Photos from Surveys of the 11 March 2011 Mw9 Tohoku Japan Earthquake and Tsunami.
Charles Scawthorn visited areas affected by the 11 March 2011 Mw9 Tohoku Japan Earthquake and Tsunami in three surveys in company with Japanese and American colleagues, in order to document and understand the damage resulting from these events. The tracks of the three surveys are shown in the map below (the tracks are overlaid on a muted map of the peak ground accelerations caused by the earthquake - the three surveys were 29-30 March shown in orange, 11-13 April shown in blue and 18-20 April, 2011 shown in green; also shown in magenta is a half day fourth visit to Urayasu in metro Tokyo).
The approximately 2,400 photos are all georefernced with the latitude-longitude written into the photo file name, and are divided into three pdfs with links below - each pdf corresponds very closely to each of the three surveys (there is minor overlapping of surveys at the ends of each pdf). Photographs are copyrighted by SPA Risk LLC. Viewers are free to use the photos for non-revenue generating non-commercial purposes. Due to file size limitations, the images are significantly downsized and quality unfortunately reduced - please contact email@example.com for access to higher quality copies of the images.
