Earthquake Monitoring Network Expansion
A new network is being established with funding from the Commonwealth Government (under the Natural Disaster Mitigation Program), SA Water, Primary Industries and Resources SA, and Security and Emergency Management Office.
A network of seven sites (two existing and five new) will record vibrations and send data in close to real-time to a central office where earthquakes will be quickly located. Within the metropolitan area, three instruments (probably moved annually) will be used to estimate amplification properties.
The expected completion date for new network is November 2006.
Monitoring Sites
Equipment at each site will include:
- Echo recorder by Environmental Systems and Services
- Strong motion sensor included in recorder
- Guralp seismometer (two sites broadband, others short period)
Network Details
The diagram below shows the locations of the proposed new stations (yellow circles). The locations are as follows:
- Adelaide (ADE)
- Freeling Area
- Myponga (MYP)
- Palmer (PLMR)
- Sedan (SDAN)
- Strathalbyn
- Yorke Peninsula
Also indicated on the diagram are the current stations (red triangles). For more information on the stations progress, visit the Station Progress Information page. View a higher resolution image here (.jpg file ~ 80kb).
Project Status - March 2007
Equipment Purchase
- All equipment has been received
Central Office
- Central computer is receiving near real time data. The example below shows the record of an earthquake of magnitiude 5.2 in Indonesia on the 13th of March, 2007.
