Seismic activity. Earth tremors. A mug of coffee at the beginning of the earthquake is on the table in the office. At first, the earth tremors are almost imperceptible and the liquid in the mug is almost static, but over time, seismic activity grows and coffee on the table begins to spill, the table in the office sways. The waves in the mug are getting stronger and stronger and the coffee spills onto the table. High quality 4k footage
