This image shows NOAA modelling of the tsunami that followed Chile’s earthquake – which proved to be highly accurate. Yale Environment 360 explains how to decipher the map:
Researchers used seismic information, wave measurements collected from buoy-based equipment, and computer modeling technology to predict the maximum wave amplitude, wave arrival time, and the extent of wave inundation. The colors illustrate the maximum computed tsunami amplitude in centimeters during the 24 hours after the quake, with the highest waves in purple and red and smaller waves in orange and yellow. The red triangles represent buoys.
