Tsunami deposits linked to the 1693 tsunami have been found both onshore and offshore . At Ognina , just south of Syracuse , at the head of a ria , a sequence containing several coarse clastic layers has been found , inconsistent with its lagoonal setting . The uppermost coarse layer , which has a strongly erosive base , consists of coarse sand with up to granule size clasts . The layer has been dated as 17th to 18th century based on pottery shards and one well-preserved clay pipe , consistent with the 1693 tsunami . Offshore from Augusta , a sequence identified using chirp sonar data was sampled with a gravity core in of water . Following detailed analysis of both grain size and foraminifera assemblages , eleven possible high-energy events were found based on the presence of large numbers of shallow water forams combined with a greater proportion of fine sand in the same interval . The uppermost two events correlate well with the tsunamis from the 1908 Messina earthquake and the 1693 earthquake
