1. Tsunami Quantifying tsunami risk submarine slides submarine slides 1881 Mw=7.9 1941 Mw=8.0 using SRTM digital elevation data and scenario earthquakes Partial text of a NASA sponsored talk given in Bangalore June 2004 View-->notes for narrative 1524,1845 Makran

2. 1881 1941 W. coasts of Andaman & Nicobar Islands repeatedly uplift by tsunamigenic earthquakes W. coasts of Andaman & Nicobar Islands repeatedly uplift by tsunamigenic earthquakes Andaman plate Andaman plate Next slide shows SRTM evidence for incremental uplift of North Sentinal Island zone of coseismic uplift

3. 10 m 20 m 30 m Marine terraces suggest a history of great earthquakes

4. 1m Chennai Tsunami run-up estimates from SRTM data for different tsunami maxima suggest that large tsunamis may leave a record in coastal swamps

5. 3m Chennai Tsunami run-up estimates from SRTM data for different tsunami maxima suggest that large tsunamis may leave a record in coastal swamps

6. 5 m Chennai Tsunami run-up estimates from SRTM data for different tsunami maxima suggest that large tsunamis may leave a record in coastal swamps

7. 7m Chennai Tsunami run-up estimates from SRTM data for different tsunami maxima suggest that large tsunamis may leave a record in coastal swamps

8. 9m Chennai Tsunami run-up estimates from SRTM data for different tsunami maxima suggest that large tsunamis may leave a record in coastal swamps

9. Summary: Remote sensing India's earthquakes 1. Monitoring mechanics of earthquakes 2. Quantifying India's earthquake history 3. Quantifying tsunami risk 4. Predicting earthquakes not possible but identifying damage within minutes of an earthquake an important application.
