- Over a great circle route between an earthquake epicentre off the coast of Chile and Hawaii the average depth is 100m for 150 n.m. (1 nautical mile = 1852 m), 3300m for 390 nautical miles, 4000m for 3800 nautical miles and 5200m for 1300 nautical miles. The earthquake creates a wave in a water depth of 1300m with a period of 40 min and a height, Ho, of 0.9 m. By calculating the wavelength, phase speed, and tsunami travel time for each part of the great circle route, determine the total travel time between the epicentre and endpoint of the route. Give your answer in hours, rounded to two decimal places.A ship's model of scale 1: 100 had a wave resistance of 1 N at its design speed.
