Information has just come in via satellite that a tsunami has been located off Hilo, Hawaii. The tsunami is at an ocean depth of 4500m. National authorities are trying to establish how
much preparation time the following cities will have:
San Diego, California
Newport, Oregon
Kodiak, Alaska
.
The national authorities have contacted you to compute the amount of time before the
tsunami reaches each of the above locations. As a scientist and mathematician you know
that the speed of tsunamis can be modeled by:
S(d) = 9.80
where d is the depth of the tsunami in meters
S(d) gives the speed of the tsunami in meters per second
Use this equation for speed, the internet to find the distance from Hilo to the above three
cities, and your knowledge of rates to calculate the time it will take for the tsunami to reach
each location. This calculation is an approximation. Round to 2 decimal places and be sure
to use appropriate units. 1) km/hr : of the Hilo tsunami:. 2) km: From Hilo to San Diego . From Hilo to Newport . From Hilo to Kodiak . 3) hr and min: From Hilo to San Diego . From Hilo to Newport . From Hilo to Kodiak. 4) Are there any concerns you have with validating the reasonableness of your solution? 5)what are some factors that may play a role in the speed at which a tsunami travels? 6)Seismology have just registered a large underwater earthquake near Sand point Alaska that is big enough to produce a tsunami. The ocean depth is unknown but it took 5hrs to reach Monterey California. Estimate the depth of the ocean where the tsunami originated.
