Question 6 (3 points) An earthquake emits both S-waves and P-waves which travel at different speeds through the earth. An S-wave travels at 5000 m/s and a P-wave travels at 9000 m/s. If S-waves are received at a seismic station one minute after a P-wave arrives, then how far away is the earthquake center? 88.9 km 240 km 480 km 675 km 1200 km

When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, or P, wave has a speed of about 8.0 km/s and the secondary, or S, wave has a speed of about 4.5 km/s. A seismograph, located some distance away, records the arrival of the P wave and then, 117 s later, records the arrival of the S wave. Assuming that the waves travel in a straight line, how far (in terms of...

Earthquake Lab: Locating the Epicenter, Determining the Magnitude, and Calculating the Time of Earthquake The goal of this lab is to learn how seismograms are used to locate the epicenter of earthquakes, determine earthquake magnitudes, and to calculate the origin time of earthquakes. A seismogram measures the amount of shaking caused by earthquake waves. The seismogram first records the arrival of P-Waves (Primary), followed by the arrival of the S-Waves (Secondary). The S-P interval is the time difference between the...

QUESTION 2 Earthquakes produce several types of shock waves, two of which are called S and P waves. P waves travel at about 6.5 km/s, and S waves travel at about 3.5 km/s. The delay in arrival times between P waves and S waves provides from the measurement station. If a station records a delay of 33 s, how far from the station was the earthquake (ín kilometers? Use two significant figures in your answer. information about how far away...
An earthquake 55 km from a city produces P and S waves that travel outwards at 5000 and 3000 m/s, respectively.
An earthquake 55 km from a city produces P and S waves that travel outwards at 5000 and 3000 m/s, respectively.Part AOnce city residents feel the shaking of P wave, how much time do they have before the S wave arrives?

3. Earthquake warning system A typical earthquake produces two types of seismic waves. P ("primary" seismic waves are longitudinal waves that move through the earth's upper crust with speed anywhere from 3 km/s to 5 km/s (the exact speed depends on the local composition of the earth's crust). S ("secondary") waves are transverse waves that move slower than P waves. The S-wave speed is typically about 60% less than the P-wave speed in any given material. The map below shows...

002 10.0 points Earthquakes produce two kinds of seismic waves: he longitudinal primary waves (called P waves) and the transverse secondary waves (called S waves). Both S waves and P waves travel through Earth's crust and mantle, but at different speeds; the P waves are always faster than the S waves, but their exact speeds depend on depth and location. For the pur- pose of this exercise, we assume the P wave's speed to be 8380 m/s while the S...

Suppose that p- and s-waves traveled in straight lines through the Earth (in fact, they don't, but we will make this approximation for this problem). Also suppose that the angular distance from the epicenter (location of the earthquake) on the Earth's spherical surface to the location on the surface beyond which no s-waves can be observed from an earthquake (the angle between the earthquake epicenter and the s shadow zone) is 120 degrees (i.e., the two points are located 1/3...

12. The waves from a radio station can reach a home receiver by two paths. One is a straight- line path from transmitter to home, a distance of 30.0 km. The second is by reflection from the ionosphere (a layer of ionized air molecules high in the atmosphere). Assume this reflection takes place at a point midway between receiver and transmitter, the wavelength broadcast by the radio station is 350 m, and no phase change occurs on reflection. Find the...
