A SITE SPECIFIC AND REMOTE MACHINE BASED INTERVENTION IN THE REGION OF MECKERING, WESTERN AUSTRALIA, 2004D V Rogers
The Meckering Earthquake was located in a well-documented zone of seismic activity which is the most active region of Australia. This region is centred about 150 kilometres east of Perth and is known as the South-West Seismic Zone (SWSZ) and measures roughly 300 kilometres by 500 kilometres. According to Geoscience Australia (AGSO), more than 12,000 earthquakes have been recorded in the area since September 2001 with most of these events being aftershocks of larger events.
The principal fault scarp of the Meckering earthquake is nearly 37 km long, aligned approx N-S, and had a maximum observed vertical displacement of 3.5 metres. Trenching across this scarp took place in 1990, and it was concluded that the Meckering earthquake was the result of the reactivation of an old fault line, possibly tens of thousands years old.
The proposed work involves identifying an appropriate site along the Meckering principal fault scarp and with plant equipment re-landscaping a selected and surveyed site. It is integral that the bottom of this sloping pit will be below the level of the land and ideally if possible below sea level. An earthquake simulator will then be placed on site and operated autonomously for a minimum period of approximately three months. The site will be made accessible to the general public and visitation to the actual site will be encouraged, located approximately 135km form Perth and 70km from Kellerberrin. (See Map Below)
Conceptually the work is a non-site feedback loop between machine control and the actual site of generated tectonic displacement. Primarily the work will be presented via the WWW with realtime video and audio dissemination, daily journal logs and current updated earthquake event logs. It is assumed that a body of resulting documentation will be exhibited after the intervention within a gallery context.
The near-realtime data feed for the control of the earthquake simulator would be supplied from either one or both of the following two sources;
1. Globally monitored seismic data collected by the USGS.
2. South-West Seismic Zone data (Local Area) collected by Geosciences Australia (formally AGSO)
Inherently the work is fraught with many logistical hurdles of which several possible partners have been identified to make the work possible.
