And there may be a 'recent' Arabian Tunguska that may have wiped out a merchant city/town.
In the Arabian peninsula, in the desolate region known as
Rub Al Khali [Empty Quarter] there is a filled-in crater
that may have been created by an small asteroid
that may have wiped out an ancient Arabian merchant/trading
settlement [town] known as Ubar.
The asteroid that may have leveled and buried the town
as recent as 1400 years ago according to the Koran.
According to one scientist, the small asteroid may have impacted with the
energy of the Hiroshima blast.
Maybe 1000's died.
Recent geological and archaeological offer some new evidence
to support it.
