During the past 400 ka, a broad rollover fold formed in the middle slope area, in association with a major seaward-dipping detachment fault. A catastrophic debris avalanche occurred as the result of oversteepening of the landward flank of the rollover fold. The gravity failure of the slope, previously recognized by SeaBeam mapping, occurred at 13.8 ±2.7 ka and produced a destructive tsunami. This content is PDF only.
