Short summary
This work provides a simple and fast approach to improve tsunami warning systems in the near field. A color-coded warning map is produced almost instantaneously after the seismic information is received. Time is crucial in the near-field case; for instance, the tsunami waves generated in the Chilean trench arrive at the coastline in around 10–15 min. Seismic information takes 3–5 min to be ready; thus we produce a first warning map 6 min after the earthquake origin time.
