USGS-Recorded Earthquakes
We receive information in real time from USGS on earthquakes occurring in the Australia / Pacific region. The latest event can be accessed here once it has been received from USGS :Display latest USGS-recorded earthquake
We keep a copy ("mirror", >23/07/2007) of the details of earthquakes received from USGS. The list of all earthquakes is updated daily every 15 minutes. Click here to display it :

Once you have chosen the year and month, just click on the line you are interested in to see all the details of the earthquake.
Station Health
These messages only apply to IRD-connected stations (ie from which data can be gathered at any time). The meanings are as follows :This station has transmitted data within the last 48 hours: it is deemed to be operating normally.
This station has transmitted data within the last week, but not the last 48 hours: it is deemed to have a problem either with the connection or within the station itself.
This station has not transmitted data for over a week: it is deemed to be out of order.
If there are no messages displayed, it means the connection to our data server is temporarily unavailable. Please try again later. If the problem continues, you can report it to us using our contact form.

Seismic Activity in the South Pacific
Two seismic activity maps are available for the South Pacific :The first map shows all earthquakes occurring in the South Pacific since early 2007 as recorded by USGS. This map, produced using GMT, shows earthquakes as circles with diameters reflecting magnitude. It has clickable areas for enlarging the zone required :
- Papua New Guinea
- New Caledonia and Vanuatu
- Fiji and Tonga
- Wallis & Futuna (Horne Islands) and Samoa
- Kermadec
- New Zealand

The second map is of local and regional seismic activity. It shows events recorded by our stations (IRD velocimetric stations and RAP accelerometric stations) since 2007 (currently being updated). With regard to events also recorded by USGS, pinpointing may vary depending on earthquake locations and the stations that took part in detecting them.
WARNING : as we are currently working on velocity models, THIS MAP IS ONLY PROVIDED FOR THE SAKE OF ILLUSTRATION. An extra station will help improve seismic event locating. For the time being, we are unable to determine magnitude or mechanism in the event focus. These will appear in the meantime as single-size circles. Once you have enlarged a zone, you can return to the main map by holding down the Alt key and pressing the left arrow key (←).

Seismology Bulletin Format
These are provided in NORDIC (ASCII) format commonly used by the scientific community, or for printing purposes, in Postscript® format. The file for the current year or month is updated as soon as the data have been processed.Available Networks
CAVAScope : data and bulletins available for 1993 to 1998; NCVAN (New Caledonia – Vanuatu joint network): data and bulletins available since 1997 from permanent stations in the Cavascope network that are still operating.Currently: DZM, PLG, BKM, DVP (PVC is pending re-installation);
RAP (New Caledonian Permanent Accelerometric Network): only the bulletins are available on this site. RAP has been operational since January 2007.
