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).
