Example 9:If an earthquake occurs at 08:50:40, what time did the P-wave arrive at a seismic station 2,600 km away? 3) If you are asked for the . arrival time. of an earthquake wave and given an epicenter distance and origin time: a) Determine travel time of the wave (see #1) b) Add travel time to the origin time given. 08:50:40 +00:05:00 ... These vibrations are called seismic waves. The point within the earth where the fault rupture starts is called the focus or hypocenter. This is the exact location within the earth were seismic waves are generated by sudden release of stored elastic energy. The epicenter is the point on the surface of the earth directly above the focus. Sometimes the media get these two terms confused. 1. The epicenter of the earthquake is the point on Earth’s surface closest to the focus, or origin, of the earthquake. A. What symbol represents the epicenter? _____ B. What symbol represents the recording station? _____ 2. Click Play ( ) and observe the seismic waves leaving the epicenter of the earthquake. A. What types of seismic waves are ... giving travel times of seismic waves from an earthquake. Then study the map identi-fying the epicenter of the earthquake. Use these to answer the questions. Seismologists use the distance from an epicenter plus the times of the arrival of primary, secondary, and surface waves to determine the time at which earthquakes begin. 1.

Answers: 1. What creates waves? Waves are created by energy passing through water, causing it to move in a circular motion. 2. What could be an obstruction to waves? Answers will vary, but the answer could be an island or a beach. 3. Why do you think wind is the most common cause of wave creation? Wind is the most common cause of wave creation ... Master 30.

Using data from seismic waves, geologists have learne d that Earth's interior is made up of several layers. Each layer sur-rounds the layers beneath it, much like the layers of an onion. In Figure 3, you can see how seismic waves travel through thethat wave approaches shallower water, it grows in height. Remember, the tsunami travels quickly. If you are sitting on a beach, you may not see the wave coming at first. But when the wave arrives, it will be like a towering wall of water. Some waves are as tall as 100 feet high. Super Teacher Worksheets - www.superteacherworksheets.com Earthquake waves are seismic waves that are created when energy builds up in rocks and they fracture. Scientists estimate there are several million earthquakes each year. Every earthquake produces P waves and S waves but only larger earthquakes produce Love waves and Rayleigh waves. These are the four major types of seismic waves.
Earthquakes, or seismic activity, are recorded by seismographs. When the ground shakes, seismographs oscillate, drawing a jagged line to reflect this movement. The more extreme the earthquake, greater the height of the jagged line. These recorded motions are then used to measure the earthquake’s strength, or magnitude.

Faster waves will travel the distance quicker and show up on the seismogram first. travel time = (distance from earthquake to seismometer) / (seismic wave speed) Travel time is a relative time, it is the number of minutes, seconds, etc. that the wave took to complete its journey. 1. Mark the first arrival of the P‐wave on each seismogram. 2. Mark the first arrival of the S‐wave on each seismogram. 3. Write down your data in the box to the right of each seismogram. 4.

This 4-page worksheet ought to give them the practice that they need. This one is themed around natural disasters. Students will read eleven passages and determine the text structure. of each Then they will put information from the text into the appropriate graphic organizer. Suggested reading level for this worksheet: Grade 6-10. A wave with a frequency of 60.0 Hz travels through steel with a wavelength of 85.5 m. What is the speed of this wave? Earthquakes generate shock waves that travel through Earth’s interior to other parts of the world. The fastest of these waves are longitudinal waves, like sound waves, and are called primary waves, or just p-waves. In 1958, a tsunami generated a wave 1720 feet tall in Lituya Bay, Alaska. This is the largest tsunami on record. Below you will find a series of worksheets on this phenomenon. This activity was developed for use in a high school (grades 9-12) earth science class. The goal of this lesson is for students to gain an understanding of where earthquakes occur, to learn about several historical earthquakes, to learn about local faults in southern California, to learn the concepts of elastic rebound and friction, to learn about seismic waves and seismograms, to learn the ... In Earth we often use an approximation that relates Vp and Vs. Vs = Vp / √3 (2) Substituting Equation 2 into Equation 1 and rearranging yields, D = (S-P) x Vp (√3 -1) Since our seismic waves do not travel deep they remain in the crust where P-waves travel at a velocity of approximately 5.7-6.0 km/s.
