In what year was the Pacific Tsunami Warning Center (PTWC) established in Honolulu, Hawaii?
Answer
1948
The Pacific Tsunami Warning Center was established in 1948, just two years following the devastating tsunami generated by the 1946 Aleutian Islands earthquake. The creation of this facility marked a shift from reactive, ad-hoc responses to disasters toward a proactive, centralized model dedicated to monitoring seismic activity and issuing timely alerts before destructive waves reached inhabited coastlines.
