Huge fireball explodes over Atlantic as meteor flies into Earth from space
Source: Independet (UK)
A huge fireball crashed into the Atlantic this week, unleashing the same amount of energy as the first atomic bomb, and barely anyone noticed.
A meteor flew into the atmosphere about 600 miles off the coast of Brazil. As it did so, it exploded in the air and unleashed a huge blaze in the Atlantic sky but nobody was really around to see it.
Even despite the huge power of the explosion, scientists said that the explosion would have caused few problems even if it happened near people.
...
The explosion was the most powerful since a fireball exploded over Chelyabinsk. That injured 1,6000 people when it exploded in February 2013.

(4,742 posts)Last night I was sleeping and had a dream I saw a huge meteor flying over. I pointed it out to the person I was talking to and rememebered thinking "GEe that thing is going to really blow or cause damage somewhere."
I don't believe in premonitions or anything but what a weird coincidence.

(101,321 posts)The Independent has just got it wrong when it says "this week". They quote Phil Plait, but his Slate column says it happened Feb 6th: http://www.slate.com/blogs/bad_astronomy/2016/02/20/fireball_over_atlantic_ocean_on_february_6_2016.html

somethin' in the air lately perhaps? damn those chemtrails.
oh oh.. now that word will probably flag the NSA's attention. whoops!

(41,832 posts)does anyone know if it generated a Tsunami? I am curious...
muriel_volestrangler
(101,321 posts)But I don't think an explosion at sea level would generate a true tsunami. From the point of an explosion, you'd get normal waves, radiating out as circles, and losing height as they go out. For instance:
...
A series of surface waves moved outwards from the center. The first wave was about 94 ft (29 m) high at 1,000 ft (300 m) from the center. Other waves followed, and at further distances some of these were higher than the first wave. For example, at 22,000 ft (6,700 m) from the center, the ninth wave was the highest at 6 ft (1.8 m).
...
The heights of surface waves generated by deep underwater explosions are greater because more energy is delivered to the water. During the Cold War, underwater explosions were thought to operate under the same principles as tsunamis, potentially increasing dramatically in height as they move over shallow water, and flooding the land beyond the shoreline.[6] Later research and analysis suggested that water waves generated by explosions were different from those generated by tsunamis and landslides. Méhauté et al. conclude in their 1996 overview Water Waves Generated by Underwater Explosion that the surface waves from even a very large offshore undersea explosion would expend most of their energy on the continental shelf, resulting in coastal flooding no worse than that from a bad storm.[1]

(101,321 posts)At 300m from the point an atomic bomb explodes, a 94ft wave is just one of many problems.

(22,670 posts)I hear that said all the time in stories or by scientists. I think it just looks like dust and gas from 4 trillion light years away. In my opinion, it's really rocks, boulders, mountain sized objects, and planets. When they say our part of the galaxy will be having one of these clouds of dust and gas pass through it, but then you see stuff like this, it makes you wonder.

(10,495 posts)Florida around 2 a.m. a few years ago. The road is lined with fairly tall pine trees which limits the view of the sky to a narrow band. Suddenly, a ball of fire the size of a big house arches across our vision heading into the Gulf of Mexico. We were so totally freaked out, but disappointed that we could not see the impact in the water. It was one of the most amazing natural phenomena I have ever witnessed!
