Tsunamis are series of large ocean waves that can be caused by an underwater volcanic eruption, earthquake or landslide. Tsunamis are dangerous because they can reach up to 500 miles per hour. Due to the enormous threat a tsunami poses, it is important for scientists to track any possible tsunamis that may be occurring. Several tsunami research facilities exist that constantly monitor the movement of the waves in the oceans to ensure that they can give warning to the areas that are in danger. There are two equations that are important for monitoring tsunamis:
In this investigation we will be investigating how fast tsunamis move and how long it takes them to reach varying locations using these equations.
To find the distance from the epicenter to the city you can look up the latitude and longitude of the city and then create a right triangle using the difference in latitudes as one leg and difference in longitudes as the other leg. Then solve for the hypotenuse and use the map scale to turn this into kilometers. Or, you can use a map application online to measure the distance.
For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. Key features include the following: intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity.
