3. Earthquake warning system A typical earthquake produces two types of seismic waves. P ("primary" seismic...
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...
11 In the crust of the earth, seismic waves of the P type have a speed of almost 5 km/s; waves of the S type have a speed of about 3 km/s. Suppose that after an earthquake, a seismometer placed at some distance first registers the arrival of P waves and 9 min later the arrival of S waves. What is the distance between the seismometer and the source of the waves?
Earthquakes at fault lines in Earth's crust create seismic waves, which are longitudinal (P-waves) or transverse (S-waves). The P-waves have a speed of about 7 km/s. Estimate the average bulk modulus of Earth's crust given that the density of rock is about 2500 kg/m3. Pa
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...
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
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?
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...
3. [5 marks] The diagram to the right shows the paths that body waves would take to travel from the source to a series of seismic stations, A through G, if the Earth'so interior was homogeneous. Suppose that the seven seismic stations are spaced at equal distances apart on the Earth's surface and that the angle, ?, is equal to 90 degrees. If the source emits a P-wave at time zero, calculate the time taken for the wave to reach...
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...
