WEBVTT

1
00:00:00.080 --> 00:00:02.200
<v Speaker 1>I want to mention something that's fascinating. If people go

2
00:00:02.240 --> 00:00:05.360
<v Speaker 1>to USGS dot gov, this is fascinating. The past day,

3
00:00:06.080 --> 00:00:09.839
<v Speaker 1>thirty nine earthquakes worldwide and I'm amazed at this. So

4
00:00:10.039 --> 00:00:13.519
<v Speaker 1>USGS is incredible. I want you to describe the organization

5
00:00:13.679 --> 00:00:17.280
<v Speaker 1>the government agency in the moment. But I'm looking here, doctor,

6
00:00:17.480 --> 00:00:20.519
<v Speaker 1>fifty four earthquakes the other day. Thirty nine earthquakes in

7
00:00:20.559 --> 00:00:23.120
<v Speaker 1>the recent twenty four hours, and some as high as

8
00:00:23.160 --> 00:00:26.280
<v Speaker 1>a six point two on the Richter scale. That's incredible.

9
00:00:26.320 --> 00:00:28.399
<v Speaker 1>I mean, is that something you see all the time,

10
00:00:28.480 --> 00:00:31.079
<v Speaker 1>that number of earthquakes or is this something that's just all.

11
00:00:31.160 --> 00:00:34.719
<v Speaker 2>The time to you all the time. And so the

12
00:00:34.799 --> 00:00:38.159
<v Speaker 2>thing is, so let's talk a little bit about earthquakes

13
00:00:38.159 --> 00:00:42.960
<v Speaker 2>and why yes, absolutely well, we think of the Earth

14
00:00:43.039 --> 00:00:46.920
<v Speaker 2>we live on as something that's rigid, solid and just

15
00:00:47.240 --> 00:00:51.520
<v Speaker 2>completely sturdy, but the Earth is really a dynamic planet.

16
00:00:51.960 --> 00:00:56.679
<v Speaker 2>There's always motion happening at depth, and we are living

17
00:00:56.759 --> 00:01:02.000
<v Speaker 2>on the very very very surface cross the cross of

18
00:01:02.039 --> 00:01:05.000
<v Speaker 2>the Earth is really really not thick. I mean, in

19
00:01:05.040 --> 00:01:09.359
<v Speaker 2>the ocean's five to ten kilometers and the continental continental

20
00:01:09.439 --> 00:01:13.599
<v Speaker 2>cross is twenty five feet seventy kilometers of fifteen to

21
00:01:13.680 --> 00:01:16.760
<v Speaker 2>forty fifty forty five miles. It's not that sick. I

22
00:01:16.760 --> 00:01:19.120
<v Speaker 2>mean when you think of the radius of the earth,

23
00:01:19.200 --> 00:01:21.959
<v Speaker 2>which is what doctor skuy yes, if.

24
00:01:21.799 --> 00:01:24.280
<v Speaker 1>You look at it, I look at the right, I

25
00:01:24.400 --> 00:01:28.400
<v Speaker 1>look at the diameter, and twenty six miles. I guess

26
00:01:28.480 --> 00:01:31.400
<v Speaker 1>I'm stuck on mileage. And you know, it's amazing doctor,

27
00:01:31.439 --> 00:01:34.040
<v Speaker 1>the guest that we have. Everybody talks, I guess in

28
00:01:34.079 --> 00:01:37.519
<v Speaker 1>the scientific term of kilometers. But maybe I better get

29
00:01:37.519 --> 00:01:39.959
<v Speaker 1>with the program and understand the conversion, right.

30
00:01:40.680 --> 00:01:45.319
<v Speaker 2>Well, yes, yes, but anyways, just a matter of scale,

31
00:01:45.719 --> 00:01:49.560
<v Speaker 2>this is we're just if you think of you blow

32
00:01:49.599 --> 00:01:52.599
<v Speaker 2>bubbles with soap, we're just the surface of that. That's

33
00:01:52.640 --> 00:01:55.719
<v Speaker 2>where we're. So that's a cross and there's multiple layers

34
00:01:55.760 --> 00:01:58.480
<v Speaker 2>in the earth, and you know, there's a core that's solid,

35
00:01:58.519 --> 00:02:01.640
<v Speaker 2>there's a part that that liquid, and then there's the

36
00:02:01.760 --> 00:02:06.480
<v Speaker 2>mantle that's kind of a transition transitional space there. And

37
00:02:06.519 --> 00:02:09.840
<v Speaker 2>the crust is really the upper stiff part that is there.

38
00:02:10.400 --> 00:02:15.520
<v Speaker 2>And what happens in the mantle underneath us it's semi fluids,

39
00:02:15.719 --> 00:02:21.159
<v Speaker 2>it's not completely solid. There's convection cells underneath, and and

40
00:02:21.199 --> 00:02:25.439
<v Speaker 2>what what is a convection convection cell is that you

41
00:02:25.560 --> 00:02:31.800
<v Speaker 2>have a motion of matter and heat that goes kind

42
00:02:31.800 --> 00:02:34.319
<v Speaker 2>of in a circle and it kind of feeds things

43
00:02:34.439 --> 00:02:39.280
<v Speaker 2>like your one what do you call that? The what

44
00:02:39.879 --> 00:02:43.719
<v Speaker 2>do you call that? I'm sorry? In the airport, the

45
00:02:44.360 --> 00:02:52.879
<v Speaker 2>the thing that moves so the crust, the crust is

46
00:02:52.960 --> 00:02:56.800
<v Speaker 2>pushed by you know, like a conveyor belt. And physically

47
00:02:57.240 --> 00:03:01.520
<v Speaker 2>we have if you remember from like let me country school, great,

48
00:03:01.879 --> 00:03:07.000
<v Speaker 2>you know high school, there's a lot of there's tectonic plates, right,

49
00:03:07.039 --> 00:03:10.599
<v Speaker 2>So the cross itself is kind of formed by these

50
00:03:10.759 --> 00:03:14.919
<v Speaker 2>these shapes that embricate next to each other and they're

51
00:03:14.960 --> 00:03:18.240
<v Speaker 2>just touching each other, and we have not underneath imagine

52
00:03:18.280 --> 00:03:21.520
<v Speaker 2>these convection cells that really want to push the plates

53
00:03:21.520 --> 00:03:27.159
<v Speaker 2>and move them. So the earth is there and there's

54
00:03:27.199 --> 00:03:31.039
<v Speaker 2>always this motion, and eventually the plates they want to move,

55
00:03:31.120 --> 00:03:35.039
<v Speaker 2>they want to move, and eventually those the forces are

56
00:03:35.080 --> 00:03:38.919
<v Speaker 2>too strong and something breaks and that creates an earthquake.

57
00:03:39.439 --> 00:03:42.879
<v Speaker 2>And the biggest earthquakes, as you mentioned, along the Pacific

58
00:03:43.840 --> 00:03:46.520
<v Speaker 2>Ring of Fire, they happen in the in the zone,

59
00:03:46.960 --> 00:03:52.719
<v Speaker 2>in subduction zones where the oceanic crust those under the

60
00:03:52.800 --> 00:03:57.560
<v Speaker 2>continental cross and creates massive earthquakes. And then after that

61
00:03:57.639 --> 00:03:59.960
<v Speaker 2>there's other areas where there's a little bit less act,

62
00:04:01.319 --> 00:04:03.039
<v Speaker 2>and if you're in the middle of the continent, you

63
00:04:03.080 --> 00:04:06.199
<v Speaker 2>would think, well, you know, that's completely stable. There's still

64
00:04:06.240 --> 00:04:09.360
<v Speaker 2>a lot of forces happening there that even though you're

65
00:04:09.439 --> 00:04:13.159
<v Speaker 2>far away from a limit or the contact of a tectonically,

66
00:04:13.599 --> 00:04:16.040
<v Speaker 2>there's still a lot of forces. And at some point

67
00:04:16.319 --> 00:04:20.600
<v Speaker 2>the crust just a little bit, and an earthquake is

68
00:04:20.680 --> 00:04:25.560
<v Speaker 2>just the material that breaks very fast, and that's what

69
00:04:25.720 --> 00:04:31.480
<v Speaker 2>causes earthquake. And the Earth is constantly adjusting, and so

70
00:04:31.600 --> 00:04:34.120
<v Speaker 2>these earthquakes happen all over the world all the.

71
00:04:34.120 --> 00:04:36.959
<v Speaker 1>Time, a living, breathing entity of the Earth, as doctor

72
00:04:36.959 --> 00:04:39.879
<v Speaker 1>Gouley is describing, getting in in the theater of the mind,

73
00:04:40.160 --> 00:04:43.480
<v Speaker 1>your conversation and your questions, of course, makes the show possible.

74
00:04:44.040 --> 00:04:47.079
<v Speaker 1>With of course are great. Yes, the contact number one

75
00:04:47.120 --> 00:04:49.720
<v Speaker 1>eight hundred eight four eight nine two two two. We

76
00:04:49.800 --> 00:04:52.519
<v Speaker 1>hope that everybody out there will have questions and concerns

77
00:04:52.519 --> 00:04:55.319
<v Speaker 1>about earthquakes, as we did do a deep dive into

78
00:04:55.360 --> 00:04:57.759
<v Speaker 1>this interesting subject. I want to bring something to the

79
00:04:57.839 --> 00:05:00.360
<v Speaker 1>attention of people on the West coast of the United

80
00:05:00.399 --> 00:05:03.519
<v Speaker 1>States and see your contribution to this. In your opinion,

81
00:05:03.879 --> 00:05:06.879
<v Speaker 1>the Cascadia Subduction Zone. This is an area, as you

82
00:05:06.959 --> 00:05:09.839
<v Speaker 1>probably know better off the Oregon coast and in the

83
00:05:09.879 --> 00:05:13.439
<v Speaker 1>year seventeen hundred, this incredible, they say, and I'm reading

84
00:05:13.480 --> 00:05:16.639
<v Speaker 1>this eight point seven to nine point two earthquake happened

85
00:05:16.759 --> 00:05:21.040
<v Speaker 1>off the coast of Oregon, creating a gigantic tsunami and

86
00:05:21.120 --> 00:05:23.920
<v Speaker 1>also it being felt over all the way across the

87
00:05:23.959 --> 00:05:26.920
<v Speaker 1>ocean to Japan. But here's the concern, and not to

88
00:05:26.959 --> 00:05:29.680
<v Speaker 1>alarm people if they're listening to us in Oregon or Washington,

89
00:05:30.560 --> 00:05:33.720
<v Speaker 1>that probably was one of the most devastating near part

90
00:05:33.759 --> 00:05:36.480
<v Speaker 1>of the United States, I think in recent history. But

91
00:05:36.600 --> 00:05:39.360
<v Speaker 1>isn't that incredible? I mean, describe that because could it

92
00:05:39.759 --> 00:05:44.079
<v Speaker 1>eventually slip again? This san Juanda Fuca I guess plate

93
00:05:44.439 --> 00:05:49.040
<v Speaker 1>off the coast of California, Oregon and moving up into Canada.

94
00:05:49.160 --> 00:05:52.199
<v Speaker 1>That's an incredible stories that you can comment on. That's amazing.

95
00:05:53.279 --> 00:05:58.120
<v Speaker 2>Yes, absolutely, And there's again so I know it's hard

96
00:05:58.199 --> 00:06:01.680
<v Speaker 2>to explain. I'm gonna try to explain that visually. It's

97
00:06:01.720 --> 00:06:05.560
<v Speaker 2>already talked about those tectonic plates, right, and the Earth

98
00:06:05.600 --> 00:06:08.319
<v Speaker 2>doesn't change volume, it doesn't grow, it doesn't shrink, it's

99
00:06:08.319 --> 00:06:12.560
<v Speaker 2>the same, so it needs to when something moves, if

100
00:06:12.600 --> 00:06:17.720
<v Speaker 2>something something is created, something needs to get destructive. And

101
00:06:17.759 --> 00:06:20.279
<v Speaker 2>what we have in the middle of our oceans is

102
00:06:20.360 --> 00:06:24.079
<v Speaker 2>those ridges where there's new cross that forms and it

103
00:06:24.160 --> 00:06:28.279
<v Speaker 2>pushes the oceanic cross towards the continent and then it

104
00:06:28.399 --> 00:06:32.360
<v Speaker 2>arrives near the continent, and the oceanic crust is very dense,

105
00:06:32.480 --> 00:06:36.839
<v Speaker 2>much denser than the continental cross, and it kind of

106
00:06:37.000 --> 00:06:40.199
<v Speaker 2>sinks on the neat right, and I'm simplifying here. It

107
00:06:40.319 --> 00:06:42.959
<v Speaker 2>sinks a little bit. But as it sinks and it

108
00:06:43.120 --> 00:06:47.160
<v Speaker 2>dies into it, really it sticks in it. And that's

109
00:06:47.199 --> 00:06:52.319
<v Speaker 2>what creates those earthquakes. And so this subduction zone, that's

110
00:06:52.319 --> 00:06:55.000
<v Speaker 2>what it means. Subduction is going on there. It's the

111
00:06:55.000 --> 00:06:57.879
<v Speaker 2>oceanic cross that goes on there. And that's what's happening

112
00:06:57.879 --> 00:07:00.600
<v Speaker 2>on the all the West coast actually not just America,

113
00:07:00.920 --> 00:07:06.360
<v Speaker 2>South America as well Chile. The largest ever recorded earthquake

114
00:07:06.399 --> 00:07:09.600
<v Speaker 2>in nineteen sixty was a nine point five just offshore

115
00:07:09.639 --> 00:07:10.480
<v Speaker 2>of Chile.

116
00:07:10.680 --> 00:07:11.199
<v Speaker 1>So amazing.

117
00:07:12.199 --> 00:07:17.439
<v Speaker 2>Yeah, it happened also in Cascadia. It will happen again

118
00:07:17.720 --> 00:07:20.439
<v Speaker 2>when we don't know exactly when, but for sure it

119
00:07:20.480 --> 00:07:23.560
<v Speaker 2>will happen again. It's going to be similar to what

120
00:07:23.800 --> 00:07:28.639
<v Speaker 2>was seen in Japan just a few years ago, or

121
00:07:28.680 --> 00:07:32.319
<v Speaker 2>Indonesia in two thousand and four. These types of earthquakes

122
00:07:32.360 --> 00:07:34.800
<v Speaker 2>are subduction earthquakes.

123
00:07:35.040 --> 00:07:37.160
<v Speaker 1>And I got a point to bring up here, doctor,

124
00:07:37.279 --> 00:07:40.959
<v Speaker 1>this is amazing according to the information I'm getting here,

125
00:07:41.439 --> 00:07:43.439
<v Speaker 1>the wand if you could play it off, that Pacific

126
00:07:43.480 --> 00:07:48.279
<v Speaker 1>Ocean area only slipped by sixty six feet. Now imagine

127
00:07:48.279 --> 00:07:50.199
<v Speaker 1>we can measure and look at what sixty six feet

128
00:07:50.319 --> 00:07:53.959
<v Speaker 1>is causing that much of a disturbance in in an ocean,

129
00:07:54.439 --> 00:07:57.680
<v Speaker 1>causing a tsunami to be felt. And according to this report,

130
00:07:57.720 --> 00:08:01.399
<v Speaker 1>it states that inland in Oregon way back, a massive

131
00:08:01.439 --> 00:08:04.600
<v Speaker 1>title wave wiped out a big portion of forest over there.

132
00:08:04.600 --> 00:08:08.639
<v Speaker 1>So the earth is obviously, you know, constantly changing, constantly,

133
00:08:08.639 --> 00:08:12.240
<v Speaker 1>a dynamic in dynamic events, that's just incredible for people

134
00:08:12.279 --> 00:08:12.959
<v Speaker 1>to comprehend.

135
00:08:14.319 --> 00:08:18.480
<v Speaker 2>It's absolutely fascinating. It's a force of nature that when

136
00:08:18.519 --> 00:08:21.759
<v Speaker 2>you go through, you live through an earthquake, you realize

137
00:08:21.800 --> 00:08:25.319
<v Speaker 2>that nature is extremely powerful. And you mentioned the tsunami.

138
00:08:25.399 --> 00:08:28.800
<v Speaker 2>There's multiple mechanisms that cause that. But we have this subduction.

139
00:08:29.399 --> 00:08:33.279
<v Speaker 2>So imagine that the oceanic cross again is diving underneath,

140
00:08:33.320 --> 00:08:35.840
<v Speaker 2>gets stuck, gets stuck, and then there's an earthquake, it

141
00:08:35.879 --> 00:08:40.120
<v Speaker 2>gets relieved sometimes and quite often what will happen is

142
00:08:40.159 --> 00:08:44.080
<v Speaker 2>then the constant across kind of goes down a little bit,

143
00:08:44.720 --> 00:08:48.759
<v Speaker 2>and then the near shore gets flooded, I mean permanently

144
00:08:48.919 --> 00:08:53.360
<v Speaker 2>for a long time. But the tsunami is generated because

145
00:08:53.399 --> 00:08:57.759
<v Speaker 2>there's a sudden motion underneath the ocean. Right, there's southern

146
00:08:57.840 --> 00:09:01.879
<v Speaker 2>movement that can be like sixty right. It just imagine,

147
00:09:02.000 --> 00:09:04.080
<v Speaker 2>well that all the water needs to go somewhere and

148
00:09:04.120 --> 00:09:08.519
<v Speaker 2>to lift big volume, and it needs to go somewhere.

149
00:09:08.639 --> 00:09:13.720
<v Speaker 2>So the tsunami then is generated from the movement of
