A 400-year sediment record of tsunamis in Qi'ao Island, centered at Guangdong-Hong Kong-Macao Greater Bay Area

This supporting information includes the calendar and ¹⁴C ages of organic matter (OM) and shells (Table S1), the identifying proxies distinguishing this tsunami deposit from storms on Qi'ao Island (Table S2), the ²¹⁰Pb chronology of the QAD-ZK3 core (Text S1), the Cornell Multi-grid Coupled Tsunami model (Text S2), the probabilistic tsunami hazard analysis (Text S3). The dual-carbon (δ¹³C and C/N) mass balance mixing model to quantify OM sources (Figure S1).
