An 1821 hurricane may have generated a storm surge, or perhaps even a tsunami after wave action generated an underwater landslide, that devastated Assateague and Chincoteague islands.
Residents reported that as the storm approached the coast from the southeast, the sea receded and exposed miles of ocean bottom. Soon afterward, a deep roar could be heard moments before a "monstrous wall of inky waters rushed with the speed of lightning toward the island." The wall of water struck Assateague first, decimating trees and anything else in its path, and then struck Chincoteague, carrying away men and ponies "like insects."
One man with his grandson clinging to his neck was reportedly swept far up on to the mainland six miles to the west. Another was found the next morning hanging in a pine tree by his waistband, twenty feet from the ground.1
The low-lying island is at high risk of flooding, particularly as land subsides and sea level rises. A nor'easter in 2022 triggered town officials to declare a state of emergency and call for a voluntary evacuation of the entire island. The Virginia Department of Transportation (VDOT) prepared to close the road on the causeway leading into town. The Chincoteague Emergency Management Department warned residents/visitors to fuel up vehicles, because gas pumps would not work if the island lost electricity.2

Today, Chincoteague economically benefits from its proximity to Wallops Island. Antares launches of resupply missions to the International Space Station bring tourists in the off-season. The general manager for Ropewalk Restaurant in Chincoteague reported in 2018:3

Chincoteague also benefits from its proximity to Assateague Island. For the last 2,000 years, longshore currents have carried sand south and extended the tip of Assateague Island. Today, it:4
