“…The images are corrected for comparable scaled time, and displayed next to each other in Figures 3b and 3c. We note that the following features are consistent with features discussed by Cole [1948] and Kedrinskii [2005].…”

“…This means a considerable fraction of the shockwave energy is converted into the kinetic energy of the water drops. These energy losses are considered more significant in a larger explosion, in which a larger area of water experiences tensile stress above the fracture strength [Kedrinskii, 2005]. Therefore, the airwave weakening was observed in the E01 experiments but not in the E04 experiments.…”

“…However, the purpose of this paper is not to present empirical similarity laws for underwater explosions to compare with phreatic eruptions, but to understand the mechanisms that generate features of the airwaves in relation to the scaled depth, underwater pressure waves, and motion of the surface. Mechanisms and similarity laws for the surface motion and underwater pressure waves have already been given in the literatures [Cole, 1948;Kedrinskii, 2005], but only a few studies discussed airwaves [Kuwabara et al, 1987;Adushkin et al, 2004]. Therefore, experimental results and analyses presented in this paper are new in the research of underwater explosions as well as in the volcanology, and knowledge obtained by this study will be useful in developing tools for both volcanological and engineering applications.…”

“…[13] All the above mentioned phenomena, the underwater pressure waves, the behaviors of the bubble, and the motion of the water surface, have already been studied in detail [Cole, 1948;Kedrinskii, 2005]. In the present paper, we investigate the pressure waves induced by these phenomena in the atmosphere.…”

[1] A shallow explosion in a fluid is one of the fundamental processes of airwave generation in volcanic eruptions. To better understand the mechanism of the airwave generation, underwater explosion experiments were conducted. Although the underwater explosions have been intensely studied over the last century, airwaves have received little attention. In this study, pressure waves were measured in air and under water, and the corresponding motion of the water surface was captured by a high-speed video camera. Airwaves and associated styles of the surface motion show similarities determined by the scaled depth, defined as the depth divided by the cubic root of the explosion energy. The air waveforms are quite different from the pressure waves measured in the water and cannot be completely explained by linear transmission of pressure waves from water to air. The mechanism of airwave generation is a combination of wave transmission and dynamics of the interface boundary. The first mechanism directly reflects the explosion source, and the same source is also observed as the underwater pressure waves. On the other hand, the second is not necessarily visible in the underwater pressure waves but will provide information on the mechanical properties and behavior of the material above the explosion source. Each mechanism is analyzed in the experiments.

To calculate the shockwave propagation of deep water explosions for different explosives quickly and accurately, a calculation method, based on the Kirkwood-Bethe theory, was proposed. At the same time, an underwater explosion experiment of the aluminized explosive was carried out in the pressure vessel under high hydrostatic pressure. Then, the calculated results and experimental results were compared for peak pressure, impulse and energy flux density. The results indicated that the proposed method can quickly and accurately determine the shockwave propagation of deep water explosions for the aluminized explosives, with satisfactory agreement with experimental data. Using the proposed method, the shockwave of aluminized explosive under the conditions of different charge weight, different depth and different distance were calculated, the propagation laws of peak pressure, impulse and energy flux density with depth and distance were obtained. The calculation method proposed could be used to calculate shockwave propagation for any kind of explosive, if only knows the parameters of detonation and JWL equation of state.
