Introduction
With an average occurrence rate of 20,000 events worldwide every year, earthquakes have produced innumerable fatalities and economic loss (Fig. 1). For example, the recent Haiti earthquake (2010) was responsible for at least 300,000 injuries, 316,000 deaths, and 300,000 destroyed houses. There is a high demand for rapid and real-time health evaluation of post-earthquake structures as it is critical to distinguish which structures are inhabitable and serviceable and which are damaged and unavailable anymore. However, current evaluation methods are labor intensive, time consuming, and not cost effective.
