Eastern Victoria Geoscience Initiative

The Geological Survey of Victoria (GSV) conducted a low impact regional deep seismic reflection survey in eastern Victoria, during March and April 2018.

For about two months a convoy of trucks moved slowly through the region along two survey routes:

  1. Starting south of Benalla and travelling approximately 306 kilometres eastwards towards Tom Groggin and into New South Wales.
  2. Starting north of Benambra and travelling approximately 215 kilometres south eastwards near Bendoc and into New South Wales.

The survey travelled along public roads, across private properties, Crown land and through national parks. GSV scientists and officers worked closely with regional stakeholders and land owners about the project and the survey.

The survey passed through and nearby locations include Molyullah, Edi, Merriang, Rosewhite, Kancoona, Eskdale, Upper Gundowring, Runny Creek, Ovens, Myrtleford, Benambra, Wulgulmerang, Wulgulmerang East, Deddick Valley and Bendoc.

The deep seismic reflection technique did not cause any damage to the land. The data from the survey will allow geoscientists to interpret rock formations and faults to a depth of about 50kms into the earth’s crust.

The data collected will be processed by specialists over several months prior to public release in 2019 unless completed sooner.

The survey is part of a long-term program to build knowledge of Victoria’s geological architecture and will focus on rock types, faults and their distribution.

This is the third such seismic reflection survey conducted by the GSV. Two previous deep seismic reflection surveys were conducted in 2006 and 2009 in central and western Victoria respectively.

The survey lines have now been completed. The survey covered over 511km in Victoria.

Regional TV stations Nine Border North East and Prime7 took up our invitation on Friday 9 March to report on the Geological Survey of Victoria's seismic survey in north-east Victoria for their evening news bulletins.

The Prime7 story is on the station's Facebook page. Please click on the link to view the story as it was broadcast on that evening's news.

Planning is currently underway for a ground gravity survey to be undertaken by the Geological Survey of Victoria along the seismic survey route in 2018. The gravity survey is far less intensive than the seismic survey and will be completed in significantly less time. Updates regarding the timing and progress of the gravity survey will be published here over the coming months.
