1929 Grand Banks earthquake

On November 18, 1929, 17 against clock, an earthquake of magnitude 7.2, the Grand Banks off Newfoundland, Canada. The earthquake caused no major damage because the epicenter was about 250 kilometers south of the sea. However, the quake triggered a tsunami. A total of three waves hit the Burin Peninsula, killing 28 people and made 10,000 homeless. The cause of the tsunami, an underwater slide could be determined, which destroyed about a dozen submarine cable. The temporal sequence of failures and the approximately known position of the cable allowed to reconstruct the extent and direction of the landslide. This has been recognized that the mass movement has gone unusually far and fast. The reason is thought that there had been a turbidity current ( turbidite ) from water-rich sediments.
