Question

Please do not write in cursive

The time at which the first P waves arrived at each of the four stations is shown on the seismograph record. From this information you can determine when the earthquake actually occurred. The time of arrival of the earthquake waves minus the travel time will give you the time the waves originated (when the earthquake happened). To compute travel time use the same formula you used in question 10.8a. When did the quake actually occur? Compute an origin time for P waves arriving at each of the four recording stations. The four origin times should be the same (or close). If some of your answers seem to be an hour different, think about the time difference between the Pacific and Mountain time zones.

Explanation / Answer

The process of occurance of earth quack is due to the movement of techtonics plates as well but the fact is that which region will hitted by it and to compute the time travel of this we have to opt the situation in a grphical way.

From the above data, it is given that four region namely san fransico, los angles salt lake city and alburquer are shown by plotting the graph against them. but the fact which we analyses from the graph is that in case of los angels it is first to be get hitted then san fransico after this salt lake city and at last alberquerque. it all analysed from the graphs.

time for los angels-11:06 pst

san fransisco-11:46 pst

salt lake city- 12:08 mst

alberquerque-12:45 mst
