Decrease of the velocity of a pressure wave in magma by the presence of bubbles is regarded as a fundamental process in seismoacoustic activities of a volcano. However, we show that the large viscosity of magma (≥105 Pa ...
The main purpose of the present paper is to present the mathematical expression for the frequency-dependent effective acoustic properties of a liquid–bubble mixture. Effects of the bubble resonance, the heat and mass ...
