THE EARLY EFFECT OF AN EXPLOSION IN A MULTI-LAYERED MEDIUM,
Abstract
When an explosion occurs on or in a sheet water overlying a geological formation consisting of horizontal strata, the earliest impulses reaching an observer consist of dilational waves only. This makes it possible to neglect distortional waves and to consider the medium as being acoustic in nature with velocity of propagation that of the dilational waves. Except quite near the explosion, linear acoustic theory may be used with the actual explosion source replaced by an equivalent linear singularity. The general multi-layer theory is developed. The theory of the initial pulse is completed for the case in which the medium below the water is homogeneous without stratification. The result is specialized to the case of an exponential type source.
