Wenchuan Megaquake 12 May 2008 Mw = 7.9 Length of Rupture 270 km Cost of Damage $ 150 B
Human Tragedy ~70,000 Fatalities ~17,000 Missing ~375,000 Injured ~5 M w/out Shelter
New County New Beichuan middle school Landslide Old County Wangjiayan Landslide Landslides Wangjiayan Slide killed 16,000 School Slide killed 900 students
1803 Dams Sustained Damage Including 3 Major Dams
Bridge Failuures 4840 Bridges and 98 Tunnels Damaged
On the positive side Invaluable data to be obtained
e.g. 70% of slides within 10 km of fault rupture Invaluable direct information if it can be confirmed and normalized
e.g. over 1200 strong-motion record components Max. Ground Acceleration ~ 1 g
If the ground motions are vetted and the damage carefully documented, The Immense Database will enable 1.Modeling from the crust of the earth to the crest of the built environment 2. Testing models for dam response 3. Testing methods for assessingearthquake vulnerability 4. Testing theories of spatial distribution of earthquake damage 5. Testing tools and theories for regional resilience 6. Developing new sensors and sensor networks
