Meteorological history
On September 10, 1973, a tropical depression formed in the sea east of the Philippines before moving to the east of Luzon.

On September 13, Hainan Province was still unaffected by the circulation of Marge and the weather was humid. The weather forecast in a local newspaper, the Hainan Daily, only showed that the wind force would be 7 to 8 on the Beaufort scale on September 14, providing an insufficient warning. By evening, there was still no sign of an impending typhoon.
According to data from the Central Meteorological Observatory, Marge landed on Boao in Qionghai, Hainan District at 4:40 am on September 14. The wind at the center of the storm reached 60 meters per second and the pressure was 925 hPa.[3] During the landing, Qionghai's houses were almost completely destroyed. In Qionghai alone, there were 771 deaths.
The disaster report by the Revolutionary Committee of the Hainan Administrative Region to the Guangdong Provincial Party Committee showed that 90% of the houses collapsed, and some communes in Ding'an, Tunchang, and Changjiang also suffered varying degrees of damage.
Data from the Qionghai Meteorological Station on the north side of the landing site showed that it recorded a 10-minute average wind speed of 48 meters per second from 4:12 to 4:22 on September 14. The anemometer was destroyed later and the maximum wind speed could not be obtained. A sea-level pressure of 937.8 hPa was recorded at 4:40. The Central Meteorological Observatory evaluated that the central wind reached 60 meters per second and the pressure was 925
Typhoon Marge killed 903 people and injured 5,759 in Hainan Province.[4]
