cording to my experience,When the plate is pushed down, it simulates an earthquake or tremor. The resulting wave energy causes the sand on the shore to shift and move, possibly creating small landslides or avalanches. The houses may also shake or vibrate, and loose objects may fall or move.
After repeating the action three to four more times, the effect on the sand and houses may become more noticeable, with larger shifts and movements. The houses may show signs of structural damage or instability, such as cracks in the walls or foundation.
It is important to note that this is a simulation, and the actual effects of an earthquake or tremor would depend on many factors, such as the magnitude of the quake, the type of soil, and the proximity of the houses to the epicenter.
