For a few days we have recorded a slight change in the activity of Piton de la Fournaise with:
– the resumption of inflation at the level of the summit zone at rates comparable to those recorded before the eruptions of 2015 and after the eruptions of 2016;
– a slight summit seismicity (2-3 events per day) accompanied by some deep earthquakes;
– high concentrations of CO2 in the soil at the level of the volcano deposit.
This shows that deep magma is still present and that the « Vigilance » phase remains in place.
Nevertheless, as has been observed several times this year, such phases of inflation recovery and seismicity may stop very quickly and not result in a medium-term eruption.
