25. What are the Central Weather Bureau's tsunami report/warning dissemination procedures?
The Central Weather Administration tsunami report/warning dissemination processes are as follows:
| (1) | When the CWB monitors a tsunami caused by an earthquake with wave height above 50 cm around the coastal area of this country, a tsunami report shall be issued immediately and be informed to the central emergency management authorities, relevant agencies, and the media, to take necessary actions. |
| (2) |
When the CWB judges a tsunami would arrive and influence the coastal area of this country, a tsunami warning shall be issued immediately with respect to different circumstances: (i) For tsunamis caused by distant earthquakes: When the CWB anticipates the tsunami would reach the coastal area in three hours, a tsunami warning shall be released and be reported to the central emergency management authorities, relevant agencies, and the media, to urge the coastal residents to get ready for action. (ii) For tsunamis caused by nearby earthquakes: When the CWB detects an along shore or coastal earthquake with a magnitude of 7.0 or above and a focal depth of 35 km or less, a tsunami warning shall be released and be reported to the central emergency management authorities, relevant agencies, and the media, to urge the coastal residents to get ready for action. |
| When the CWB judges that the tsunami threat has no more existed, a report on the termination of tsunami warning shall be issued accordingly. |
