We analyze slowness and azimuth anomalies, as recorded in the French Polynesia Seismic Network. The network can be considered as an array in its whole, or can be split into two subarrays, 350 km apart. In the former case, it is found that, contrary to Canadian VASA results, no anomaly is apparent for rays bottoming under Hawaii. In the latter case, a model of the crust is attempted under Tahiti as well as under the atoll of Rangiroa.
