On the subject of lightning in strange places. In the course of studying vulcanism, plinian eruptions, and severe pyroclastic flow, I was surprised to discover that heavy lightning was a major association.
Regarding sources of tsunamis and large ice as high as 600 feet, how high do scientists think the tsunami caused by a great chunk of mountainside sliding into the sea in the Canary Islands might have been?
In a separate vein, I have come to a moderately strong belief that there was an important boloid event associated with the Younger Dryas. At that time sea ice extended far down into the Atlantic. My intuitive hunch has been that the boloid whould have been in the upper north Atlantic. Any evidence for or against? As I said this is a strong hunch. Years ago I read something about tectite strew fields in Georgia and/or the Carolinas. I think the age they mentioned was around 12kya. Any info on this?
There doesn't seem to be a lot of agreement on the size of a tsunami generated from there. I've seen anywhere from 100' to 300' as estimates. Bottom line, it would be a doozy regardless.

Can't add anything to your comments but if you're able to dig up something else, it could be very interesting.
There is some evidence of an Arctic Ocean impact (that is, a sort of broad scar on the ocean floor, which has erroneously I believe been attributed to a glacial floe), but not that recently I don't think.
"....Years ago I read something about tectite strew fields in Georgia and/or the Carolinas...."
My friend Peter Vogt, a marine geophysicist, says that those tektites resulted from the meteorite that struck at what is now the mouth of Chesapeake Bay, at the end of the Eocene...which would be ~33.7 million years ago, NOT 12,000.
