And a meteor that buries itself into the ground and liquifies is called a magmeorite.
At least read the thread before posting a "correction" that you assume, incorrectly, is needed.
Anyways, NASA is upgrading their estimated size to around 60 feet and the explosion energy to about 500 kilotons. I just read a story about a teacher that pulled the old cold war duck and cover instructions to her students, her students were unscathed as the shock wave blew out the windows of her classroom, while she was badly cut up. Apparently duck and cover still has value, yeah if you're near the blast you're screwed, but if you're in the periphery it could save you from injury.
