The Zones Project 2020

What if a one megaton nuclear bomb hit downtown Portland?

This project describes the effects of a one megaton nuclear weapon, 50 times as powerful as the one dropped on Hiroshima, Japan on August 6, 1945. For illustrative purposes, we have created a map to show the effect if ground zero were the middle of the Burnside Bridge in Portland, Oregon.

Most nuclear weapons owned by the United States and other nuclear powers are much stronger than the 20 kiloton bomb exploded in 1945. But on this 70th anniversary of the only military use of an atomic weapon (on a civilian population) we recall what happened in Hiroshima and in Nagasaki three days later.

Consider ways you can display these posters to remind people around the Portland Metro area of the grim reality of the world's nuclear nightmares. (Click on your zone to download an 8.5x11 poster; enlarge to 155% for 11x17.)
