00:00:04 Out of need or curiosity
00:00:07 man has learned much about the Earth on
00:00:09 which he is both guest and prisoner
00:00:12 Often baffled in his brief journey
00:00:15 he has found reassurance in the
00:00:19 the recurring sequence of the seasons
00:00:21 the symmetry in storm
00:00:25 Yet nothing has lessened his terror
00:00:28 when nature seems to turn against him
00:00:30 when the Earth shudders and
00:00:34 making rubble of all he has built
00:00:50 "Twenty thousand people dead;
00:00:52 anywhere from fifty thousand
00:00:54 and fifty thousand injured..."
00:00:55 "If that's it,
00:00:59 The communication may go bad
00:00:59 but that's the angle they ought to go."
00:01:10 "There's two more in there."
00:01:14 Against the sudden blows of
00:01:16 that often strikes without warning
00:01:18 some have tried to create defenses
00:01:21 Powerless to prevent eruption
00:01:24 they seek to diminish its toll
00:01:31 Others light candles of faith
00:01:57 Today new candles light the dark
00:02:02 instruments whose beams are reflected
00:02:06 or catch signals from outer space
00:02:09 to measure the smallest movements
00:02:14 Now man has devised new concepts
00:02:16 of the forces altering
00:02:20 forces that move the continents
00:02:23 twist the globe's thin crust
00:02:25 build vast mountain ranges
00:02:34 Like all living things
00:02:39 Born of fire, it too is being
00:03:31 Once this was blank ocean the cold
00:03:34 storm-swept Atlantic off the
00:03:38 Then, in fiery eruption during
00:03:43 the island of Surtsey began to
00:03:47 Today its single square mile of ash
00:03:50 and lava forms one of
00:03:53 to the land surface of the globe
00:03:55 Yet this virgin terrain is
00:04:00 Already life has found it
00:04:02 Already seeds borne by wind
00:04:05 and wave have taken root in the ash
00:04:07 and birds have begun to
00:04:18 A closed preserve to casual visitors
00:04:21 the island has become a
00:04:24 Here scientists from distant
00:04:28 by which life tests
00:04:29 and gradually seizes a new domain
00:04:33 Among them is Dr. Robert Ballard, geologist
00:04:36 from the Woods Hole Oceanographic
00:04:42 "The story I often tell to try
00:04:45 that the Earth really is alive
00:04:48 if you were to interview a
00:04:51 standing on a branch of a sequoia tree
00:04:55 Now, a butterfly lives for
00:05:00 and a sequoia tree can live
00:05:04 And if you were to ask that butterfly
00:05:05 Do you perceive the object on
00:05:08 which you are standing
00:05:13 And the butterfly would say,
00:05:15 I've been here all my life five days
00:05:19 and the tree hasn't done a thing
00:05:22 Same problem with the human being
00:05:24 If you were to ask a human being
00:05:26 perhaps one that's lived
00:05:29 if they perceive the Earth
00:05:32 and a half billion years in age
00:05:35 they'd probably say
00:05:36 Of course not. I've been here
00:05:38 and it hasn't done a thing.'
00:05:40 But the Earth really is a
00:05:43 In fact, I think of it as
00:05:46 Like Surtsey, Earth too is an island
00:05:52 but in the vaster sea of space
00:05:55 In time beyond the measure of
00:05:58 it too is in slow and ceaseless change
00:06:03 Some two hundred million years ago
00:06:05 its landmasses formed a single
00:06:12 Then slowly, Pangea's fracturing
00:06:17 like pieces of a vast jigsaw puzzle
00:06:19 gradually assuming the shapes
00:06:22 and arrangement we recognize
00:06:29 Riding upon a semiplastic layer
00:06:33 the ocean floors and continents
00:06:36 or lithosphere are in continuing motion
00:06:41 Through the continents seem
00:06:44 they move an inch or more each year
00:06:48 The friction occurring along the
00:06:51 is often marked by earthquakes
00:06:53 and volcanic eruption
00:06:56 Sometimes, as in California's San
00:06:59 the opposing plates grind against
00:07:03 or lateral motion called translation
00:07:07 It is when a section of the fault
00:07:11 then abruptly releases
00:07:21 In other areas such as Japan
00:07:23 in a movement known as subduction
00:07:25 the edge of one crustal plate slowly
00:07:30 causing volcanic activity and tremors
00:07:38 Along the 46,000 mile Mid
00:07:41 in an action called spreading
00:07:44 or magma, emerges through fissures
00:07:48 soon congealing in new submerged crust
00:07:51 Sometimes, as in Iceland
00:07:53 and its offshore islands of Surtsey
00:07:56 the action has created
00:08:11 Barely two hundred miles south
00:08:13 on the fiery seam still building
00:08:17 Heimaey is accustomed to change
00:08:25 Port or the fleet that fishes
00:08:29 its only town of Vestmannaeyjar
00:08:33 take its toll of men and ships
00:08:37 Hardy descendants of the Vikings
00:08:38 who colonized the island more
00:08:42 its people long have learned to
00:08:45 to meet risk and hazard
00:08:58 Each summer
00:09:01 the entire population moves
00:09:04 on a three-day community holiday
00:09:07 It is a gathering that harks
00:09:11 when villagers assembled to
00:09:14 by which they lived
00:09:18 On the grassy floor of an
00:09:21 they build a tent city where the
00:09:25 each other in a quite different setting
00:09:39 Side by side, they celebrate
00:09:43 home rule
00:09:44 won from Denmark more than a century ago
00:09:47 the inheritance of their Viking past
00:09:50 their survival of dangers
00:09:52 that sometimes rise from
00:10:05 At midnight
00:10:06 young men set fire to a great wooden
00:10:11 As the flames flare against the dark
00:10:14 they summon varied emotions
00:10:25 To their Nordic forefathers fire
00:10:30 It was a symbol of life, of rebirth
00:10:33 But the people of Heimaey
00:10:36 that it also can bring destruction
00:10:48 In the winter darkness of
00:10:53 Just beyond the town's edge a fissure
00:10:56 abruptly spewing molten lava and
00:11:01 Roused from their beds
00:11:04 most of the population was evacuated
00:11:08 but volunteers would fight a five-month
00:11:13 now called Eldfell, "Fire Mountain."
00:11:22 Within a week Eldfell
00:11:25 smoldering cone six hundred
00:11:28 and covered the town in ash
00:11:30 More than a hundred buildings
00:11:33 or crushed under the advancing wall
00:11:46 In early February the lava threatened
00:11:51 Desperately, emergency teams fought
00:11:55 by hardening the lava
00:11:56 with great streams of cold seawater
00:12:04 At last, by heroic effort
00:12:08 But as the eruption continued
00:12:12 the lava would add almost one
00:12:16 while much of the town lay buried
00:12:26 It would take years to dig out
00:12:29 But at last the precincts of the
00:12:33 Elsewhere in Iceland life goes on
00:12:36 Under the shadows of the volcanoes
00:12:38 that remain a perpetual enigma
00:12:40 farmers gather crops, prepare
00:12:44 They are doing more
00:12:46 Boldly, Icelanders are making use of
00:12:52 In the north of the mainland
00:12:55 they are attempting to harness the
00:12:59 to power homes and
00:13:14 Recent eruptions have reminded
00:13:19 of the powers they are trying
00:13:22 With Dr. Haraldur Sigurdsson
00:13:24 vulcanologist from the University
00:13:26 Dr. Ballard visits a site where
00:13:29 has threatened a newly-built
00:13:40 "There's the power plant below
00:13:42 and if you look over this way..."
00:13:43 "Yeah. You can see the recent flows."
00:13:45 "The entire caldera, recent lavas..."
00:13:47 "Now the flows that were what
00:13:49 earlier this year, are down there?"
00:13:51 "Yes. And you can see the steam
00:13:54 that's been erupting during the
00:13:56 and the black lava flows that have
00:13:59 "So if, let's say, there were another
00:14:03 where we see the fissure opening up
00:14:06 the lava could just come down
00:14:08 and go right around the corner
00:14:13 Icelanders invested in the
00:14:16 because the field had lain dormant
00:14:21 Begun in 1975 as an alternative
00:14:25 the plant was almost immediately
00:14:28 by a series of violent eruptions
00:14:30 that brought the lava flow within
00:14:39 Trying to discern a possible
00:14:44 scientists keep watch on the plant
00:14:46 and the surrounding area
00:14:49 Here one of the monitoring
00:14:51 for any ground tilt

00:15:26 the steaming crest of the Mid-Ocean
00:15:31 Here Ballard and Sigurdsson visit
00:15:35 flow that is still cooling
00:15:51 "We're in the fissure that erupted
00:15:56 "So everything we are walking on
00:15:59 "That's right. And it's still
00:16:01 That's why it's still like a sauna bath."
00:16:04 "It's about as fresh as you can get
00:16:06 "Yes. Let's take a look around here."
00:16:10 "Now, if you can sit without
00:16:18 It's even warm
00:16:23 Now, I understand that when the
00:16:28 a tourist from Denmark
00:16:31 where the fissure opened up and was..."
00:16:33 "Quite close to the area
00:16:39 and rifted apart and the
00:16:43 "So he just took off."
00:16:46 "Actually, I understand the lava
00:16:50 "How fast?"
00:16:51 "Up to ten meters per second."
00:16:52 "So you'd have to be a... Let's see
00:16:55 the world's record for
00:16:58 "9.8."
00:16:59 "So it's running about as fast as
00:17:03 Hope the Dane was a fast runner."
00:17:05 "He was. He got away. So far there
00:17:09 "Before this took place
00:17:11 this area had been quiet for a long
00:17:13 This is why they thought it was safe
00:17:16 "This area has been without volcanic
00:17:21 And therefore, there was
00:17:25 that there wasn't an imminent danger
00:17:27 and it was a worthwhile risk to
00:17:31 of a geothermal power station
00:17:35 "And they've invested what?"
00:17:37 "Oh, probably about 60 million dollars"
00:17:40 "So 60 million dollars is
00:17:44 if another major eruption occurs here
00:17:46 and this time it does go over
00:17:48 that pass and down into the basin?"
00:17:50 "Well, that's always a possibility
00:17:52 But in Iceland there is...
00:17:55 where you have to live with
00:18:12 In patient calm, Icelanders
00:18:15 has imposed upon them
00:18:18 the sweeping storms, the hidden

00:18:29 who has built the very island on
00:18:31 they use his heat to warm their
00:18:35 even their indoor gardens a kind
00:18:38 for the risks they philosophically endure
00:18:45 In winter darkness they take
00:18:49 Warmed by the hidden furnace of
00:18:53 vegetables ripen in the arctic cold
00:18:58 In the volcano's fiery breath
00:19:13 Yet the risk remains
00:19:15 Hardly a year after eruptions
00:19:19 Sigurdsson returned to Krafla
00:19:21 as the restless giant stirred
00:19:25 Once more the lava flow approached
00:19:28 within one-and-a-half miles of
00:19:50 Though the fiery fountains
00:19:53 the eruption raised the ground
00:19:57 for future lava flows to travel
00:20:15 For the present the Krafla
00:20:18 But Icelanders know that eventually
00:20:23 of living on the edge of creation
00:20:39 Sometimes the action of the
00:20:42 brings surprisingly opposite effects
00:20:45 In Iceland its slow spreading
00:20:49 has created the great island on
00:20:53 Far southeastward
00:20:55 along the nearly 3,000-mile furrow
00:20:59 the spreading action is slowly
00:21:01 but inexorably opening the heart
00:21:06 In measurable time to come
00:21:08 eastern Africa will be detached
00:21:12 and this dusty desert landscape

00:21:39 an inland extension of the Gulf
00:21:42 the sea is temporarily delayed
00:21:44 by a narrow barrier of small volcanic
00:21:55 But as magma seeps through
00:21:58 and the seven-mile rift widens
00:22:01 the sea inevitably will pour
00:22:11 Already seawater from

00:22:36 Ballard descend into a recently
00:22:39 which a small flow of seawater
00:22:48 "So this is the sea coming in, right?"
00:22:51 "Yes, by a system of fissures."
00:22:56 "This is where the water
00:22:57 that we see on the other side
00:22:59 going into Lake Assal originates from?"
00:23:02 "Yes."
00:23:03 "So it comes in from the sea..."
00:23:05 "...from the sea and crosses the rift
00:23:09 by the fissures inside the mountain..."
00:23:13 "...and out the other side."
00:23:15 "Yes."
00:23:15 "Now, was this fissure
00:23:18 "Yes, yes."
00:23:19 "It just widened?"
00:23:21 "Just widened."
00:23:22 "Because a lot of these rocks
00:23:25 as if they're ready to come down."
00:23:27 "And the car here - just here..."
00:23:31 "Yeah, well, we should move the car."
00:23:40 "So we go like this."
00:23:43 "So we'll go across the..."
00:23:45 "Not across exactly like this. No."
00:23:47 "We go across this area, right?
00:23:49 Now how long will it take us to
00:23:52 If we went from here all
00:23:55 went across that flat
00:23:57 how long would it take to get there?"
00:24:00 "Maybe six hours."
00:24:02 "Six hours."
00:24:03 Terrible road. Six, six and a half."

00:24:29 near the shore of Lake Assal."
00:24:31 "The ocean is only six miles away
00:24:34 If it weren't for these young lava
00:24:37 I'd be under water right now
00:24:38 In fact, the ocean is
00:24:40 As rifting develops in the valley
00:24:42 these deep fissures start to form
00:24:45 This lets water travel beneath
00:24:47 through the fissures
00:24:48 and it can enter Lake Assal

00:25:50 in a massive subduction zone
00:25:54 In the deep ocean trenches off Japan
00:25:56 the aging plates plunge back into
00:26:00 causing powerful disturbances
00:26:02 The mists here are dragon's breath

00:26:51 memory and reality are like
00:26:54 of an earthquake fault
00:26:56 Here survivors come to witness
00:27:01 search again for faces that exist
00:27:09 Just before noon on Saturday

00:27:41 only to meet head on in midspan
00:27:45 Surrounded by walls of fire
00:27:48 the fleeing mass was locked
00:27:52 Next day two-thirds of Tokyo lay

00:29:35 have learned the precise steps

00:29:45 then take up their earthquake kits
00:29:47 and march off to join

00:31:20 against the North American plate
00:31:23 building stress, then suddenly

00:31:34 crossing the Carrizo Plain near
00:31:36 or pleasantly disguised

00:33:24 struck the San Fernando Valley
00:33:27 Twisting railroad tracks
00:33:30 shattering highway overpasses
00:33:33 it strewed disaster across
00:33:35 as if by an angry giant's hand
00:33:39 Like a silent accomplice
00:33:40 flames leaped through the wreckage
00:33:43 Great hospitals and other
00:33:47 Everywhere the quake trapped
00:33:50 When it had passed, the city counted
00:33:56 500 million dollars
00:34:00 Because the water behind a weakened
00:34:03 thousands of lives were saved
00:34:05 which otherwise might
00:34:11 In it's aftermath alarmed public
00:34:14 expanded their earthquake
00:34:17 Today not only standard
00:34:20 but a wide array of new
00:34:22 to monitor California's
00:34:26 Using laser beams and radio waves
00:34:28 from remote stars
00:34:29 scientists can measure the state
00:34:33 or plate movements as small
00:34:40 Along the San Andreas a network
00:34:43 reports local changes in the release
00:34:48 sudden drops in the water level
00:34:51 variations in gravity or the
00:34:55 Other meters detect the slightest
00:35:00 measure strain in a locked section
00:35:07 the state of California also
00:35:10 above which 24 million
00:35:18 From hundreds of
00:35:20 across the length of the state
00:35:22 continuous reports flow into
00:35:26 for the southern and the
00:35:34 At the United States Geological
00:35:37 widely diverse in formation
00:35:41 and condensed to provide a summary
00:35:45 during each passing month
00:35:47 Like scholars trying to break
00:35:50 or decipher a lost language
00:35:52 scientists are trying to discern
00:35:57 in all the signals sent
00:36:04 Though the San Andreas remains
00:36:06 a silent threat of havoc to come
00:36:09 sophisticated technology is
00:36:12 when man may be able to
00:36:15 with reasonable accuracy
00:36:18 Scientists know
00:36:19 that in prediction lies a major
00:36:27 Using an instrument no more
00:36:31 one young geologist
00:36:32 from the California Institute of
00:36:35 that the key to the future may lie
00:36:38 At excavations along the fault at
00:36:42 Dr. Kerry Sieh has revealed
00:36:45 of California quakes hundreds
00:36:48 before any recorded history
00:36:52 "We are on the main trace of the
00:36:54 And the layer that I just scraped
00:36:58 has been radiocarbon dated
00:37:02 The layer right
00:37:03 which has the beautiful orange
00:37:08 and here has a radiocarbon date near
00:37:13 or about the time Michelangelo was
00:37:18 This layer dates from about the birth
00:37:23 and this layer about right here
00:37:27 at the time of the 1857 earthquake
00:37:30 "Now, this is the main trace of
00:37:34 through these layers up though to
00:37:38 "Here's the 1353 A.D. layer broken
00:37:41 by the fault trace coming up
00:37:43 through the 1560 A.D. layer here
00:37:46 So here we have the Pacific Plate
00:37:49 and here we have the
00:37:51 broken only by this very narrow trace,
00:37:54 of the San Andreas Fault."
00:37:55 "And it continues on up
00:37:58 and stopping at this level
00:38:02 In 1857 there occurred the great
00:38:06 which was the last great earthquake
00:38:09 in the southern part of the state."
00:38:10 "Elsewhere at this site
00:38:12 we have exposures a total of 11
00:38:15 and the great Fort Tejon earthquake
00:38:19 The radiocarbon dates show
00:38:21 that the earthquakes occur
00:38:24 they occur about every 145 years
00:38:27 It's been 125 years since the great
00:38:31 The chances are really quite
00:38:34 within our lifetime
00:38:35 we're going to see another great
00:38:41 "Give me the number of dead you
00:38:44 that you are estimating
00:38:46 and I will try to work it out on
00:38:48 "Estimates of injured range
00:38:53 with an unknown number trapped in
00:38:57 At this time the numbers of dead may
00:39:02 To train disaster agencies
00:39:04 and to alert the public the state's
00:39:06 Emergency Services stages
00:39:10 "I would like to clarify what's
00:39:13 of a radioactive release problem
00:39:17 Alex Cunninham
00:39:19 director of the California Office
00:39:23 "The scenario for this exercise is
00:39:25 that an earthquake occurred
00:39:30 actually about 30 miles northwest
00:39:33 along the San Andreas Fault
00:39:36 Its magnitude, for exercise
00:39:46 "And believe me
00:39:48 at this level on
00:39:50 And I recommend strongly now
00:39:52 I can't handle a delicate issue
00:39:55 I recommend very strongly that if
00:39:57 that you are going to have to come
00:40:00 "We need to have an update
00:40:02 as of this time on the number of
00:40:06 "All the hospital beds in northern
00:40:10 Southern county looks like
00:40:13 But the Needs Assessment Team
00:40:14 back half an hour and will give us
00:40:16 "Hold on a second. We got to
00:40:20 "The State of California is
00:40:24 handle a moderate earthquake
00:40:26 And the citizens who have been
00:40:28 are reasonably well prepared
00:40:30 But when we talk about a
00:40:32 something in the area of an 8
00:40:34 or an 8.3 no level of government
00:40:36 and particularly the
00:40:38 are prepared for such an event
00:40:41 It's no longer a question of if
00:40:44 It's simply a matter of when
00:40:46 Scientists are telling us
00:40:47 because of recent seismic activity
00:40:49 and other phenomena
00:40:51 that the great earthquake will strike
00:40:55 some time in the next 30 years
00:40:58 Unfortunately, many people say well
00:40:59 if it's 30 years away
00:41:00 we don't have to worry about it
00:41:02 It's not 30 years away
00:41:03 It could happen tomorrow
00:41:05 it could happen next month
00:41:07 But sometime in the next 30 years
00:41:09 we're going to have it
00:41:10 and people damn well better
00:41:14 Distantly aware of
00:41:17 most Los Angeles residents remain
00:41:20 and traffic jams of daily life
00:41:23 Too few know the mathematics of terror
00:41:26 At the time of the 1857 quake 11,000
00:41:32 Today there are more than seven million
00:41:36 Many remember the impact of
00:41:39 But the 8.3 earthquake
00:41:41 which scientists now predict
00:41:43 will be a shock 800 times as strong
00:41:48 a natural disaster
00:41:58 Thirty-five hundred years ago
00:42:03 these ruins too held a civilization
00:42:07 Here, long before the Parthenon
00:42:10 the maritime community of Akrotiri
00:42:13 that rivaled the splendors of
00:42:18 In frescoes artists painted
00:42:20 the sunlit landscapes of man
00:42:23 the years in Eden when the Earth
00:42:30 Upon the walls were mirrored
00:42:32 and pleasures of a small world
00:42:34 in which the simplest acts of
00:42:38 and even the gods often behaved
00:42:43 Over the wide sea, returning seamen
00:42:48 and creatures from the shadowy lands beyond
00:42:51 told of odysseys across
00:42:56 Now they are gone
00:42:58 abruptly vanished in
00:43:01 All that remain are a half-excavated
00:43:06 a few amphoras in orderly array
00:43:08 life and death filed on
00:43:14 One of the scientists trying to
00:43:18 Dr. Christos Doumas of the University
00:43:23 through the remains of a city
00:43:24 that died thirty-five centuries ago
00:43:28 "This is an ancient street leading
00:43:31 flanked on the left by
00:43:35 and on the right by the West House."
00:43:38 "Now here's where you
00:43:40 "Yes, we found frescoes
00:43:44 that we are discovering here a very
00:43:50 of the Bronze Age."
00:43:52 "The houses are individual
00:43:56 There are several stories
00:43:58 and we have indoor plumbing
00:44:02 with the drainage system
00:44:04 "So you had a society of individual
00:44:11 "Yes. And every house was
00:44:21 "And here we can see how
00:44:25 The basement, as in
00:44:27 many of the houses
00:44:31 goods a variety of crops like barley
00:44:38 lentils, various nuts like almonds."
00:44:43 "So they had a pretty good diet
00:44:45 I mean it was varied."
00:44:46 "Yes. And they were consuming
00:44:48 because we found shells of
00:44:51 and remains of dried fish
00:44:57 "The city was captured by
00:45:01 this staircase shows
00:45:02 that it was broken before the
00:45:05 "So this probably caused
00:45:08 "Yes. It was a warning
00:45:10 "And then after the earthquake
00:45:12 the major eruption occurred."
00:45:15 "Yes. It destroyed almost everything
00:45:18 as you sea and then the site was
00:45:26 Before the great warning tremors
00:45:28 Akrotiri lay on the flank of a
00:45:32 unaware that miles below
00:45:34 the Earth's crust was in movement
00:45:45 Soon after the quake
00:45:46 the island exploded in one of historical
00:45:51 Suddenly a mountain had disappeared
00:45:54 its walls collapsed into a volcanic
00:45:58 by the inrushing sea
00:46:05 A vast searing cloud of pumice and
00:46:10 and surged over the Mediterranean
00:46:12 with an impact on history that
00:46:18 "We're inside the caldera
00:46:20 Behind me are the layered walls
00:46:22 which record its long history
00:46:24 The black layers are basaltic
00:46:26 the red ones a tephra ejected
00:46:30 "These prehistoric layers once
00:46:32 formed a great volcano over
00:46:36 About 3,500 years ago
00:46:39 the entire volcano erupted destroying
00:46:44 At the top today you can see a
00:46:47 and ash which records
00:46:50 That layer is over 100 feet thick."
00:47:00 Human beings still cling to the
00:47:03 that now surrounds emptiness
00:47:05 Today several thousand islanders
00:47:09 and fish or search for sponges
00:47:14 Steep paths link them with the ports
00:47:18 much of their fresh water
00:47:19 and occasional visitors arrive
00:47:26 Today the centers of Western
00:47:29 have moved far beyond Santorini
00:47:31 Insulated from the rumors and
00:47:35 it has settled into the ways of
00:47:51 Upon the cliffs workmen build
00:47:53 and repair structures using
00:47:56 and pumice of the explosion
00:47:57 that once destroyed their island
00:48:00 In the fields around them
00:48:02 farmers tend vineyards
00:48:03 and reap grain planted
00:48:08 The pumice is even sold for profit
00:48:10 was once exported for the
00:48:13 more than a century ago
00:48:23 Intermittently strong tremors still
00:48:27 but the widows of Santorini remain
00:48:32 by which life endures
00:48:35 Beneath them one plate slides
00:48:37 under another in endless movement
00:48:40 even the gods may change
00:48:42 but prayer remains a step
00:48:45 for reassurance and certainty
00:49:05 On Good Friday
00:49:06 worshippers are surrounded by frescoes
00:49:08 that describe not the joys of life
00:49:15 Yet for the devout islanders
00:49:17 faith holds a triumphant hope
00:49:20 Out of death's darkness life returns
00:49:23 a flame passed from candle to candle
00:49:32 In the ritual of twenty centuries
00:49:34 again find a ancient recognition
00:49:37 In the Easter story of resurrection
00:49:40 they tell their own
00:49:55 After the resurrection joy
00:49:58 the breaking of eggs to release
00:50:10 Across the island
00:50:11 after forty days of fasting
00:50:13 the villagers feast and dance
00:50:41 The world has changed many time
00:50:44 since this woman lived in Santorini
00:50:46 Her gods have vanished
00:50:49 The streets on which she walked now
00:50:54 Yet in these dancing rhythms of life
00:50:57 she might hear echoes of another time
00:51:00 the refrains of home
00:51:04 Imperceptible to living generations
00:51:07 the change goes on
00:51:09 toward a future
00:51:12 already have begun to outline
00:51:17 By its present drift
00:51:19 Africa, in its clockwise movement
00:51:22 will close the Mediterranean
00:51:23 and collide with southern Europe
00:51:26 raising great new mountain ranges
00:51:41 In Africa itself the sea at last will
00:51:46 isolate eastern Africa
00:51:49 invade a domain once held by
00:51:58 In the Americas, as elsewhere
00:52:00 life will be radically altered
00:52:05 Mecca for millions of fugitives
00:52:09 Los Angeles may have to doctor its
00:52:14 Set at the edge of the Pacific Plate
00:52:17 it is moving relentlessly
00:52:20 at the rapid of two or three
00:52:24 Ten million years from now
00:52:26 San Francisco will find
00:52:27 that for a time its scorned southern
00:52:40 New York may become part of a
00:52:44 as the expanding Atlantic floor
00:52:54 Compared to Earth's history
00:52:56 man's tenure has be dazzling
00:52:59 In ten thousand years he has
00:53:03 built cathedrals, invented the means
00:53:08 His computers can project
00:53:11 of continents 200 million years
00:53:15 But where man will be none can predict
