The Great Quiet – 1959 to 1963

Sonic booms, large meteors, and fireballs—alongside corresponding mass cetacean strandings—had been documented regularly since modern Australian and New Zealand observation records began. Following an atmospheric entry event off the coast of New Zealand in March 1959, a significant multi-year hiatus occurred. For over four years, no major bolide events were recorded across the region. Concurrently, historical archives record no mass whale strandings in Australia or New Zealand during this interval.

After 1,585 days, this period ended on July 24, 1963, when a major fireball detonated over the Great Australian Bight. The acoustic shockwave was recorded across a vast distance, producing a detonation loud enough to be heard in Port Lincoln, over 100 km away, where observers likened the sudden acoustic impact to an exploding stove.

Simultaneously, observers at Eucla, Western Australia—over 700 km to the west—reported a luminous object larger than the sun descending toward the ocean, with local fishermen reporting an offshore marine impact. Two weeks later, a mass stranding of 59 False Killer whales (Pseudorca crassidens) was discovered approximately 9 km east of Eucla. The 1,585-day quiet period had officially concluded.
