Within minutes transatlantic telephone cables started sequentially snapping, with the furthest cable - 600km from the quake - breaking 13 hours and 17 minutes later.At the time geologists hypothesised that the cables had been broken by a series of earthquakes, but we now know that the culprit was a massive underwater avalanche, known as a "turbidity current".
