• WC/ATWC acquires seismic data from various seismic networks throughout its AOR. This data is processed, automatically and interactively, to quickly determine the tsunami-potential of an earthquake. • Bulletins are issued based initially on this first analysis of seismic data. • If a tsunami could have been generated, sea level data and historical tsunami information are analyzed to estimate impact level. • Based on impact estimations, supplemental bulletins are issued.
