Summary: Seismicity rate before eruptions on Piton de la Fournaise volcano: Implications for eruption... are difficult to foresee using daily seismicity at Piton de la Fournaise (PdlF) volcano, except within a few... eruptions in the 19882001 period, we find that the seismicity rate increases 2 weeks before the eruption |
