Popis:	This paper deals with event-based feature extraction to analyze the incubation time of coral under two stressor: temperature and light intensity. The study is conducted in Kho Sichang Island, Thailand during hot season. The method for extracting the important events is Hilbert Huang Transform (HHT). The event as a result of Empirical Mode Decomposition (EMD) and Instantaneous Frequency (IF) are confirmed with the time duration of first symptom appearance in Acrophora Hummilis coral. The result shows variation of incubation time of coral disease under different event combination. The important finding in this research is incubation time of coral disease under different situation. It is important for early warning in coral damage.
