  1. All video consists of a series of photos strung together. For movies and TV, the frame rate (=number of images per second) is between 24 and 60; 24 frames per second is the minimum the human eye needs to perceive smooth motion. These weather satellites take one photo every 10 minutes. When you string these together (as Scott did for this video), you get a time lapse video, not an animation.

  2. This volcano has had at least 5 eruptions in the last 10 years. It doesn't need our help.
    8
  3. Resolution on these images is 0.5 km/pixel, and the images are 10 minutes apart. Those are clouds, from a smaller eruption before the main one.
    7
  4.  @Stellaria2025  That's not a missile entering the water, that's a cloud exiting the water from smaller-scale volcanic activity before the main eruption.

  5. That's not a projectile. Resolution on these images is 0.5 km/pixel. Those are clouds, from a smaller eruption before the main one.

  6. DISCOVR images of Earth, incl Moon and Earth in one shot: @ and Earth from the moon: @ Face it, these are all true images. We don't need CGI to make these images, we have satellites. Every 10 minutes, this satellite takes an image of the entire hemisphere, with all of the clouds shown correctly (the only way to get an accurate weather forecast). There is no way to get all this data without satellites.
    7
  7. this video does not show details smaller than 500 meters. No missile is that large. All we have is one frame showing a cloud that's 1-2 km wide.

  10. Earth is a sphere. It has a curvature of 8 cm per km. This can easily be verified through many different methods. You need to stop trolling and face the truth.
    6
  11. There's an overlay on the images that makes it easier to recognize regions. That's an optional addition, if you go to the GOES site you can also get them without. Protip: when you don't understand what you're looking at, "it's fake" is unlikely to be the correct response.

  12.  @mynameis.5480  Digging a tunnel in Europe doesn't cause volcanic eruptions in Tonga.

  13. The earth looks a bit different than you're used to because the imaging system uses 2 color channels instead of 3 (RGB). And some of the footage uses an additional infrared channel).

  16.  @m0uz  Sure you can verify this. One method: On a piece of level ground (a salt lake is good for this), set up a scope with crosshairs, make sure it's level. Measure the height of the crosshairs above ground. Get an assistant to stand 500 meters from the scope with a measuring tape. Through the scope, read the measuring tape. Repeat this at 1000 meters. The reading at the 500 meter point will be lower than the reading at 0 and 1000 meters. Another method: we have a horizon. When you get farther away from an object, it will disappear below the horizon. This is correctly predicted by the 'Earth is a sphere' hypothesis, and it disproves the 'Earth is flat' hypothesis. The 'Earth is flat' hypothesis is full of holes and cannot be maintained by anyone who applies scientific rigor and logic.

  18. Those 2 satellites have been in that position for years, and they cover the entire hemisphere.
    5
  19. Sure, that's how I would start a war. Nuke an uninhabited island near the big important, dangerous country of... Tonga. :facepalm

  20.  @sheshanamahmood3073  These videos are made from individual photos that were taken 10 minutes apart. A missile would be visible in 1 frame only, making it impossible to see the missile move. Combine that with the resolution, and the conclusion must be that you're seeing something much larger than any missile. The volcano was active for several hours before the big explosion, so it's likely you'r'e seeing some venting from the volcano.
    5
  21. These satellites image the entire hemisphere every 10 minutes. You'd need 500,000 radar stations spread over the entire world to replicate that with ground-based photos. Show me where the 350,000 radar ships were built.
    5
  22. Tsunami all over the world, Tonga inundated and covered in ash, people dead, and you have the gall to call this fake?
    5
  23. Balloons have a maximum altitude of about 50 km. This footage was taken from 36,000 km. How many balloons does it take to photograph Earth's entire surface every 10 minutes?
    4
  24.  @jackyjax5513  The Bible is not a scientific treatise, it explains the world in words understandable by its audience. We've known for 2500 years Earth isn't flat.
    4
  25.  dolimi jotoo  That's not entering the water, that's a cloud exiting the water from smaller-scale volcanic activity before the main eruption.
    4
  26. this video has a resolution of 500 meters/pixel, and it consists of images taken 10 minutes apart. So you're looking at a cloud that's 1-2 km wide.
    4
  27.  @user-pf5xq3lq8i  no, correlation is not a link. That's what "correlation is not causation" means. You can't just take two events that happen at the same time and assume they must be related.
    4
  28. Earth's deviation from round is 23 km, on a radius of 6370 km. That's too small to be visible with the naked eye on the downscaled image on most monitors. If you download a full-resolution image (10k x 10k pixels) and measure the image in an image editor, the oblateness will show up.
    4
  29. the smallest details visible in the video are 500x500 meters. What you're looking at is clouds, not a missile.
    4
  30. this video does not show details smaller than 500 meters. No missile is that large. All we have is one frame showing a cloud that's 1-2 km wide.
    4
  31. Any large explosion causes a mushroom cloud. Volcanic eruptions have been recorded thousands of years back, long before we developed nuclear weapons.
    4
  32. this video does not show details smaller than 500 meters. No missile is that large. All we have is one frame showing a cloud that's 1-2 km wide.
    4
  33. Yes. Nuclear explosions look very different, and have a different seismic signature.
    4
  34.  @Stellaria2025  Again, this video does not show details smaller than 500 meters. No missile is that large. All we have is one frame showing a cloud that's 1-2 km wide.

  35. The images from GOES and Himawari are publicly available.
    3
  36. Current estimate is VEI 5.
    3
  37.  @trendynow1369  Only the highest mountains are visible from 40+ miles away. Smaller objects are hidden by Earth's curvature at shorter distances. You can verify this e.g. in a sea port: as a ship moves out of the port, less and less of the vessel is visible as it gets farther away.
    3
  38. nuclear explosions do not provide 9-hour ash fountains, the updraft stops within 15 minutes.
    3
  39. They take photos every 10 minutes, with clouds in the correct place. How many aircraft does it take to photograph the entire globe at 10-minute intervals?
    3
  40. This is a geostationary satellite, at an altitude of 36,000 km. Its resolution is 0.5 km/pixel, so cities will show up but you can't see individual buildings. On a sphere's surface, the force of gravity is a vector that points towards the center of the sphere. So yes, those people really are upside down compared to folks in the Northern hemisphere.
    3
  41.  @the_flat_earth_warriorz  Science gives us a complete and consistent explanation of how people can live on a globe. Every argument in favor of a flat Earth falls apart if you start examining it.

  42. this video does not show details smaller than 500 meters. No missile is that large. All we have is one frame showing a cloud that's 1-2 km wide.
    3
  43. 'bendy oceans' are real. On a sphere's surface, the force of gravity is a vector that points towards the center of the sphere. This force acts on water, so water will distribute itself until every point of its surface is at an equal distance from earth's center.  The thermosphere is hot, but its density is very low. So it can only transfer a small amount of energy, not enough to heat up a rocket. I could go on, but these two should give you some food for thought.
    3
  44.  @danielorourke2677  Earth is not flat. It has a curvature of about 8 cm per km. You can easily measure this for yourself.
    3
  45.  @danielorourke2677  Let's use some data from this eruption to prove the Earth is not flat. The pressure wave from the explosion traveled around the world, twice. On a flat Earth, you can't do that.
    3
  46.  @user-pf5xq3lq8i  Interesting, and I stand corrected. However, that paper shows the frequency of earthquakes increases when the proton flux is high. You're talking about a solar minimum, and the proton flux is low during a minimum.

  47. BTC is down 50% from its peak. And it's so energy-inefficient you can do 1,000,000 credit card transaction for the cost of one Bitcoin transfer. Lovely currency you have there.
    3
  48. No, real images. Get your head out of the sand.
    3
  49. Right, people dead, explosion heard thousands of km away, shockwave measurable on the other side of the planet, must be fake. Think before you post.
    3
  50. the images were taken 10 minutes apart, each image is about 5 frames of the video.
    3
  51. You're not accounting for gravity. On a sphere's surface, the force of gravity is a vector that points towards the center of the sphere. This force acts on water, so water will distribute itself until every point of its surface is at an equal distance from earth's center. That's the level it finds.

  52. A nuclear explosion has a distinctive seismic signature that can be detected on the other side of the world. That signature has not been found in this event.
    3
  53. Yes, 36,000 km. Why would you not consider that to be in space?
    2
  54.  @mikeybonilla2268  A nuclear explosion has a distinctive seismic signature that can be detected on the other side of the world. That signature has not been found in this event.
    2
  55. about 1000. Current estimate is 10 megatons.
    2
  56.  @Blamejames78  about 1 in 40 years on average, the last one was Mt Pinatubo in 1991.
    2
  57.  @Blamejames78  No worries, volcanoes are a big and complicated subject, we're all learning as we go along.
    2
  58. no, the CO2 output from this volcano is about what we produce in 1 day. This eruption is not large enough to affect our climate.
    2
  59. Earth is a sphere. It has a curvature of 8 cm per km. This can easily be verified in many ways.
    2
  60. Volcanic eruptions produce far more SO2 than CO2. SO2 produces a cooling effect; the Pinatubo eruption lowered the average temperature by 0.6 ºC for 2 years. This eruption is much smaller, so the current estimate is a temperature change of -0.01 ºC for this year.
    2
  61. Volcanoes produce about 1% of the CO2 emissions caused by humans. This isn't a guess, we can measure it.
    2
  62.  @tallcedars2310  It depends. On this occasion, a large volume of magma was exposed to ocean water at once. This created a steam explosion. Other volcanoes build up so much pressure that when the magma breaks through the rock plug on top of it, it's with explosive force. The Krakatoa eruption could be heard from thousands of km away.
    2
  63.  @tallcedars2310  Krakatoa erupted in 1883, it's one of the biggest eruptions in history. So not news that you missed :) When you have a large volume of water that abruptly gets converted to steam, it's considered an explosion and will create a shockwave.
    2
  64. nope, actual photos from actual satellites.
    2
  65. Yes. Eruptions go on for hours, as can be clearly seen in this video. In an atom bomb explosion the mushroom cloud quickly starts to dissipate, it doesn't keep growing for hours.
    2
  66. No. Images taken after the eruption show that the two islands on the edge of the caldera are now smaller.
    2
  67. It's a volcano. A nuclear bomb looks very different.
    2
  68. That location is a known volcano that has erupted several times the last few years. ICBM warheads must be detonated before impact: the impact will destroy them. So you can't launch a missile and detonate it weeks later.
    2
  69.  @user-pf5xq3lq8i  Take a look at figure 4 of the 2020 paper. This shows that earthquakes become more frequent when the proton density rises. It does not show a second peak at low proton densities. So this paper does not predict an increase in earthquakes at a solar minimum.
    2
  70. Yes, this is an image from space. It looks a bit different to what you're used to, this is a scientific camera, not a cellphone. That means the colors are a bit different. Next time you see something you don't understand, don't be so quick to assume it must be fake.
    2
  71. Those satellites are owned by NOAA and JAXA.
    2
  72. The main problem is scale. This explosion had the same power as 10 million tons of TNT. To block the volcano, you'd have to drill down (without causing an eruption) and circulate water to cool down the lava until it solidifies. That requires millions of tons of water, thousands of drill sites. And you have to keep doing this because Earth keeps heating the lava from below.
    2
  73. To do that, there has to be a ground station on Tonga. I don't know if that's the case. A ground station could easily have been damaged by the shockwave or tsunami.
    2
  74.  @peckop1793  GPS was designed to provide the US military with accurate navigation over hostile territory. You know, the kind of territory where you can't place navigation beacons and you can't rely on civilian beacons being available. They experimented with astronavigation: installing star trackers on aircraft to get position data. That turned out to be not reliable enough, so they went to the only method that would work: satellites in space, out of reach of any enemies.
    2
  75. Right. Whole islands devastated, people dead, tsunamis, pressure waves measured all around the world "all CGI". Are you really that stupid?
    2
  76. That's a water fountain from an earlier, small eruption. The resolution of these images is 0.5 km, a missile is far too small to show up.
    2
  77. no, this volcano produced as much as we do in 1 day.
    2
  78. This video does not show details smaller than 500 meters. No missile is that large. All we have is one frame showing a cloud that's 1-2 km wide.
    2
  79. A nuclear explosion has a distinctive seismic signature that can be detected on the other side of the world. That signature has not been found in this event. Also, if you're going to wipe out evidence of anything, you don't nuke an uninhabited island.
    2
  80. This eruption provides about as much CO2 as 1 day of human activity. Look at the data before making grand proclamations.
    2
  81. no, that's an earlier, smaller eruption. The resolution of these images is 0.5 km, a missile is far too small to show up.
    1
  82. this emitted about 1 day's worth of human emissions.
    1
  83.  @ED-988  no, in total.
    1
  84. Your 1 foot mineral blocks have been photographed from a low-altitude aircraft: the highest zoom levels of Google Earth aren't satellite imagery. This was seen from 36000 km away. Isn't it fascinating that we have the technology to photograph the entire hemisphere every 10 minutes?

  86.  @rushgush  We have known the world is a sphere for 2500 years: there are all kinds of measurements we can do on the ground to verify that. Balloons are limited by physics, the higher they get, the smaller their payload is. We have photos of Earth from space not just from NASA, but from dozens of space agencies all around the world. We have photos showing the curvature of Earth from high altitude from even more sources: an airplane or balloon at 10-15 km altitude is enough to make this curvature visible to the naked eye. And you haven't answered my question. How many balloons does it take to photograph all 510 million km2 of Earth's surface every 10 minutes? About 5 million. Show me the balloon bases where they can maintain, refuel and launch 5 million balloons every few days.

  87. Spy satellites have a resolution of about 30 cm/pixel. To be able to read fingerprints, you'd need a telescope mirror hundreds of meters across.
    1
  88. Climate impact from volcanoes is about 1% that of humans. Only the largest eruptions (Krakatoa) have a measurable impact on climate.
    1
  89. No, it was a volcano. The volcano in that area has erupted several times in the past few years.
    1
  90. No, that's a volcano. Nuclear bomb blasts don't keep generating ash clouds for several hours.
    1
  91.  Friendy Frienderson  these videos do not show details smaller than 500 meters. No missile is that large. All we have is one frame showing a cloud that's 1-2 km wide. Also, volcanic eruptions can be loud enough to be heard on the other side of the world.
    1
  92. I don't have to imagine, I can calculate. Earth's curvature is 8 cm per km, which can be easily measured if you're in the right place, but is too small to see with the naked eye at ground level. Dozens of satellites take photos of Earth every day: these weather satellites alone take compete-hemisphere pictures every 10 minutes.
    1
  93. That's a small eruption before the main one.
    1
  94. The eruption continues to generate steam and smoke after the shockwave.
    1
  95. no, it's a volcano. It's been active recently and it has erupted several times in the past few years.

  96. ​ Friendy Frienderson  Volcanic eruptions can produce explosion sounds. Krakatoa in 1883 could be heard thousands of km away.

  98. The last one this big was 40 years ago, Mt. St. Helens.
    1
  99. Krakatoa produced about 10 Gt of CO2. We produce 200 Gt per year at the moment.
    1
  100.  @Lion2Lamb247  nope. We knew about every one of his tests immediately. Nuclear bombs have a distinctive seismic signature very different from volcanic eruptions.
    1
  101. This released less CO2 than we do in 1 day.
    1
  102. An atomic bomb test is over in a few minutes, with the cloud staying in place for half an hour or so. This cloud keeps growing for hours. Not a bomb test, a volcano.
    1
  103. No. This was a VEI 5 earthquake. We've had VEI 7 (i.e. 100 times larger) without cracking the crust.
    1
  104. Rockets aren't large enough to show up in these images (resolution is 0.5 km/pixel). It looks more like a small eruption to me.
    1
  105. Pinatubo was a bit larger than this one though, VEI 6, while this is a 5 (i.e. a factor 10 smaller).
    1
  106. One spacecraft is operated by NOAA, the other by JAXA.
    1
  107. Correlation is not causation. No link between solar activity and volcanism has been found.
    1
  108. No, that fountain is a smaller eruption before the main one. The splash caused by a missile is far too small to be seen on these images.
    1
  109. That satellite is at an altitude of 36,000 km. You can calculate the minimum altitude needed to image a full hemisphere: that's about 12,000 km. Clearly, 36,000 km is high enough.
    1
  110. Satellites in orbit follow a path that's parallel to Earth's surface. So of course a rocket isn't launched straight up but in a curve. It doesn't come back down though, its altitude keeps increasing. To get into orbit, you need a lot of speed (8 km/s) so most of the rocket's thrust must be expended in the horizontal direction. This is obvious when you watch the uncut video of any rocket launch.
    1
  111. People are claiming that but don't have any evidence. This was a natural event.
    1
  112. no, that's an earlier, smaller eruption. Image resolution is 0.5 km/pixel, a missile wouldn't show up.
    1
  113.  @gotohell6814  the images are 10 minutes apart.
    1
  114.  @gotohell6814  You can use the . key to step through the video frame by frame.
    1
  115.  @gotohell6814  At 2 o'clock from the eruption? that looks like a smaller vent to me, with smoke going up. I've played with the footage a while and there's nothing that looks like a missile to me. Keep in mind this footage has a resolution of 0.5 km/pixel. Items as small as a missile don't show up.
    1
  116.  @gotohell6814  Sound travels at 300 m/s, so 200 km in 10 minutes.
    1
  117.  @gotohell6814  Shock waves move at the speed of sound.
    1
  118.  @gotohell6814  you're right, of course.
    1
  119.  @gotohell6814  No worries, I learned something today, and that's always good.
    1
  120. This one seems to be about 1/100 the size, so it won't be that severe.
    1
  121. no, that's a smaller burp before the main eruption. The photo resolution is far too low to image a bomb.
    1
  122. That's the same satellite that generates the data for your weather forecast every day.
    1
  123.  @mynameis.5480  When we look at the actual records, there's no increase in volcanic activity. There is a big increase in reporting: these days, people everywhere get notified about natural disasters happening on the other side of the planet within hours of the event. 30 years ago, that wasn't the case.
    1
  124.  @mynameis.5480  I prefer science over bullshit.
    1
  125.  @bufordmaddogtannen5164  no. The CO2 from this event is about what we produce in 1 day.

  126. Volcanic eruptions are difficult to predict.

  127. There have been several smaller eruptions recently.

  129. That's a small eruption before the main one. Remember, these are photos taken 10 minutes apart.
    1
  130. this eruption is too small to affect our climate.
    1
  131. I don't think so. At that stage, the tsunami would be a tiny ripple. Shock waves show up better in the atmosphere.
    1
  132. They have only been 'manipulated' in the sense that an overlay has been added to make it easier to identify regions. The original images without overlay are also available and have been used in the video as well.
    1
  133. Right, people dead, explosion heard thousands of km away, shockwave measurable on the other side of the planet, must be fake. Think before you post.
    1
  134. A nuclear bomb on a ballistic missile has to be detonated before it hits the water, the force of impact would destroy the bomb and make it impossible to detonate.
    1
  135. These are geostationary satellites. At an altitude of 36000 km, they complete one orbit in 24 hours, so they appear stationary above Earth. This is convenient for e.g. meteorology: you can take images from the same position every few minutes and see weather patterns develop. These images gover the entire hemisphere.
    1
  136. this eruption wasn't large enough to have that big an effect.
    1
  137. no, real photos from several different sources.
    1
  138. Mt. Pinatubo was a lot larger than this one.

  140. All large explosions produce similar-looking clouds. This was not nuke, it's a volcano. It has erupted several times in the past 10 years.
