Question

Go to the web site www.sciencecourseware.com/VirtualEarthquake (or Google “virtual earthquake”). IfGoogle takes you to a different site, do NOT select Earthquake, which is their “new revised version”, because itdoes not work with some operating systems. At the bottom of the page, choose Execute Virtual Earthquake, besure to choose “San Francisco area” earthquake, and follow the directions for locating an earthquake anddetermining its magnitude. At the end, print your certificate of completion along with its associated tableshowing your calculations. You will not be turning in the certificate itself, but you will use the information inthat table for online submission of this homework. Answer the question 1-21

1.Your measurement (not "actual" time) of the time interval (in seconds) between S & P arrivals at station Eureka is:

2.Your measurement (not "actual" time) of the time interval (in seconds) between S & P arrivals at station Elko is:

3.Your measurement (not "actual" time) of the time interval (in seconds) between S & P arrivals at station Las Vegas is:

4.Your measurement of the distance (in km) from the quake to station Eureka is:

5.Your measurement of the distance (in km) from the quake to station Elko is:

6.Your measurement of the distance (in km) from the quake to station Las Vegas is:

7.Your measurement of the amplitude (in mm) of the largest peak or trough measured at station Eureka is:

8.Your measurement of the amplitude (in mm) of the largest peak or trough measured at station Elko is:

9.Your measurement of the amplitude (in mm) of the largest peak or trough measured at station Las Vegas is:

10.Your measurement of the magnitude of this earthquake is:

11.Magnitude:

12.Amplitude if magnitude 3:

13.At Sandy, the time (in seconds) between P & S arrivals is:

14.At Sandy, the amplitude (in mm) of the largest peak or trough is:

15.The distance (in km) from Sandy to the quake is:

16.The earthquake magnitude is:

17.At UofU, the time (in seconds) between P & S arrivals is:

18.At UofU, the amplitude (in mm) of the largest peak or trough is:

19.The distance (in km) from UofU to the quake is:

20.The earthquake magnitude is:

21.Did you calculate roughly the same magnitude from the two seismograms, as expected if they are detecting the same earthquake?

Explanation / Answer

1) 49s

2) 72s

3) 64s

4) 480km

5) 702 km

6) 612km

7) 285 mm

8) 60mm

9) 100mm

10) 7.1

11) 7.1

12) 1

13) - 21) The earth quake has a rcorded true magnitude of 7.1 as shown int he website. It is named as Loma Prieta earthquake, 1980.. I have checked all four options ie, San Fransisco, California, Mexico and Japan for finding out any refrence to Sandy and UofU mentioned places.  Though, I couldn't find any reference of UofU and Sandy in the website. Hence, I am unable to answerrest of the quiestion. Please feel to comment any additional info by which I can help you.
