How do hurricanes leave storm surge marks in coastal geology?
Quick Answer
Powerful winds and low pressure pile seawater onto land, and the surge can erode, bury, or reshape coastal sediments.
The Full Story
Storm surge is the rise in sea level pushed by a hurricane's winds and pressure drop. When it floods coastal areas, it can erode dunes, move sand inland, and leave layers of marine sediment over wetlands or barrier islands. Geologists study these deposits to reconstruct past storms, sometimes using marsh cores and overwash layers. Such evidence helps reveal the history of major storms long after the water has receded.
Key Facts
1.Storm surge can reshape coasts
2.Overwash layers can be preserved in marsh sediments
3.Geologists use sediment cores to study past hurricanes
