雨 ‘rain’ over 辰 chén. Thunderclap is léishēng 雷声 or pīlì 霹雳, earthquake is dìzhèn 地震, earth and shock.
辰 chén: 5th of 12 Earthly Branches (Dragon), 7-9 A.M., east, time, day, occasion, time-marker, celestial bodies. Wenlin: it may have depicted an ancient kind of hoe.

Triangular-shaped stone ploughshares are found at the sites of Chinese Majiabang culture dated to 3500 BC around Lake Tai. Ploughshares have also been discovered at the nearby Liangzhu and Maqiao sites roughly dated to the same period.
