Under The Ice at Libby Brook
In February 2005 a visit to a USGS station on Libby Brook near Northfield, Maine revealed a gap between the water level and a layer of ice above. Cold temperatures after a rain event caused the ice layer to form and as water levels dropped the ice layer remained.

Banda Aceh after the December 2004 Earthquake and Tsunami
An International Tsunami Survey Team studying the effects of the December 26, 2004 tsunami on Indonesia“‘’’s island of Sumatra documented wave heights of 20 to 30 m (65 to 100 ft) at the island's northwest end and found evidence suggesting that wave heights may have ranged from 15 to 30 m (50 to 100 ft) along at least a 100-km (60 mi) stretch of the northwest coast.
