QUESTION 1

1. For the HKPS station , what was the arrival of the P wave arrival time? All waves arrived in the 3 o’clock hour so please omit that and simply put the minute and second information below. Remember to use the website https://www.calculatorsoup.com/calculators/time/time-to-decimal-calculator.php to convert your minutes and seconds into units of just minutes (see announcement).

For example, if you said one of the earthquake waves arrived at 3 o’clock, 25 minutes and 45 seconds, omit the 3 o’clock (input 0 for hours), input 25 minutes and 45 seconds into the website above, and out would come 25.75 min (this is what you’d submit). Another example is if you believe the earthquake wave came in at 3 o’clock, 32 min and 20 seconds, you would put 0 in for hours, 32 min, and 20 seconds into the website and get 32.3333 min (this is what you’d submit).

QUESTION 7

1. For the HKPS station , what was the S-P time difference? All waves arrived in the same hour so the time difference should only be in units of minutes and seconds. Remember to use the website https://www.calculatorsoup.com/calculators/time/time-to-decimal-calculator.php to convert your minutes and seconds into units of just minutes (see announcement).

For example, if you said the S-P time difference was 6 minutes and 10 seconds, put 0 hours, 6 minutes, and 10 seconds into the calculator above and out would come 6.1667 min. This is what you would input for your answer below
