    Is there any material which changes into liquid state when given certain vibration such as earthquake? As we know that when we vibrate saturated sand, liquefaction takes places and the sandy soil totally liquefies. Anything above it will act as a floating structure at that time.
    Is there any other material that can be synthesized or is available that will liquify when vibrated? In normal state it should be rigid. When vibrated it should be liquid.

    What you are after is a pseudoplastic or a shear-thinning solid. Nothing comes to mind, but then again I've never purposefully looked for one. It is more common to find shear-thinning fluids (like ketchup or whipped cream).

    It's an interesting subject, but you should ask your question more clearly.
    What level of performance do you need from the behavior of these materials.

    Dear Ashesh, I am familiar with liquefaction but it is an unsafe situation for structures. Why do you want to liquefy a material? It sounds like an interesting research topic but it is important to define future applications. Some resources for you: http://www.matweb.com/ , https://www.engineersedge.com/manufacturing_menu.shtml , nature materials.
