Why submarine landslides?
1) Widespread, large-‐scale margin evolu4on
2) Rapid, m-‐km but affect overall margin shape 3) Geohazard poten4al (process and society) 4) Integrates surface processes and feedbacks
5) Mul4-‐disciplinary -‐ geology, geophysics, geotechnics, fluids…

Key Data/Observa4ons – Slide and Adjacent
1) Morphology and distribu4on 2) In situ pressure, temperature, and strength
3) Tilt and strain data 4) Mul4ple (4d) images or measurements

GeoPRISMS-‐Addressable Ques4ons
What dictates size, runout, and recurrence? -‐ margin shape and evolu4on
What drives failure along different margins? What controls hazard poten4al? Is the failure evolving or stopping? Why? How are different failures recorded in the strata?
