Ice volcano

For ‘Mission Backup Earth’ (Sci-fi series), an ice volcano was modeled using impulses from real ice cracking. A trash bag dropped with snow on the top simulating a large rock hitting the camera gave a nice thud followed by the snow / ice falling off the top hitting the floor.
The debris field of ice/rocks landing around the viewer was made using slowed down water droplets hitting a hot plate.
