reported near midnight in Kalgoorlie, which resulted in an underground rock fall, killing one miner and injuring several others. Also in the 1990s further seismic activity required consideration of seismic activity. Meeberrie Station 1941 The second largest onshore earthquake to date in Western Australia was on 29 April 1941 at Meeberrie station at 01.35.39 am (Lat −26.90 and Long 115.80). It was initially reported with a magnitude of 7.3 (though some sources give 7.2) but was revised to 6.3 in 2016. Yallingup 1946 On 20 April 1946 a magnitude 5.7 earthquake occurred near Yallingup at 9:13pm on 19 April 1946 (5:13 local time on 20 April), which was felt at Kirup. A tremor was reported at 5:30am at Caves House Yallingup and at Busselton on 30 April, which is probably the same event, reported on the wrong date. Gabalong 1955 Gabalong, 30 August 1955, magnitude 5.8 Gabalong, a small community about east of Moora and NNE of Perth. The earthquake, at 9:52pm local time, was felt at MM VI at Yericoin and Miling, and MM V in Moora. It was felt in Perth at intensities between MM II and MM IV, and at Dongara at MM II. It was preceded by a magnitude 5.3 earthquake at the same location at 2:09pm on the same day. It was a SouthWest Seismic Zone earthquake, and because of the poor location capabilities at the time, may well be related to a series of earthquakes near Yericoin, which started with a magnitude 5.1 earthquake on 2 May 1949. Busselton 1959 A magnitude 5.0 earthquake occurred at 12:07 GMT on 3 October (8:07pm local time) at 34.5 degrees south, 114.5 degrees east. It was felt at Busselton, Yallingup, Margaret River, Bunbury, Cape Naturaliste and Cape Leeuwin. Near Brookton 1963 18 January 1963 at Nourning Spring, approximately NE of Brookton and approximately ESE of Perth. It was felt at Intensity VII at Nourning Springs, VI at Brookton, and MM II at Perth. It occurred at 1:49pm local time, and had a magnitude of 5.4, although it was given a magnitude of 4.9 originally. Many earthquake questionnaires were distributed for this event, and a good isoseismal map was prepared. Meckering 1968 On 14 October 1968 at 10:59am, an earthquake registering 6.9 on the Richter scale occurred east of Perth in Meckering, Western Australia. Injuring 20 people, causing over 2 million dollars in damage and felt in towns
