Possible Tsunami Deposits On The Caribbean Coast Of The Yucatán Peninsula, Charles Shaw, Larry Benson
Possible Tsunami Deposits On The Caribbean Coast Of The Yucatán Peninsula, Charles Shaw, Larry Benson
United States Geological Survey: Staff Publications
The western Caribbean Basin is notable for its tectonic stability. It has experienced no historical earthquakes or the tsunami that sometimes accompany them. This paper describes a single, wedge-shaped, boulder-covered, coastal berm on the Yucatán coast of México that stretches unbroken for 50 km across a coastal segment characterized by rocky headlands that alternate with crescent beaches. The remainder of the 350 km of Yucatán coast consists mostly of mangrove that extends 1 to 30 km inland, often behind long, sandy beaches. On the headlands, the surface of the berm is densely paved with boulders—large boulders on its seaward face …
Sediment And Discharge Yields Within A Minimally Disturbed, Headwater Watershed In North Central Pennsylvania, Usa, With An Emphasis On Superstorm Sandy, Kelly O. Maloney, Dustin R. Shull
Sediment And Discharge Yields Within A Minimally Disturbed, Headwater Watershed In North Central Pennsylvania, Usa, With An Emphasis On Superstorm Sandy, Kelly O. Maloney, Dustin R. Shull

We estimated discharge and suspended sediment (SS) yield in a minimally disturbed watershed in North Central Pennsylvania, USA, and compared a typical storm (September storm, 4.80 cm) to a large storm (Superstorm Sandy, 7.47 cm rainfall). Depending on branch, Sandy contributed 9.7–19.9 times more discharge and 11.5–37.4 times more SS than the September storm. During the September storm, the upper two branches accounted for 60.6% of discharge and 88.8% of SS at Lower Branch; during Sandy these percentages dropped to 36.1% for discharge and 30.1% for SS. The branch with close proximity roads had over two-three times per area SS …
