The time duration of earthquake = Duration Between first and last tremor = 10:45:12 - 00:54:57

For ease of calculation, let's assume that first tremor was at 00:45:12
Number of hours between 00:45:12 and 10:45:12 = 10 Hours = 10 * 60 *60 seconds = 36000 seconds

But in reality, its less than 10 hours as tremors started at 00:54:57 instead of 00:45:12
So time duration between 00:54:57 and 00:45:12 = 9 minutes 45 seconds = 585 seconds

The total duration of the earthquake in seconds = 36000 - 585 = 35415
The tremor was felt every 15 seconds so the number of times tremor was felt in 35415 seconds = 35415/15 = 2361
