Why were rituals performed at Mount Tai for harvests floods and earthquakes?

Rituals were performed at Mount Tai for harvests, floods, and earthquakes because the mountain was regarded as the chief ceremonial center for eastern China and was believed to be home to powerful spirits who influenced these events.1

Specifically, rituals were conducted in the spring to petition for a successful harvest and in the autumn to offer gratitude for a completed one. Because the mountain was viewed as a site of immense spiritual authority, rites were also performed to seek protection from natural disasters, including floods and earthquakes. These practices were deeply connected to Daoism and folk religion, as the mountain was considered the center of the yang principle and the source of life, with spirits believed to determine human destiny.1
