3rd April 2024 – (Hong Kong) The Hong Kong Observatory issued a Tsunami Information Bulletin at 11.10am today in response to a powerful earthquake measuring 7.3 magnitude that struck Taiwan at approximately 7.58am.

According to the bulletin, the earthquake has the potential to generate a tsunami in the South China Sea. If the tsunami persists, it is projected to reach Hong Kong between 12noon and 1pm, recurring at intervals of 5 to 60 minutes. The anticipated impact is expected to exceed the normal tide level by a maximum of approximately 0.1 metre, resulting in minimal effects on Hong Kong.

The Hong Kong Observatory provided the following information about the predicted normal tides for the day:

  • High water at Quarry Bay: 2.09 metres at 3.36pm

Meanwhile, two flights departing from Hong Kong to Okinawa had to be diverted. Naha Airport, located near the coastal areas, experienced a significant influx of people seeking refuge on the third floor following the issuance of a tsunami warning by authorities. In response, incoming flights were temporarily suspended, and certain flights were redirected to Kagoshima and Miyazaki airports. Narita Airport also reported that three departing flights had to return due to the circumstances.
