Degree VI Two: 154-177 kmh Tsunamis and storm surges are a threat to coastal regions, particularly gulfs, bays, and estuaries. The flood hazard Degree VII Three: 178-209 kmh Surat Thani Degree VIII Four: 210-249 kmh results from river floods and torrential rain. The hazard of !( dryness and drought is caused by major deviations from Degree IX-XII Five: 250+ kmh the normal amounts of precipitation.
