1 00:00:00,000 --> 00:00:03,990 pation and we can't really just ignore the three-dimensional component of it 2 00:00:03,990 --> 00:00:09,900 and for the work I'm going to show you I actually work on earthquakes at an 3 00:00:09,900 --> 00:00:14,040 earthquake sequence that was triggered by another earthquake very, very far away 4 00:00:14,040 --> 00:00:17,820 and so not only do I have a three-dimensional problem but I also 5 00:00:17,820 --> 00:00:26,670 have a four dimensional problem because time is also another component of it so 6 00:00:26,670 --> 00:00:32,070 this is a pretty typical way that you will see seismologist display 7 00:00:32,070 --> 00:00:38,489 earthquakes so to orient you on the top we have that 2d map projection and so 8 00:00:38,489 --> 00:00:42,989 right here this black line is the trench you've got the incoming plate with the 9 00:00:42,989 --> 00:00:46,309 overriding plate I've got some triangles on here those are my different 10 00:00:46,309 --> 00:00:50,250 seismometers I've got ocean bottom seismometers and the inverted triangles 11 00:00:50,250 --> 00:00:54,870 and some land-based stations right here along the Marianas island arc in the 12 00:00:54,870 --> 00:00:59,579 western Pacific and these dots here represent different earthquakes and so 13 00:00:59,579 --> 00:01:04,619 on the bottom you also have a depth slice or a cross section and this shows 14 00:01:04,619 --> 00:01:08,939 you've got a slab surface right here and you've got the different depths of your 15 00:01:08,939 --> 00:01:12,750 earthquakes here but this is gonna summarize this entire lateral extent and 16 00:01:12,750 --> 00:01:17,280 so when you're trying to differentiate a cluster say up here you can't really 17 00:01:17,280 --> 00:01:21,990 differentiate it that well up here and so like I said I work with triggered 18 00:01:21,990 --> 00:01:27,479 earthquakes so there's a temporal aspect to it so what we have right here is me 19 00:01:27,479 --> 00:01:33,890 trying to explain how that temporal aspect works so this left figure here is 20 00:01:33,890 --> 00:01:40,409 36 hours of events before our triggering event and then this figure over here is 21 00:01:40,409 --> 00:01:45,509 the 36 hours after the triggering event and as well I wanted to point out I do 22 00:01:45,509 --> 00:01:49,530 have some red dots where I try to differentiate a certain events that 23 00:01:49,530 --> 00:01:54,390 happened within the first hour after the event happened and so you can see 24 00:01:54,390 --> 00:02:00,049 there's a cluster at the top here and this is the one that I want to point out 25 00:02:00,049 --> 00:02:05,070 but these maps I'd have to make several panes of them if I wanted to see it show 26 00:02:05,070 --> 00:02:09,030 you kind of a time sequence and that gets kind of cumbersome so while we do 27 00:02:09,030 --> 00:02:12,860 pretty good to show our in-space correlation 28 00:02:12,860 --> 00:02:15,580 it's not really great for in time 29 00:02:19,060 --> 00:02:22,000 so one way we can think about in time is when 30 00:02:22,010 --> 00:02:26,630 we look at the seismograms themself and so these are both on the same station 31 00:02:26,630 --> 00:02:33,320 showing vertical displacement in the same station and on the top I have a low 32 00:02:33,320 --> 00:02:36,830 frequency filter on that and that low frequency filter is going to illuminate 33 00:02:36,830 --> 00:02:41,780 that tel-a-seismic event coming from a distance of five thousand kilometers 34 00:02:41,780 --> 00:02:45,980 away and so by the time it's reached my station it will have lost all that high 35 00:02:45,980 --> 00:02:49,940 frequency energy and so you just see this low-frequency kind of a loser 36 00:02:49,940 --> 00:02:54,080 wiggle to it and when I look at that same hour and a half the same station 37 00:02:54,080 --> 00:02:58,850 everything's the same and free filter it at a higher frequency what I can see is 38 00:02:58,850 --> 00:03:02,570 these events or events that are happening in my local area because they 39 00:03:02,570 --> 00:03:07,190 have not lost that high frequency energy and so what I want to point you to is 40 00:03:07,190 --> 00:03:12,380 this is my S wave arrival for the fir...., for the tel-a-seismic earthquake with my 41 00:03:12,380 --> 00:03:19,760 rayleigh wave here and then right after that event it'll go you see a burst of 42 00:03:19,760 --> 00:03:23,900 different earthquakes here and so this does a good example or a good job of 43 00:03:23,900 --> 00:03:29,150 trying to explain the temporal correlation between these two things but 44 00:03:29,150 --> 00:03:32,480 we really don't know where these things are we'd have to locate them or I'd have 45 00:03:32,480 --> 00:03:36,080 to tell you it doesn't really do a good job visualizing it and so we're thinking 46 00:03:36,080 --> 00:03:40,670 about not only communicating it to other scientists but communicating it to 47 00:03:40,670 --> 00:03:45,620 classrooms and the public this is a little bit hard to grasp 48 00:03:47,820 --> 00:03:54,140 so the Fawcett laboratory okay the Fawcett laboratory at Washington 49 00:03:54,140 --> 00:04:00,500 University has been developing some applications with augmented reality and 50 00:04:00,500 --> 00:04:05,900 this is very similar to virtual reality but you're able to see through and see I 51 00:04:05,900 --> 00:04:09,950 do it's like kind of a mixed reality and so this way you kind of have like a 52 00:04:09,950 --> 00:04:13,370 hologram in front of you and what's nice about this is a little more intuitive 53 00:04:13,370 --> 00:04:16,400 and you can use it to share your experience with other people in the 54 00:04:16,400 --> 00:04:21,500 classroom or in a public setting so here I have my collaborator Martin Pratt and 55 00:04:21,500 --> 00:04:26,310 he has this kind of visor looking thing on there that is the microsoft holo-lens 56 00:04:26,310 --> 00:04:31,470 which helps with this holographic presentation so when it kind of zooms 57 00:04:31,470 --> 00:04:35,220 back out you'll see this purple thing here that is that subducting slab that's 58 00:04:35,220 --> 00:04:40,169 a Mariana slab there and then as he's playing this temporarily back and forth 59 00:04:40,169 --> 00:04:45,090 you can see the earthquakes pop up and if we add sound you can actually hear 60 00:04:45,090 --> 00:04:51,419 sound to this so you'll hear the earthquakes kind of arriving so let play 61 00:04:51,419 --> 00:04:57,330 it one more time so here you also got your seismic stations on the top and so 62 00:04:57,330 --> 00:05:01,560 you see the earthquake starting to pop up and he can look around that cluster 63 00:05:01,560 --> 00:05:05,660 and he can really see that cluster highlight right there 64 00:05:15,560 --> 00:05:22,949 and so because getting a bunch of these holo lenses can be pretty expensive and 65 00:05:22,949 --> 00:05:28,319 maybe a barrier they've also worked to right here Hannah has the hololens on 66 00:05:28,319 --> 00:05:32,069 but Martin's actually recording this and interacting with it with an iPhone and 67 00:05:32,069 --> 00:05:36,060 so you can have iPhones and androids actually sync up together so they're 68 00:05:36,060 --> 00:05:41,069 seeing the same things you could have a professor who is controlling the 69 00:05:41,069 --> 00:05:45,960 animations etc and you can have students be able to actually explore a subduction 70 00:05:45,960 --> 00:05:49,740 zone together and so here in this one you can actually see the two events that 71 00:05:49,740 --> 00:05:53,280 triggered my earthquakes over there in the distance so you could literally walk 72 00:05:53,280 --> 00:05:57,690 from those events over to the Marianas subduction zone you see the events now 73 00:05:57,690 --> 00:06:01,919 he's colored them in different colors to indicate before and after the triggering 74 00:06:01,919 --> 00:06:07,259 event as well and so she can interact and and play 75 00:06:07,259 --> 00:06:14,729 through these events and he's able to watch what she's doing and so this is 76 00:06:14,729 --> 00:06:19,169 something actually you guys can do here the Fossett Laboratory has released two 77 00:06:19,169 --> 00:06:25,409 iPhone apps geo explorer they also use this for they use high resolution 78 00:06:25,409 --> 00:06:31,919 photogramy of outcrops so you can bring those field trips into the lab so the 79 00:06:31,919 --> 00:06:36,539 geo explorer has a bunch of outcrops not only from Earth but they can you can 80 00:06:36,539 --> 00:06:41,190 walk on Mars you can walk on the moon as well and then seismicity AR it's similar 81 00:06:41,190 --> 00:06:45,690 to this one except for its using the USGS Earthquake catalog so you can walk 82 00:06:45,690 --> 00:06:51,479 around the USGS as earthquakes just like Hannah is right here and so I highly 83 00:06:51,479 --> 00:06:55,830 recommend checking out virtual planet booster video the URL down at the end 84 00:06:55,830 --> 00:06:59,969 and if you have any questions feel free to connect with me on Twitter seismo 85 00:06:59,969 --> 00:07:06,509 Amanda any time and thank you
