Did Adelaide just have a earthquake? I took this 14 stories up in the city. 😬😬😬 #earthquake
Today's Mansfield earthquake in Victoria as recorded on the seismograph in Government House, Adelaide. I clearly felt the vibrations at my desk in the Geological Survey of South Australia in Adelaide CBD.
AusArray SA seismic squiggle harvest time in the WPA, South Australia. Thanks to Col Telfer from the @AusAirForce for the drone footage. @DEM_sagov @AuScope @GeoscienceAus
Reduction in human-related seismic vibration (industry, planes, trains, automobiles,...) during the South Australian lockdown evident at AuScope seismic station GHSS located in Government House, Adelaide. Scale is nanometers (nm). Data processed & plotted using SeismoRMS.
Late to the party, but... sonic boom from Hayabusa-2 capsule re-entry above South Australia as captured on four GSSA AusArray SA seismic stations @DEM_sagov @AuScope @GeoscienceAus @AusSpaceAgency @haya2e_jaxa
Just finished the first service run of the GSSA's AusArray SA seismic network with @kate_selway and Bruce and Ann Goleby. Let's see what the data reveal... @DEM_sagov @AuScope @GeoscienceAus
The Geological Survey of South Australia deployed the AusArray SA broadband seismic array over two weeks in October 2020. Two vehicles, with a cumulative 10,000+ km covered. Phew! Thanks to @AuScope and @GeoscienceAus for the instruments @DEM_sagov
