  4. Sumatra-Andaman Earthquake: December 24, 20047:58AM9.3 magnitude1400km rupture along plates3rd strongest earthquake since 1900

  5. Run a change detection analysis in areas severely affected by tsunami. • Which landuse class is most greatly affected? • Is the area recovering? Objective

  6. Southeast coast of Sri Lanka - 100,000 + families affected • Banda Aceh, Indonesia - 1 million people affected throughout Indonesia Study Area http://www.navy.mil/view_single.asp?id=21839

  9. Table C. Banda Aceh Change Detection Analysis of the 2004 Tsunami.

  10. Sri Lanka: - 160km² of vegetation lost - 16km² of coastal villages were affected - Local water bodies increased in area by almost 8km² Recovery: -Vegetation gain of 99km² -Villages grow almost 6km² Summary

  11. Banda Aceh: - Lost 8km² of vegetation - Urban areas lost about 5km² Further Analysis: - ArcMap DSAS tool- quantify shoreline loss in Banda Aceh
