During July 2014 members of the Geology and Geophysics group took part in a major National Oceanography Centre research cruise on board the RV Pelagia. The focus of the cruise, led by Dr Pete Talling, was to investigate the tsunami risk to the coastal areas of the Nordic Sea. The PhD students involved on this… Read More Research cruise investigates large submarine landslides around the Nordic Seas
The question whether each megathrust earthquake necessarily and instantaneously triggers submarine mass-movement has been intensively discussed in the wake of the giant earthquakes that occurred over the last decade. Whereas the 2011 Tohoku-Oki earthquake (Japan) caused failure of parts of the lowermost continental slope, no similar evidence was found after the 2010 Maule earthquake (Central… Read More Megathrust earthquakes and submarine landslides
Are large submarine landslides temporally random or do uncertainties in available age constraints make it impossible to tell? by PhD student Ed Pope Large submarine landslides can potentially generate very destructive tsunamis and damage expensive seafloor infrastructure. Understanding their frequency and triggers is therefore important especially if it is likely to change significantly due to… Read More Are large submarine landslides temporally random or do uncertainties in available age constraints make it impossible to tell?
The results of a recent study which analyses the timing of large submarine landslides have been published in the Journal of Geology. Submarine landslides can be far larger than those on land, and are one of the mostimportant processes for moving sediment across our planet. Landslides that are fast enough to disintegrate can generate potentially very… Read More Do Large Submarine Landslides Occur Randomly?
