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

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

Joris Eggenhuisen has published a fascinating video on Youtube showing a simulation of submarine landslides using the Eurotank Flume at Utrecht University

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.  

A short description and video of an intriguing “mini-tsunami” off the south coast of England on Monday. Reports attribute it to a submarine landslide, but more information is needed to ascertain whether this is really the case.

The NW Rota volcano is located in the Mariana Volcanic Arc, about 100 km north of Guam at a depth of about 520 below sea level. NSF currently funds an scientific expedition to this active volcano; a scientific cruise to this site is currently occurring. The team are running a blog of their experiences and findings – it is here. Yesterday they reported that in the time since their 2009 …

The award for the strangest landslide story of the week goes to this one, from southern Africa. Late last week reports started to emerge of strange tidal patterns around the southern Cape of Africa (Fig. 1). Fig. 1: Google Earth image of the southern Cape of Africa, showing the location of St Helena Bay and Plattenburg Bay. In particular, on 21st August at about 8:45 am (local time) a series …
