- •
High-resolution seismic and RMT data were acquired for studying quick-clay landslides.
- •
Results suggest that both coarse-grained materials and bedrock play key roles.
- •
Quick clays overlay coarse-grained materials that overlap bedrock.
- •
Bedrock shows at places a full bowl-shaped structure implying minimum risk of a landslide.
- •
Two possible scenarios triggering quick-clay landslides are presented.
