A real-time procedure has been set up to select and relocate relatively similar events recorded by the U.S. Geological Survey Hawaiian Volcano Observatory (HVO, Hawaii) seismic network at the Observatory. It allows the relocation of such similar events with an uncertainty whose order of magnitude is 50 m horizontally and 100 m vertically. As a first step, a systematic exploration of the volcano to find similar events within the seismicity recorded between years 1988 and 2000 has been undertaken and allows events to be gathered into large multiplets. A generalized relative relocation of these similar events has been performed, and a database has been built from the result of this relocation. Incoming earthquakes are routinely compared to this database and relocated, and the database is updated. Preliminary results are presented and discussed.
