Earthquakes can cause 25- meter-high tsunamis in Ecuador

Chilean researchers from the Seismic Risk Program of the University of Chile show that an earthquake of magnitude 8.6 can cause 25-meter-high waves in Ecuador.

The central coast of Peru can expect the highest tsunamis. Simulations show a flood margin between 25 and 45 meters for this area.

For Chile, the simulations produced the worst scenarios for the northern areas of Arica and Iquique, where tsunamis can be higher than 30 meters in Arica, and between 35 and 40 meters in Iquique. Valparaíso, on the central coast of Chile, can suffer tsunamis of between 30 and 35 meters.

In Colombia, an 8.7 earthquake can cause a maximum wave height of 20 meters.

The researchers believe that the scenarios that they used can occur in reality. They refer to an earthquake in Japan in 2011 where the subsequent tsunami reached over 40 meters in height.

The study has been published in the journal Pure and Applied Geophysics.
