In response to the September 18th Chishang earthquake, the Fourth River Management Office enhanced the hydraulic structures inspection and contingency measures
A strong earthquake of 6.8 on the Richter scale occurred in Chishang, Taitung on September 18th, which affected bridges and hydraulic structures in the eastern region. Self-inspection will begin from today to inspect various hydraulic structures.
Up to now, several inspections have been completed for the potential hot spots of barrier lakes and related hydraulic structures in the Zhuoshui River Basin.
The drone photography survey of hydraulic structures was also carried out for the Chenyoulan River and its tributaries, which experienced higher earthquake intensity.
No hydraulic structures in the Zhuoshui River Basin were significantly damaged, and no barrier lake was formed.
Local volunteers and village chiefs will continue to help monitoring the river conditions and water level.
We would like to remind the public to follow "Drop, Cover, and Hold on" principle when you are indoors during an earthquake. It is suggested to avoid going to the mountainous areas during heavy rains. It is necessary to dredge the ditch in front of citizens’ house and to remove the obstruction of the ditch cover during flood season.
因應0918池上地震 四河局強化水利建造物巡檢及應變措施
台東池上於(18)日發生芮氏規模6.8強震，對於東部地區橋梁及水利建造物造成影響，為強化濁水溪流域水利構造物之安全，防範於未然，本局同仁及防汛護水志工自18日起即啟動自主檢查，巡檢各項水利建造物。
截至目前為止，已針對堰塞湖熱點(廬山、頭坑野溪匯流口、草嶺、車心崙及合流坪)與濁水溪流域相關水利建造物完成多次巡檢，及於今(20)日針對轄區地震震度較大區域之陳有蘭溪本流和社橋上流及支流和社溪辦理水利建造物空拍調查工作，防汛護水志工亦即時啟動巡防協助提供現場最新狀況與照片，目前本局轄管濁水溪流域內之水利建造物皆無明顯受損，亦無形成堰塞湖；後續將持續以CCTV、下游水位站及安排當地志工或村里長協助監看河道狀況及水位變化。另本局亦針對震後及後續可能形成之颱風，率定完成濁水溪流域各防災熱點之各項防災警戒及應變機制，含警戒雨量及流量值、水位CCTV及沖刷粒子監控、防災系統簡訊及通報、水情研判開口合約進駐待命及河道疏通等災害應變機制，以防範災害於未然。
在此提醒民眾，於地震發生且位於室內時，謹記「趴下(Drop)、掩護(Cover)、穩住(Hold on)」的避難原則，震後山區土石鬆動豪雨期間盡量避免前往山區，且汛期應加強家門前水溝清淤及溝蓋阻塞物清除，以利社區排水，協助政府水情災情通報，並應善加利用水利署水情App、防災資訊服務網（https://fhy2.wra.gov.tw）、濁水溪流域水情中心網站
