Seismic Waveforms

Please note that not all services are fully supported. We are moving to a fully supported FDSN service, which will replace CWB.

Extracting Waveforms

Waveform data from GeoNet's seismic, acoustic and tidal gauge instruments can be requested through the following services.

FDSN webservices


This will be our recommended and fully supported data access tool. At the moment however it is still under construction. Please test our beta service (all 3 services) or you can use our existing service which has some performance issues. For more information see the FDSN page.

Continuous Waveform Buffer (CWB)


Caution: This service has been supported in the past but will become deprecated as we move to a full FDSN service. We recommend you switch to using the FDSN webservice.

Fordetailed information please see the CWB information page.

Very Large Data Requests

If you need very large amounts of continuous waveform data please contact us for alternative methods to download data.

Real-Time Waveforms

SeedLink protocol is used by GeoNet to send waveform data in from the field stations to our data centres, and within our processing systems. GeoNet also runs a publicly accessible SeedLink server.

For information about the protocol please see the IRIS SeedLink Website.

If you would like to connect to our SeedLink server please contact us.
