are more likely to have damage due to the critical combination of damaging shaking levels and greater vulnerability (within 10 minutes)
magnitude and epicenter identified (within 1 minute)
4
Earthquake shaking forces exerted on bridges, roadway and facility locations are determined from USGS ShakeMap. At each bridge, roadway and facility location, ShakeCast analyzes the measured/interpolated ground motion against a pre-determined fragility model. Earthquake shaking forces exerted on bridges are determined from USGS ShakeMap. Probabilities of damage relative to varying levels of shaking (or “fragility”) can be determined in advance for each bridge.
5
…because magnitude and epicenter alone aren’t enough to determine the area of strong shaking. In California, an array of over 1900 seismic sensors are operated by the California Integrated Seismic Network (CISN).

Low Priority for Inspection Medium-High Priority for Inspection
Bridges that may appear similar can have very different performance characteristics under the same ground shaking conditions.

ground motion.
– Post-1991 designs perform better than pre-1971 – Short, single-span bridges have performed well in past earthquakes – Bridges with no skew perform better than those with higher skew

ShakeCast identified the only bridge damaged in this event as the top priority for inspection. 7.2 Calexico April 2010
22
ShakeCast identified the 9 bridges that sustained minor damage. These bridges were in the top 40% of a ShakeCast list of 87 bridges. Over 2700 state bridges were in the area. 6.0 Napa August 2014

ShakeCast ‘canned’ maps are available for planning, exercise, and training use. Evaluating system performance and supply chain response capabilities before the earthquake occurs.

“Earthquakes are one of the most costly natural hazards faced by the United States, posing a significant risk to 75 million Americans in 39 States”.
The ShakeMap Atlas Database consists of approx 1,000 recent and historical earthquakes worldwide with input peak ground motions, macroseismic intensity data well as information from approx 600 recent + historical global events
28
“The GSN provides near-uniform, worldwide monitoring of the Earth, with over 150 modern seismic stations distributed globally. Data from the GSN are archived at the IRIS Data Management Center.”.

Opportunities exist to host a seismometer in your private home, business, public building or school in the United States and around the world.

“The NetQuakes seismographs access the internet via a wireless router connected to your existing broadband internet connection. The seismograph transmits data only after earthquakes greater than magnitude 3 and otherwise does not consume significant bandwidth”.
