Note that instantaneous breaks occurred out to a distance of approxi- mately 100 nautical miles from the epicenter. Positions of Lamont cores are indicated (1 to 7,V2-6 to V2-9). The contours are not well established because of the absence of recent accurate surveys. (b) Indicating the relation of time of cable breaks to distance from epicenter in nautical miles. Note the line which gives the best fit for a velocity curve. This indicates a uniform velocity of 15 Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hill, M.
