Tsunami Travel Time Maps: Look at the Tsunami Travel-Time Map below. This shows the expected travel time of the first tsunami waves generated by the Kuril Islands earthquake. The earthquake, which generated the marigram you used in the questions above, was located in the central Kuril Islands region where the ψ

is marked. 14. How long (round off to the nearest 1/2 hour) did it take the first tsunami wave to travel from the epicenter region of the Kuril Islands earthquake to Crescent City (notes with a ) ) ​
15. The distance between the epicenter of the Kuril Islands earthquake and Crescent City is about 3700 miles. What was the average velocity of the first wave on the Crescent City record? (Hint: Velocity is a rate of distance over time.)
