Reference #414:

On October 20, 1859 at 17;340 [local time] there was a strong underground shock, accompanied by a tsunami, at Patjitan (Java Island). The wave arrived precisely when the "Ottolina," which was riding in the roadstead, was getting ready to cast anchor. A sloop, loaded with anchor and chain, sank; of the crew of thirteen, 11 were saved.
