A tsunami is a sort of pulse or “wave packet” consisting ofseveral crests and troughs that become dramaticallylarge as they enter shallow water at the shore. Supposea tsunami of wavelength 235 km and velocity 550 km/htravels across the Pacific Ocean. As it approaches Hawaii,people observe an unusual decrease of sea level in theharbors. Approximately how much time do they have torun to safety? (In the absence of knowledge and warning,people have died during tsunamis, some of them attractedto the shore to see stranded fishes and boats.)

Storms in the South Pacific can create waves that travel all the way to the California coast, 12,000 km away. How long does it take them to travel this distance if they travel at 15.0 m/s?
What is the wavelength of an earthquake that shakes you with a frequency of 10.0 Hz and gets to another city 84.0 km away in 12.0 s?
The intensity of an earthquake wave travelling through the Earth and detected 100 kmfrom the source is 1.0 x 106 W/m2 calculatei) the total power emitted by the sourceii) the intensity at a distance of 400 km from the source
P and S waves from an earthquake travel at different speeds, and thisdifference helps locate the earthquake “epicenter” (where the disturbancetook place). Assuming typical speeds of 8.5km/s and 5.5 km/s for P and Swaves, respectively, how far away did an earthquake occur if a particularseismic station detects the arrival of these two types of waves 1.5 minapart?
In 2004 a massive 10-30m high tsunami was created in the eastern Indian Ocean by anearthquake in Sumatra resulting in the loss of hundreds of thousands of lives. The coast of Africa lies7000km to the west of Sumatra. Knowing that tsunami’s propagate at a speed v = √gH, how longdid it take for the tsunami to strike Africa?
Calculate the wave velocity of the ocean wave, if the distance between wave crests is 10.0 m and the time for a sea gull to bob up and down is 5.00 s.
When a earthquake occurs, transverse and longitudinal waves are produced. These waves do not have the same speed, so one way to detect the hypocenter of the earthquake is to know the time difference between the waves. If the transversal ones travel at 14.5 km/s and the longitudinal ones at 7.8 km/s, at what depth did the earthquake occur if they reach the epicenter 14 seconds apart?
It is estimated that the tsunami which struck Japan on March 11, 2011 had a wavelength of 200.0 km, frequency of 0.0625 min, and amplitude of 7.0 m. What was the velocity, in km/min, of the tsunami before it came ashore?
A tsunami is detected at 12:00 h on the edge of the continental shelf by a warning system. a) At what time can the tsunami be expected to reach the shoreline? b) if the tsunami height was 10 cm at the continental shelf, what is its height at the shoreline?
A geological disturbance in California produces seismic waves which are detected in Phoenix, approximately 990 km from the epicenter. If the waves travel 6.3 km/s, determine the time delay between the disturbance and the detection.
The captain of a crab boat on the coast of Alaska notes that in a time period of t = 8 minutes, the boat goes up and down n= 26 times. Input an expression for the frequency of the ocean wave, f. What is the frequency, in hertz? If the crests are d = 100.0 m apart how fast are the waves traveling in meters per second?
The velocity of the transverse waves produced by an earthquake is 6.07km/s, while that of the longitudinal waves is 11.2902km/s. A seismograph records the arrival of the transverse waves 49s after that of the longitudinal waves. How far was the earthquake in km?
