Description: This map shows an area between 30 degrees of latitude north, and 45 degrees of latitude north; and between 65 degrees of longitude west, and 50 degrees of longitude west. The land shown is the southern part of the island of Newfoundland with an arrow showing Burin Peninsula, Prince Edward Island and Nova Scotia. The water represented in blue is the Atlantic Ocean with the location of the Grand Banks. A light blue area shows the extent of a submarine landslide. At the top of this area, south of the Grand Banks, there is a red star representing the epicentre of an earthquake; yellow and orange dots indicating locations where telegraph cables were severed by the submarine landslide. The yellow dots are locations of cables that were severed immediately and orange dots are locations of cables that were severed progressively through time.
