Depth to the Juan de Fuca Slab Beneath the Cascadia Subduction
... Few data are available to constrain the slab geometry below a depth of about 50 km. This deeper region is poorly resolved in wide-angle experiments. Seismicity is typically used to map the Wadati-Benioff zone of subduction systems elsewhere, but is quite sparse for the Cascadia subduction system. We ...

Earthquake casualty estimation
Recent advances are improving the speed and accuracy of loss estimates immediately after earthquakes (within less than an hour) so that injured people may be rescued more efficiently. After major and large earthquakes, rescue agencies and civil defense managers rapidly need quantitative estimates of the extent of the potential disaster, at a time when information from the affected area may not yet have reached the outside world. For the injured below the rubble every minute counts.To rapidly provide estimates of the extent of an earthquake disaster is much less of a problem in industrialized than in developing countries. This article focuses on how one can estimate earthquake losses in developing countries in real time.
