The Pacific Tsunami Warning Center (PTWC) is an organization that monitors seismic activity in the Pacific Ocean to detect potential tsunamis. Established in 1949, it provides timely warnings to countries in the Pacific region, helping to protect lives and property from tsunami threats. The center uses data from seismic sensors and ocean buoys to assess tsunami risks. PTWC operates under the umbrella of the National Oceanic and Atmospheric Administration (NOAA) and collaborates with various international agencies. Its mission includes educating the public about tsunami safety and preparedness, ensuring communities are better equipped to respond to tsunami events.
