What event measured a 5.6 on the Richter magnitude scale and led to the establishment of the New South Wales Urban Search and Rescue Task Force 1?
1989 Newcastle earthquake The 1989 Newcastle earthquake occurred in Newcastle, New South Wales on Thursday, 28 December. The shock measured 5.6 on the Richter magnitude scale and was one of Australia's most serious natural disasters, killing 13 people and injuring more than 160. The damage bill has been estimated at A$ 4 billion (including an insured loss of about $1 billion).
1946 Vancouver Island earthquake The 1946 Vancouver Island earthquake occurred with a moment magnitude of 7.5 that struck Vancouver Island, on the Coast of British Columbia, Canada, at 10:15 a.m. on June 23. The main shock epicenter occurred in the Forbidden Plateau area northwest of Courtenay. While most of the large earthquakes in the Vancouver area occur at tectonic plate boundaries, the 1946 Vancouver Island earthquake was a crustal event. Shaking was felt from Portland, Oregon to Prince Rupert, British Columbia. This is one of the most damaging earthquakes in the history of British Columbia, but damage was restricted because there were no heavily populated areas near the epicentre, where severe shaking occurred.
