AUSTRALIAN EARTHQUAKES:
CAN EAST AND WEST SEE EYE TO EYE?

David Love
Seismological Association of Australia


     While science and seismology advance, there are still differences that seem to be ingrained, stopping us seeing things from another point of view. While I am asked regularly about fault lines, we have yet to find in Australia one geologically mapped fault that has earthquakes occurring along it. When it comes to earthquake hazard, most engineers and regulators like smoothed maps without sharp changes, but seismologists like their favourite bullseye.  However there is a model of earthquake occurrence that is just in the development stage in Western Australia that looks more like chicken pox.  Will it turn out to be useful?  When it comes to recording across Australia, there has been a tendency to spread recorders out in a grid fashion to measure systematically, and model deep structure.  On the other hand, there is the storm chaser, always wanting to get his recorders right on top of the action.  He wants to know about the earthquake.

     We will look at these divergent views, and also some earthquakes during the last year from east and west:  Woods Point (Vic) ML5.9, Murrayville-Pinnaroo ML5.1, Mount Barker ML3.7 and Arthur River, WA ML4.8.  The quest to learn more continues.

     David Love studied at the University of Adelaide, gaining a BSc Hons in Geophysics.  He began working with the SA Dept of Mines in 1980, working in gravity and magnetics.  He was shifted to earthquake monitoring in 1986 'until an expert was appointed'. He was involved in Australian Standards for earthquakes from 1988 to 2007. He continued monitoring until the state government network was closed in 2017, and the Seismological Association of Australia formed.  He now continues monitoring with the SAA.

Upcoming Workshop

Cynthia Pyle will run a workshop before the August meeting.
The topic for the August workshop will be “TBA”. 

The workshop will start at 6.30 pm, but people are welcome to come in later, as everyone
works independently or with a friend.

The workshop will be held in the Sprigg Room. Go past the Tate Museum and take the next
staircase on the right. The Sprigg Room is right at the top of the stairs. 
Anyone who arrives after 6.30pm and can't get into the building can ring the FGC bell if it is in place.


 

10 Minute Topic

The 10-minute talk will be: “Beach dynamics” by Laurence Campbell.
