CT scans of sediment cores (IMAGE)
Caption
CT scan images of turbidites in deep sea sediment cores. On the left, a thin bed of turbidites from a 1906 earthquake. On the right, from an earthquake about 1,500 years ago, the typical "inverted doublet beds" - a doubling or tripling of turbidite thickness. The thick sand up at the top is the San Andreas bed, with the Cascadia bed down below.
