Conference Paper
Full-text available
We present a graphical model based approach for on-line state estimation of water distribution system failures during large-scale disasters. Water distribution systems often exhibit extreme fragilities during large-scale disasters (e.g., earthquakes) resulting in massive pipe breaks, water contamination, and disruption of service. To monitor and id...

Conference Paper
Full-text available
This paper documents the results of an effort to benchmark modeling results generated from the newly-developed HAZUS Tsunami methodology. Although quantitative comparisons between HAZUS-modeled output and observations of damage from actual events are made, this analysis is considered preliminary in that data from only two events were used in the be...
Conference Paper
The combination of crowdsourcing and high-resolution aerial and satellite imagery have recently been explored in applications of post-disaster damage assessment and analytics. The large scale and distributed nature of these tasks produce overwhelming amounts of information that can be used to quickly assess post-disaster damage. While crowdsourcing...

Article
Disaster experts around the world have continually warned governments and the public about the possibility of “worst-case” natural hazard scenarios and their overwhelming impacts. Yet, planning for the occurrence of these events has fallen far short of need. The large earthquake that occurred off the coast of Sumatra in 2004, which resulted in one...

Article
Full-text available
Assessments of damage following the 2010 Haitian earthquake were validated by comparing three datasets. The first, for 107,000 buildings, used vertical aerial images with a 15-25 cm spatial resolution. The second, for 1,241 buildings, used Pictometry images (oblique angle shots with a resolution of about 10 cm taken in four directions by aircraft)....

Chapter
Earthquake loss estimation — although around since the early 1970’s — has not been considered a decision-making tool until recently. Because early models were based on expert opinion with limited hand calculations, they lacked the ability to perform sensitivity studies (which could provide important insight into drivers of loss potential) or the ab...
