Nineteen ninety-three was a particularly quiet year for Australian earthquakes, only 59 events had a magnitude of ML 3.0 or more. No damaging earthqakes occurred in Australia and the largest at Tennant Creek in the Northern Territory, had a magnitude of ML4.8. The Tennant Creek earthquake sequence which began in 1986 continued its prolific although declining activity. Intensity questionnaires were distributed for small four earthquakes and isoseismal maps prepared for the events at the Gold Coast, Borumba Reservoir and Lady Elliot Island in Queensland and Willunga in South Australia. A swarm of small earthquakes occurred near Mukinbudin, 250 km east-north-east of Perth in Western Australia. The swarm was similar to others that have occurred in earlier years throughout the wheatbelt. Recordings of strong motion data were also sparce and none of them were of direct engineering significamce with only two earthquakes of magnitude ML > 2.9 triggering accelerographs. The highest acceleration recorded was 1260 mmls/s from a magnitude ML 2.7 earthquake at a distance of 0.5 km. Worldwide there were 13 major earthquakes, the largest with a magnitude of Ms 8.0 occurred south of the Mariana Islands on 08 August. No one was killed however 48 people were injured on Guam. The most devastating earthquake was an intraplate earthquake of magnitude Ms 6.3, which occurred in peninsula India near Latur and Killari on 29 September killing 9748 people. Several hundred people drowned when a large tsunami swept the Japan Sea following an earthquake in southwest Hokkaido and several other tsunamis were recorded. World-wide, more than 10 100 people died in earthquakes in 1993, compared with 2880 and 2800 in 1992 and 1991 respectively. The average for the century is about 10000 per year. During 1994, a single underground nuclear explosion was detonated; by China at the Lop Nor test site on 7 October. Other nuclear weapons States abided by a self-imposed moratorium on testing in recognition of the changed international political climate.
