The 1954 Adelaide earthquake had its center at Darlington, some 12 km (7.5 mi) to the south of Adelaide in South Australia. It took place at 03.40 in the early morning of 1 March 1954 and had a reported magnitude of 5.6. The quake is thought to have started along the Eden-Burnside fault line, which is essentially the Hills face zone, at a depth of 4 km although, due to lack of instruments, this is uncertain.
