The Tunguska Event
The power of the blast felled trees outward in a radial pattern over an area of 2,150 square kilometers, more than half the size of Rhode Island.

In 1908 near Tunguska in Siberia a meteor probably consisting of loosely bound pieces about 60 meters (200 ft) in diameter completely disintegrated before hitting the ground, so no crater was formed; however, all the trees were flattened and wildlife killed in an area 50 km (30 mi) in diameter, more than half the size of Rhode Island.
