Hi Canie. Australia is using GPS to predict earthquakes. Should be interesting to see if it works. Take Care…Don in creepy town

“As the first step in this project, the researchers will install a Global Positioning System (GPS) station at each of the fifty ground locations in the South-West Seismic Zone.
GPS is a way of obtaining the position of geographical points on the Earth's surface and allows the position of the each station to be measured very precisely — to within a few millimetres, in fact. The team will measure each station's initial position as part of fieldwork in May. Then station positions will be measured again in two to five years, to allow movements large enough to be accurately measured by the GPS equipment.”

“The repeat measurements will allow Geoscience Australia to map the direction of any rock movement, and may show areas that are distorting the fastest — these areas may be prone to earthquake activity in the future. The South-West Seismic Zone is likely to be distorting by as much as two to five millimetres per year, a rate which equates with 20 to 50 centimetres in 100 years.”

“The information gathered will be used to better understand why earthquakes have occurred in this region and where they might occur down the track.”
