A severe earthquake of magnitude 8.1 occurred at Taiwan at about 3:04 p.m. on 11 Aug 2009. The earthquake is expected to generate a tsunami that affects the South China Sea. If the tsunami persists, it would reach Hong Kong around 5:05 p.m. and recur at intervals of 5 to 60 minutes. In the couple of hours following the arrival of the tsunami, sea-levels in Hong Kong would rise to about 0.5 - 1.5 metres above chart datum, or equivalently about 2.0 - 3.0 metres above normal tide level. Flooding may occur in low-lying coastal area. Precautions should be taken for the sake of safety. Tsunami heights recorded around : 4.0 m 1. Stay away from shores, beaches and low-lying coastal areas. If you are there, move inland or to higher grounds. The upper floors of high, multi-storey, reinforced concrete building can provide safe refuge if there is no time to quickly move inland or to higher grounds. 2. Do not engage in water sports. 3. Vessels should stay away from the shore or shallow waters. If vessels remain moored in typhoon shelters, their moorings should be doubled and all personnel should leave the vessels and head for higher grounds. 4. Please observe these precautions until the Observatory cancels the tsunami warning. 5. Please stay tuned to the radio or television for further information.
