Mark Legg has looked into this and may have something. The quick answer is "I don't know", but I do have some comments. I think Carpinteria Salt marsh amd maybe Deveraux (sp?) slough and the marshes near Santa Barbara airport would be good places to look for Santa Barbara Channel tsunamis. There was a few m-high tsunami at "Surf" from the 1927 Lompoc earthquake. There were some stories about the 1812 tsunami being large, and a ship being washed up a canyon, but this was not able to be confirmed. In my thesis I quote an oral history from Heizer 1955. "In 1812 the great earthquake occurred on the California coast abd at that time every soul left the island of S. Rosa. The waters receded from the island several hundred yards. This so alarmed the indians that, fearful that the island was about to be engulfed, they departed and were settled in bands of three or four hundred at several missions." (Heizer, 1955). It is not quite accurate-baptism records show the indians left the island a couple of years after the quake. The retreat of the water, if accurate, is either temporary: a tsunami, or permanent, a thrust uplift of the island. There is a possible area on the island to core and see if there was a permanent uplift. There is a large landslide complex offshore SW of UCSB: it may date from 1812 and could be the source of the tsunami. Chris
