WEBVTT FILE 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
