Have any calculations been made to try to predict what size of tsunami this kind of object would have produced? When you consider that a chunk of Hawaii falling into the ocean is suspected of triggering a "mega-tsunami" that deposited coral seafloor high on a cliff in Australia, I think this could have been much worse.
I would guess that some rogue waves are caused by distant meteor falls.
I would also be very interested in eyewitness reports of electrophonic sound PRIOR to the acoustic shock -- that is, during the brightest flaring of the fireball. This is a at-long-last well-established effect of plasma-generated radio noise coupling into near-observer physical objects and creating a hissing or whooshing sound. It occurs simo with the visual flares, seems to come from 'all around' [not from above], has been reported for centuries by some bright fireball witnesses and pooh-poohed by scientists until work by Colin Keay and others established its validity.
Jim, there were indeed plenty of such reports.
Today's article http://chelyabinsk.ru/text/newsline/625214.htmlis titled **Chelyabinsk Fireball turned out to be "sounding"**
there is no case in the entire recorded history of meteorite tsunami.

"… далекий звук возник еще до появления свечения - похожий на гул от самолета. Звук шел с той же стороны, что и свечение, а удар пришел с противоположной стороны, куда ушло свечение"."… distant sound came even before the beginning of glowing, it was like distant airplane hum. Sound came from the same side as glowing. The blast came from the opposite side, where the glowing went. "

http://www.space.com/19966-russian-meteor-asteroid-deflection-options.htmlRussian Meteor Fallout: What to Do Next Time?by Leonard DavidDate: 26 February 2013 Time: 03:12 PM ETThis month's meteor detonation above the Russian city of Chelyabinsk and Earth's close shave with asteroid 2012 DA14 have kick-started conversations on lessons learned and what steps can be taken to prevent space rock impacts in the future.One positive action item was actually in place prior to the dual asteroid events of Feb. 15: a new Memorandum of Agreement between the Air, Space, and Cyberspace Operations Directorate of the Air Force Space Command and NASA’s Science Mission Directorate.That document, which was signed on Jan. 18 of this year, spells out specifics for the public release of meteor data from sources such as high-flying, hush-hush U.S. government space sensors.The recent Russian meteor event occurred after completion of the newly signed agreement and data on the recent Chelyabinsk event had been released for scientific analysis, SPACE.com has been informed by NASA and the U.S. Air Force.As a result of that agreement, NASA’s Near Earth Object (NEO) Observation Program is receiving information on bolide/fireball events "based on analysis of data collected by U.S. government sensors."http://neo.jpl.nasa.gov/fireballs/
There is some speculation... that the Younger Dryas was punctuated by one or more North American impacts of regional affect. Just south of one of the Great Lakes, there is what looks like a melt-path, clearly viewable on google earth satallite imagery, where it sorta looks like a bunch of the native rock there was flash-melted then flowed. Also, there are a bunch of small lakes/depressions across the mid-east of North America that are perhaps impact related. IIRC, there was even some shocked quartz found related to Younger Dryas impacts, and some regional char layers here and there. Some suggest that an alternate theory for the giant floods that have been documented during the last glaciation, is flash-melting of enormous volumes of continental ice sheet, as opposed to ice bridges/plugs letting go. There is debate about the conclusions and scale, but I think that in a couple decades the consensus will tip toward the impact hypothesis.
