Hi Mike, Chris, List,
Personally I think Chris hit the nail on the head when he said "But
realistically, a 10 meter object that was moving at hypervelocity all the
way to the sea, and near shore, would have produced a massive fireball,
rivaling the Sun, would have left a long lasting dust debris train, and
would have been witnessed by thousands of people."
I'd assume that a large event like that would have also shown up all all
sorts of monitoring points from satellites and/or radar to seismic stations
too.
Cheers,
Jeff

Hi Chris and List,
I agree. As the eyewitness account reads, it's impossible for such an
object to create a large wave. However, if the account was in error
about the size of the object, then perhaps it becomes a little more
possible.
What about the velocity of the object? Let us suppose that it
retained a good bit of it's cosmic velocity when it struck the water.
Would an object about 10-30 feet in diameter, travelling at a high
rate of speed (say, 1km per second), generate a large wave? I would
think that the speed at impact would play a role in the effects once
it hit the water.
I think the underwater landslide theory is more plausible. I was just
surprised to see an account about a "meteorite" in this story.
Best regards,
MikeG

A meteorite that was 1-3 meters across would make a splash, that's all. A
couple of hundred meters away and there'd be virtually no energy left.
There's almost no possibility of such an object creating a wave like the
one
you describe (a tsunami, not a rogue wave).

Subject: [meteorite-list] Meteorite Caused the Daytona Beach Rogue Wave
in1992?
Hi List,
All of this talk about the tsunami in Japan reminded me of an event
that happened here in Florida in 1992, that may have a meteorite
connection.
On July 3rd, 1992, a 20-foot rogue wave appeared out of nowhere (calm
weather) and washed ashore on Daytona Beach, damaging many vehicles
parked along the beach and causing scores of minor injuries -
thankfully there were no fatalities. This event was big news down
here at the time, but has since faded into obscurity.
I did some digging on the event, to satisfy my own curiosity and I
came across an account that includes a possible meteorite fall.
Here is a quote from an eyewitness who was a boater that was offshore
at the time -
"...the boater came forward with the information that, shortly before
the time of the wave, he was in his boat about eight miles offshore.
He watched as a distant object approached across the sky toward the
ocean at a high rate of speed, and crossed the bow of his boat at an
angle with a "whoosh" (his word). Shortly after, a giant swell made
his 41-foot sailboat handle like a large surfboard. Various news
sources state that the meteorite, as it is now being called, was
anywhere from a meter to 10 feet across. The boater who wished to
remain anonymous, gave the professors enough information so that they
are hoping that the Navy will retrieve the object, which is presumed
to be lying in about 70 feet of water off the Daytona Beach coastline,
with plenty of coordinates for locating it."
(source : http://www.science-frontiers.com/sf084/sf084g12.htm )
Does anyone remember this "meteorite" event? And, did anyone look for
the object? I know 70-feet of water is not exactly prime
meteorite-hunting territory, but one has to wonder what happened, in
light of the eyewitness account.
Best regards,
MikeG
