we are studying the crack formation due to volcanic eruption and measurements of gravity anomaly due to magma-filled dikes. This is done with the help of quantum gravimeter which is based on atom interferometer. We will also demonstrate the gelatin based model to study the crack propagation . Some other fluids of different densities and viscosity are injected and crack formation is demonstrated in analytical laboratory experiments.
We will try to estimate the shape and volume change of magma-filled dikes. The observed gravity changes due to volcanic eruption are estimated by studying underground mass redistribution, which is measured with the quantum gravimeter.
