Abstract
-
Storm and tsunami deposits have been identified and described from many siliciclastic coastlines globally,
but detailed comparison of both known storm and tsunami deposits from the same coastlines are lacking. An
opportunity to compare storm and tsunami sedimentary deposits was recognised following sediment deposition by
Cyclone Thane (25th to 31st December 2011) that were superimposed on sediments deposited during the Indian
Ocean Tsunami (26th December 2004) in a pit (DPM3a) near Cuddalore, on the south-eastern Indian coastline. A
second pit, at Silver Beach (SB1) was located 2 km south of Pit DPM3a, was examined for comparison with Pit
DPM3a.
