Manually collected volcano data have been migrated from FITS to Tilde and are available through the API and Data Discovery application. You will need to start using Tilde to access this data by 31st March 2024 when we deprecate manually collected volcano data in FITS. Information on how an existing FITS query should be written for Tilde is available on Github. If you have questions, please email us at including in the subject "FITS to Tilde migration".

GeoNet API

Welcome to the FITS API.

The GeoNet project makes all its data and images freely available. Please ensure you have read and understood our Data Policy and Disclaimer before using any of these services.

The FITS API provides access to the observations and associated meta data in the Field Time Series database. If you are looking for other data then please check the full range of data available from GeoNet.

The following endpoints are available:

API queries may be versioned via the Accept header. Please specify the Accept header for your request exactly as specified for the endpoint query you are using.

If you don't specify an Accept header with a version then your request will be routed to the current highest API version of the query.

Taking advantage of the API versioning will pay dividends in the future for any client that you write. We use the jq command for JSON pretty printing etc. A curl command might look like:

curl -H "Accept: application/vnd.geo+json;version=1" "http://...API-QUERY..." | jq .

You may also be able to find a browser plugin to help with setting the Accept header for requests.

The response for a query can be compressed. If your client can handle a compressed response then the reduced download size is a great benifit. Gzip compression is supported. You can request a compressed response by including gzip in your Accept-Encoding header.

The code that provide these services is available at If you believe you have found a bug please raise an issue or pull request there. Alternatively contact us detailing the issue.
