The Asian nation experienced the deadliest tornado in recorded history in 1989, which ki...
The most common example of a minor whirlwind is a dust storm. While not as destructive as major whirlwinds, minor whirlwinds are still considered dangerous. Some minor whirlwinds, such as severe dust devils, have resulted in deaths. The most powerful dust devils produce winds with speeds nearly equivalent to tornadoes. Such minor whirlwinds are lin...
