In the Cities Project Perth, GA is developing a multi-hazard risk assessment of the Perth metropolitan area. One of the main objectives of the Project is to develop an earthquake hazard and risk model for this area. The hazard model is developed using informaiton about earthquakes, the geology and the local soil characteristics of the region. As part of this process, we will develop several earthquake scenarios with events originating at specific locations in the region. To define an appropriate model of seismicity, the Cities Project initiated an expert debate to discuss and to formulate geological and seismological parameters for the Southwest Seismic Zone and the area around Perth. The debate was followed by a workshop in December 2002 in Canberra where the seismicity model of SW WA was ultimately defined. Further discussion was held following the workshop, culminating in an agreed seismicity model for the region.

The Australian Seismological Report 2010 provides a summary of earthquake activity for Australia for 2010. It also provides a summary of earthquakes of Magnitude 5+ in the Australian Region, as well as an summary of Magnitude 6+ earthquakes worldwide. It has dedicated state and territory earthquake information including: largest earthquakes in the year; largest earthquakes in the state; and tables detailing all earthquakes detected by Geoscience Australia during the year. There are also contributions from PIRSA describing Seismic Networks and providing Earthquake locations for South Australia.

The year was another marginally below average one with respect to the frequency and magnitude of earthquakes in Australia; there were two of magnitude 5 or more but no large earthquakes of magnitude 6 or more. It was an above average year for major earthquakes worldwide with one great earthquake of maptude M 8.2 and 16 of magnitude M 7.0 or more.

The recording of continuous waveform data presents different challenges to the recording of event triggered segmented data or to the recording of semi-continuous yet offline data. Many formats in use today derive their origins from the earlier imperatives of such systems. This article will briefly classify such formats so as to better appreciate continuous format requirements. Following this a comparison will be made of continuous formats and the format adopted for use in the Australian National Seismic Network (ANSN). The CD 1 format in detail, its use and adaptation within the ANSN will come after this. Some contextual background on networking will be provided and this will then be wrapped up by a section on where the ANSN may go in the future with CD 1. An appendix is provided to explain data conversion on the GDAS system.
