OCCAM VLBI Processing Software FTP site Geodetic Very Long Baseline Interferometry (VLBI) observations provided the first direct confirmation of tectonic plate motion at the end of the 1980s. Now VLBI observations measure the motions of stations with accuracy better than 1mm/year together with other space geodetic techniques such as Global Positioning System (GPS) and Satellite Laser Ranging (SLR) Analysis.

The earthquake mapping tool allows you to: * view recent earthquakes which occurred over the past 30 days * search and explore all Australian earthquakes * search and explore earthquakes worldwide * view seismograms of earthquakes over the past 90 days * advise Geoscience Australia when you have felt a recent earthquake.

If you felt an earthquake, or know of an earthquake that occurred recently, please fill in this form. Even if you did not feel the earthquake yourself, please fill in the form, as this information will assist us.

AUSGeoid98 is the current model in a series of national geoid models for Australia produced by Geoscience Australia. It replaced AUSGeoid93 and uses the latest available data and techniques.

Natural hazards have an impact on every Australian State and Territory. These hazards include bushfires, cyclones, earthquakes, floods, landslides, severe weather, tsunami and volcanoes. These phenomena threaten lives and damage private and public assets, as well as disrupt water, power, transport and communication services. These hazards and their associated impacts also can seriously affect employment, public administration and incomes to industry, agriculture and commerce.
