There are a handful of news articles suggesting that the #Broome#earthquake is the largest recorded in Australia, or the largest in WA.
Magnitude is a funny thing and the Broome event wasn't the largest in Aus or WA (thread)
To get a good location, depth and magnitude for a quake, we need nearby seismometers
Australia got its first permanent seismometer in Perth in 1901 (WA areleaders in earthquakes!)
By 1955 there were only FIVE permanent seismometers in the whole country!

A paper I'm really proud to co-author recently got published in JGR! (doi.org/10.1029/2019JB…)
We produced 168 (!) CSC models to test what scenarios rupture all 7 faults involved in the 2010 Darfield NZ earthquake (and hence, what scenarios create larger earthquakes) [thread]
The Darfield earthquake was a magnitude 7.1, and it ruptured across seven (known) faults. It created a surface rupture on the Greendale Fault (pictured), but seismological data shows it started on the Charing Cross Fault
