National Tsunami Warning Center

The National Tsunami Warning Center (NTWC) is a government agency responsible for detecting potential tsunamis, which are large ocean waves caused by earthquakes or volcanic eruptions. Located in the United States, it monitors seismic activity and ocean data to identify signs of a tsunami. When a threat is detected, the NTWC issues timely alerts to emergency services and the public, helping communities prepare or evacuate to reduce risk. It plays a vital role in safeguarding coastal populations by providing early warnings based on scientific analysis and real-time data.
