The ARC-VANUATU project was conducted between May 2008 and February 2009 using 20 onshore seismometers and 10 OBS. A total of 40,430 events were recorded. Arrivals were picked using an automatic picking routine program (Baillard et al., 2014) and 31,065 events were localized using a 1D velocity model (Baillard et al., 2015).
Earthquake locations and 1D velocity model were used to calculate 3D P and S velocity models with the LOTOS software (Foix et al., under review). The new 3D velocity models were used to locate the original catalog (composed of 40,430 events) with the Non-linear, earthquake location (NLLoc) program (Foix et al., under review). NLLoc located 10,486 events within an inversion box of 290x290x103 km3 and the forearc.

The ARC-VANUATU seismology network, deployed between May 2008 and February 2009, was composed of 20 land stations and 10 Ocean Bottom Seismometers (OBS) over the central Vanuatu forearc region.
Seismological data are available at through http://dx.doi.org/10.15778/RESIF.3A2008
Archives stored here are composed of 1) the ARCVANUATU earthquake catalog located using a 1D velocity model (ARCVANUATU_1D.cat),
2) the 1D velocity model and station coordinates used for these earthquake locations (STATION_MODEL1D.HYP),
3) the ARCVANUATU earthquake catalog located in a 3D velocity model (ARCVANUATU_3D.hyp), and
4) the 3D velocity model used for these earthquake locations (Model_3D_NLLoc).
