Ivy Mike in Six Archival Images: Before and After Elugelab

The labeled aerial photograph locates Elugelab among neighboring islands before Mike. The atoll’s inhabitants had already been relocated to Ujelang. What looks like a set of small shapes on a military photograph was part of a lived landscape. The final image in this gallery records the same area after the explosion.

The Mike installation required a substantial building and supporting equipment. Its scale helps explain why the successful test did not immediately provide a compact operational bomb. This archival view records the experimental apparatus before detonation; it is included as a historical photograph, without treating the machinery as a construction diagram.

A high-speed photograph catches the early fireball. The image belongs to the scientific recording of the test, when cameras could reveal stages too brief for an observer to distinguish. Its archive date is often October 31 because of the time difference; the explosion took place on November 1 at Enewetak.

The Mike cloud rises above the Pacific after the 10.4-megaton test. This color photograph became one of the best-known images of thermonuclear testing. The distant view gives the cloud a clear outline while concealing what happened at ground level: the destruction of Elugelab and the contamination left across the testing landscape.

A dark circular crater occupies the place where Elugelab appeared in the pre-test view. The surrounding islands provide a way to compare the two photographs. This is the lasting geographical change behind the spectacular cloud: an island removed from the atoll, within a testing program whose consequences continued long after 1952.
