Time transcripts of tsunamiTravelTime [00:00:00:010] This is how you calculate the travel time to one of your stations. [00:00:04:020] We'll stick with station 21418, that's our example [00:00:08:030] station. We picked the arrival time at 70.26 [00:00:12:040] We just need to subtract the origin time of the earthquake [00:00:16:050] which we've already calculated. [00:00:20:050] [00:00:24:070] And here is the answer we get when we subtract these numbers. [00:00:28:080] 0.0195. And remember this is in [00:00:32:090] days. We want to convert this to hours because later we are going to [00:00:36:090] calculate the velocity of the tsunami and we want that to be in kilometers per hour. [00:00:40:100] If we multiply by 24 hours in a day then [00:00:44:100] we can make this number be hours. When we do that, we get [00:00:48:110] 0.468. That is the number of hours it took the [00:00:52:110] tsunami to get from the earthquake to where this station is. A little less than half an hour. [00:00:56:130]
