Submarine slides and marine geohazards:

Offshore geohazards and seabed mobility

This research stream is focussed on offshore hazards, with particular attention to the mobility of the seabed – whether through large scale geological events, or local scale sediment transport processes. This report is divided into two broad areas. We have extensive activity to report on the subject of seabed mobility, through studies around the O-Tube program (see also the separate report on t...

Addressing Geohazards Through Ocean Drilling

Natural geohazards, such as earthquakes, volcanic eruptions, landslides, and volcanic collapse, are of immediate societal concern. In an oceanic setting (Fig. 1), all are capable of generating tsunami that threaten coastal zones at distances of many thousands of kilometers. This power and its effects were forcefully shown by the giant earthquake (� w 9.2) and tsunami of 26 December 2004 off t...

Grand Challenges in Geohazards and Georisks

Risk Assessment and Management for Offshore Geohazards

The state-of-the-art in understanding offshore geohazards has advanced significantly in the past decade. The advances have been mostly driven by the needs of the offshore petroleum industry. The pace of exploration and field development on the continental slopes and in ultra-deep waters worldwide has increased rapidly during the past decade. Activities are concentrated in areas where the sedime...
