The Salt Lake City metropolitan area is one of the most seismically hazardous urban areas in the interior of the western U.S. because of its location within the Intermountain Seismic Belt and its position adjacent to the active Wasatch fault. The elapsed time since the last large earthquake on the Salt Lake City segment of the Wasatch fault is approaching the mean recurrence interval based on the short-term paleoseismic record. In order to help raise the awareness of the general public and to help reduce earthquake risk in this area, we have developed nine microzonation maps showing surficial ground-shaking hazard. The maps are GIS-based and incorporate the site response effects of the unconsolidated sediments that underlie most of the metropolitan area within Salt Lake Valley. These nine maps, at a scale of 1:75,000, make up three sets, each consisting of three maps that display color-contoured ground motions in terms of (1) peak horizontal acceleration, (2) horizontal spectral acceleration at a period of 0.2 sec (5 Hz) and, (3) horizontal spectral acceleration at a period of 1.0 sec (1 Hz). One set of maps consists of deterministic or “scenario” maps for a moment magnitude (M) 7.0 earthquake on the Salt Lake City segment of the Wasatch fault. The two other sets are probabilistic maps for the two return periods of building code relevance, 500 and 2,500 years.

During his career Douglas Wright established himself as New Zealand's leading contemporary dancer and choreographer. He started out with the Limbs Dance Company in 1980, then worked in New York with the Paul Taylor Company and DV8 Physical Theatre in London before forming the Douglas Wright Dance Company in Auckland in 1989. During this time he created over 30 major dance works, which culminated in his 2006 masterpiece 'Black Milk', his last major work. The dance critic Jennifer Shennan wrote, 'In my opinion, this is Wright's, New Zealand's, and dare I say it, the world's finest choreography. I dare.' Black Milk is a permanent record of this extraordinary piece of dance theatre, built largely around the remarkable images of Auckland photographer John Savage. When seeing these images Douglas Wright commented: When I saw John's first pictures of a performance I felt that here, for the only time in my experience in photography, someone had managed to capture the breathless sorcery of live dance-theatre without pulling its wings off.
