1604 65438+On February 29th, an earthquake of magnitude 8 occurred in the sea area east of Quanzhou. In the past, many scholars concluded that it was a tsunami, because "there was an earthquake on the night of the ninth day of the first month, … houses inside and outside the city were smashed, rocks and seawater were moving, many ships were overturned, and Qingyuan Mountain was cracked in many places".
In recent years, some scholars think that this information is isolated evidence through comprehensive comparative analysis of relevant historical materials, and then use the tsunami wave records of the Taiwan Province Strait earthquake to estimate that the tsunami source only caused a small-scale tsunami water increase and water decrease effect in Quanzhou Bay, and did not have the conditions to form a destructive tsunami.
