Indian Ocean tsunami reshaped the coast of Sumatra

01-23-2021


Today’s Video of the Day from the USGS shows how one of the worst natural disasters in history reshaped the coast of Sumatra, Indonesia. 

In December of 2004, an earthquake off the coast of northern Sumatra was so intense that it lifted the seafloor several meters and sent tsunami waves in every direction. The 9.1-magnitude Indian Ocean Earthquake ranks as the third must powerful on record. 

Waves that reached the coast of Sumatra were as high as 30 meters. Landsat images show where the vegetation was completely stripped away along the coast, as well as the recovery in the years that followed.
