also, what do you mean referencing the size of the blast? This is from the NYT, updated at 4:46 PM today.
"U.S. intelligence agencies have reported to the White House and Congress that there was only light structural damage to the hospital following the blast, and no impact craters on the hospital. Two structures near the main hospital took light damage to their roofs, but the structures remained intact.
On Wednesday, U.S. officials said they were looking closely at an explosion next to the hospital in its courtyard or parking lot, to see if that was responsible for some or much of the loss of life."
