarine landslides are poorly understood, in part because it is so difficult to capture them in real-time. This makes the following video, recorded at Cabo Sab Lucas, Baja California in Mexico, incredible valuable: Hat tip to Pasi Jokela for highlighting this one.
