AN ARCHAEOLOGICAL excavation in Estepona has revealed that the town suffered at least two ancient tsunamis, one in the ninth century and another between the first and fourth centuries.

Estepona is a popular site for archaeologists, particularly the historic centre, but geological phenomena are not normally their focal point.

However, researchers from the universities of Cambridge and Madrid have uncovered a sedimentary layer that confirms there was a tsunami at around 881, and another much earlier.

This is the first and only existing record of ancient tsunamis in southern Spain.

A large wave would be about six metres high and would reach around 20 metres deep, but a tsunami wave is over ten metres high and goes much deeper, dragging sediment and soil with it.

The Cambridge researchers will continue studies into the find in their laboratories, extracting a number of blocks of soil.
