Seismology

A small number of ASSA Members have become interested in recording seismic activity (Earthquakes) as part of their adventures into 'Earth Sciences'.

They, along with other like minded people across Australia, have formed 'The Seismological Association of Australia Inc' (SAA). On the following pages are some of the things and information about what we, the SAA do.

 

On behalf of the SAA and its members, I'd like to thank the Astronomical Society of South Australia for 'hosting' our website and Phil (ASSA's web master) for his ongoing assistance.

Blair Lade, Chairman of SAA

 

 

 The devastating magnitude 7.5 earthquake in PNG 28th Feb 2018 recorded at THS, a site near Modbury Heights in South Australia.

2 mag 4 aftershocks are clearly visible on the above seismogram.

Everyone in our 'network' recorded the last North Korean nuclear blast on their instruments.

We also deploy portable seismic recording instruments in temporary installations in regions where seismic activity occurs.

All of our data goes into the Australian seismic data bases and is available at no cost to researchers and other interested people world wide.

 

SAA's Chief Seismologist David Love and Chairman Blair Lade deploying a portable solar powered instrument at Yongala SA during a seismic 'swarm' in September 2011. About 200 seismic events were recorded and analysed to produce 'focal mechanisms' from this swarm. One of the locals we spoke to during the deployment said she could feel the larger events and could hear lots more.

 

Data recorded by our instruments is automatically sent via the internet to

A really good link about charging batteries, I've put this in because we use a LOT of batteries throughout our network.

Want to run your own seismic station? Then have a look at Raspberry Shakes, a seismic recording system based around the Raspberry Pi with an add on board. You can also send your data to us!
