It reached a Richter magnitude of 5.5 and caused significant structural damage in a wide area.Cooney G. H. The New South Wales Earthquake of May 22, 1961 Australian Journal of Physics 8 January 1962 15 4 1962AuJPh..15..536C 10.1071/PH620536 536–548 free The earthquake was felt from the Snowy Mountains region in the southeast of the state to Newcastle on the coast about 75 mi -1 north of Sydney; to Dubbo in central eastern NSW about 180 mi -1 northwest of Sydney; and to Narrandera in the state's central south about 210 mi -1 southwest of Dubbo – an estimated area of 50000 sqmi -1. In the area of Moss Vale, Robertson, and Bowral about 70 mi -1 southwest of Sydney, the earthquake caused significant structural damage to buildings, while rockfalls blocked the nearby Macquarie Pass. Sydney suffered minimal damage from the earthquake itself, though the tremors and resulting power failures caused "considerable alarm". Seismograms at the Sydney suburb of Riverview were used to estimate the magnitude of the earthquake. There were only three known earthquakes of comparable magnitude prior to this one, occurring in 1930, 1934 and 1938.
