| Research Abstract |
Gravity effect on propagation waves in a solid medium is not considered, whereas the effect may be important to discuss the propagation waves in a liquefied ground. We simulate wave propagation in a liquefied ground introducing the gravity effect. The wave exhibits the similar property with the gravity wave in a fluid medium as decreasing the shear modulus, and sloshing behavior is excited in the medium.
