1877-05-10 tsunami – NORTHERN CHILE: Historical Tsunami Record and Measurements

On May 10, 1877 CE, a major tsunami struck northern Chile, leaving a significant historical record of destruction and high-energy wave measurements. According to the NOAA/NCEI Global Historical Tsunami Database, the event was directly associated with an earthquake measuring magnitude 8.3. The historical tsunami record indicates a maximum water height of 18.0 meters and resulted in 2,385 recorded deaths.

Event Parameters and Historical Measurements

Official historical records cataloging the event classify its validity with a high degree of certainty (validity rating of 4) and trace its origins to an undersea or coastal earthquake occurring at 00:59 hours on May 10, 1877 CE. The generated waves reached a maximum water height of 18.0 meters in the affected region of northern Chile. This height represents the peak recorded runup or inundation measurement for the event rather than a uniform height along the entire coastline.

Impact and Casualties

The combination of the magnitude 8.3 earthquake and the subsequent tsunami waves led to a severe human toll, with 2,385 fatalities documented in the historical database. The event stands in the historical record as a major tsunami with extensive loss of life, illustrating the severe seismic and hydrodynamic hazards inherent to the tectonic subduction zone off the coast of northern Chile.
