NASA Radar Image Shows Topography of Sendai, Japan Region
The topography of the earthquake and tsunami-stricken city of Sendai, Japan, is revealed in this radar image from NASA's Shuttle Radar Topography Mission. On March 11, 2011, a magnitude 8.9 earthquake struck offshore about 130 kilometers (80 miles) east of Sendai, the capital city of Japan's Miyagi Prefecture, generating a tsunami that devastated the low-lying coastal city of about 1 million residents.
This image combines a radar image acquired in February 2000 during the SRTM mission, and color-coding by topographic height using data from the same mission. Dark green colors indicate low elevations, rising through yellow and tan, to white at the highest elevations.
