Abstract. Large boulders have been found on marine
cliffs of 24 study areas on Minorca, in the Balearic archipelago. These large
imbricated boulders of up to 229 t are located on platforms that comprise
the rocky coastline of Minorca, several tens of meters from
the edge of the cliff, up to 15 m above the sea level and kilometers away
from any inland escarpment. They are mostly located on the south-eastern
coast of the island, and numerical models have identified this coastline as a
zone with a high probability of tsunami impact. The age of the boulders of
the studied localities range between 1574 AD and recent times, although most
of them are concentrated around the year 1790 AD. Although some storm waves
might play a role in their dislodging, the distribution of the boulder sites
along the Balearic Islands, the degree and direction of imbrication and the
run-up necessary for their placement suggest transport from northern African
tsunami waves that hit the coastline of Minorca.
