Typhoons are one of the major global environmental disasters, and their variability is of great concern to modern society. However, the variability of typhoon activity and its climate drivers on centennial-millennial scales are less clear due to the lack of atmospheric instrumental records before the mid-19th century. Coastal sedimentary archives provide a means to extend our knowledge of typhoon dynamics, of which the effective identification of typhoon event layers is an important foundation. Although many studies have attempted to reconstruct typhoon activity on long time scales using various indicators and methods, there is still a lack of evaluation of the effectiveness of these indicators and methods for the identification of typhoon event layer. In this study, a high-resolution sedimentary record (Core ZM02) from the muddy belt of inner shelf of the East China Sea was used, and its dating framework was determined using ²¹⁰Pb and ¹³⁷Cs dating methods. The instrumental and sedimentary records were then coupled to analyze the correspondence between typhoon intensity and frequency and sensitivity indicators of typhoon deposits (i.e., sand content and D₉₀ in this study). The results show that the upper 4.5−100 cm of the core dates between 1917 and 2011 AD at a sedimentation rate of 0.97 cm/a. Among the three technical solutions, the threshold method was found to have the best identification and highest stability. Both sand content and D₉₀ were found to be effective indicators for the identification of typhoon deposits in the study area. Sand content may be a potential indicator of typhoon intensity variation along the Zhejiang coast, and D₉₀ contains information on typhoon frequency. The knowledge obtained here will not only contribute to the more accurate use of the sedimentary record to extend the time span of the typhoon record, but also to improve the ability to decipher information from the sedimentary record.
