The presence of gas is a widespread phenomenon in marine and coastal soils, often accompanied by complications in engineering application. The characteristics of the gas phase in the pore space are relevant for the assessment of the soil mechanical implications. In granular soils the formation of capillary bridges between the soil particles can inv...

Small amounts of gas occur in almost every sediment in marine or coastal environments. In past studies, a negative influence of gas on the mechanical properties of soil was associated with geohazard occurrence and dike safety in tide affected areas. However, the impact of a homogeneous distribution of gas bubbles in soil on its mechanical propertie...

Submarine landslides can destroy seafloor infrastructures and generate devastating tsunamis. In spite of decades of research into the functioning of submarine landslides there are still numerous open questions, in particular how different phases of sliding influence each other. Here, we re‐analyze Ana Slide—a relatively small (<1 km³) landslide off...

Submarine landslides can entail a substantial hazard for offshore infrastructure as they are capable of triggering tsunamis and may develop into highly mobile turbidity currents capable of breaking seabed cables. Despite considerable research activity, the trigger mechanisms for such landslide events cannot be clearly defined. Recently, marine gas...

The destructive potential of submarine landslides for populated coastal areas and maritime infrastructure has been described many times. However, the geological processes that can trigger such landslide events have not yet been fully established. In order to be able to conclusively assess the trigger potential of these processes, a quantification o...

The development of debris flows and turbidity currents in the course of a submarine slope failure event can cause major damage in offshore infrastructure. Additionally, the tsunamogenic potential of large slope failures at continental margins poses a direct threat to coastal communities. Therefore, the trigger mechanisms of submarine slope failures...

Submarine slope failures pose a direct threat to seafloor installations and coastal communities. Here, we evaluate the influence of free gas on the soil's shear strength and submarine slope failures in areas with gassy soils based on an extensive literature review. We identify two potential destabilization mechanisms: gas bubbles in the pore space...
