You think right, alright. LOL If there was anything in Pat Robertson's magical God-slur against Haiti then yeah you might think Australia's fires covid and floods really meant the cranky ol' man up there had a thing against us. If so though he would have more against you guys. We don't get tornadoes as you do. Earthquakes, mostly only shivers

Why do we get earthquakes in Australia?

The Australian plate is the fastest moving continental land mass on Earth and is colliding into the Pacific plate to Australia's north and east, and the Eurasian Plate to the northwest. This generates mainly compressive stress in the interior of the Australian continent, which is slowly building up across the plate as it moves northeast about 7 cm per year. Australia's earthquakes are caused by the sudden release of this stress when rocks deep underground break and move along a fault line. While some parts of the country are more likely to experience earthquakes than others, large earthquakes can occur anywhere across the continent, and without warning.

On average 100 earthquakes of magnitude 3 or more are recorded in Australia each year. Earthquakes above magnitude 5.0, such as the destructive 1989 Newcastle earthquake, occur on average every one-to-two years. About every ten years Australia experiences a potentially damaging earthquake of magnitude 6.0 or more such as the magnitude 6.5 Meckering earthquake in October 1968.

A short animation showing earthquakes occurring in Australia during 2014, presented as a timelapse.
2014 was a relatively quiet year for Australian earthquakes. Most earthquake events measured less than magnitude 4, which is considered small and unlikely to cause damage.
P - Only seven earthquakes in 2014 were magnitude 4.0 or larger and these were felt throughout the regions in which they occurred. Although Australia, on average, tends to get one magnitude 5 per year, no earthquakes magnitude 5 or greater occurred in 2014.

Agree the view was a treat just i am attracted to looks in faces too. Now we both know who Sydney is. Must say her professionalism was impressive. ;-)
