The Pacific Tsunami Warning Center (PTWC), located in Honolulu, Hawaii, plays a central role in monitoring seismic activity and issuing warnings for the Pacific Ocean region. Established in 1949, the PTWC is part of an international network of tsunami warning centers that collaborate to provide global coverage. The PTWC uses a sophisticated network of seismic sensors, deep-ocean assessment and reporting of tsunamis (DART) buoys, and coastal sea-level gauges to detect and monitor potential tsunami-generating events. When a significant earthquake occurs, the seismic sensors record the event's magnitude, location, and depth. This information is immediately analyzed by the PTWC to determine the potential for a tsunami. Earthquakes that occur underwater or near coastlines are of particular concern, as they are more likely to generate tsunamis.

The DART buoys are a critical component of the tsunami warning system. These buoys are deployed in strategic locations throughout the Pacific Ocean and are equipped with sensors that can detect changes in sea level caused by a passing tsunami wave. The buoys transmit real-time data to the PTWC via satellite, providing valuable information about the size, speed, and direction of a tsunami. Coastal sea-level gauges, which are located along coastlines, also provide valuable data on sea-level changes. These gauges measure the height of the water and can detect the arrival of a tsunami wave. The data from these gauges is used to confirm the existence of a tsunami and to refine the warning information. Once the PTWC has analyzed the data and determined that a tsunami threat exists, it issues alerts to affected areas. These alerts can take the form of tsunami watches, advisories, or warnings, depending on the severity of the threat.
