(1) In general, both shock waves from airbursts and tsunami waves from ocean impacts may present serious hazards to populated areas.

(2) There is in fact an optimum height for airbursts, at which they devastate the maximum amount of area on the surface.

(3) Our final source of information about large airbursts is eyewitness reports.

(4) An airburst ignites flammable materials out to distances of many kilometers from ground zero.

(5) FIG. 2 Airburst altitudes for four 15-Mton stony asteroids with different incidence angles.

(6) Increased knowledge of the behavior of airbursts has led to a better understanding of mysterious aerial explosions that occur frequently on Earth.

(7) Within a few years[ ], the airburst theory gained scientific support and thereafter limited further speculation.

(8) We therefore expect the Tunguska fireball to have reached a height above its airburst altitude appropriate to a nuclear surface burst.

(9) The Great Daylight Fireball of 1972 was possibly the size of a small truck, and would likely have created an impressive airburst were it to have struck Earth more directly.

(10) By researching the efficiency of airhurst fire, the paper establishes the cubical elliptical damage rule, and using it to assess airburst fire efficiency.

(11) Two different weapon projects were initiated to use the new high-explosive airburst technology.
