PORTLAND, Ore. — A loud explosion, crumpled buses and cars and dozens of victims lying on the ground with authentic-looking injuries lent an air of reality to a major terrorism exercise that took place Tuesday at the Portland International Raceway, and at locations across Portland.

Compounding the realism was a cold, steady rain that made the ground slick and tested sensitive electronics equipment.

The city of Phoenix, Ariz., and the island of Guam are also taking part. The largest part of the drill, called TOPOFF 4, is taking place in Portland.
