How to download AusPass data for a selection of seismic events

- Step 2: In the "Stations controls" panel on the left of the screen, select the earthquake catalog of your choice using the "Catalog Service" dropdown menu.
- Step 3: Set the time period to search earthquakes. Only a few catalogs (USGS) provide data during the 1980s and 1990s. Unfortunately, all the catalogs are not always available. We found the USGS and GFZ catalogs quite reliable.
