Piton de la Fournaise volcano (La Réunion): sudden drop in tremor / lava effusion - possible end of eruption

Images of lava bubbles from the main vent on 12 Oct (OVPF)
After a the eruption had intensified considerably during the past week, tremor suddenly dropped this morning at 08:02 local time and only showed sporadic pulses. The lava effusion seemed to have stopped as well. Aerial surveys this morning showed no more lava inside the vent.
Tremor evolution up until yesterday (OVPF)
Whether this is a temporary pause or a rather sudden (but not uncommon) end of the eruption will be clearer in the near future.
Up until yesterday (17 Oct), the eruption had been increasing, and generated again lava fountains from the main vent up to 40 m tall. The main vent itself had increased to reach approx. 100 m diameter, containing a lava lake which released large bubbles of gas (SO2), generating spectacular lava bubble ejections (images).

The current, remarkably long-lived eruption continues with no signs of weakening. On the contrary, a significant increase in tremor and lava effusion was noted starting 12 Oct, reaching high values comparable to the start of the eruption. The observatory estimated the effusion rate to have risen from 9 to 13.5 cubic meters per second. ... [meer...]

The eruption continues with little changes overall. The lava flow field gradually expands (and thickens) towards the southeast from the vents, with the most distant flow fronts now being around 2600-2700 m away. ... [meer...]

The eruption continues into its second month,- for Piton de La Fournaise's standards this is an unusually long-lived one. Accompanied by stable tremor, effusive activity remains strong and feeds a growing lava flow field that slowly expands towards the east in direction of the Grandes Pentes. ... [meer...]

The eruption continues at weak intensity. As of yesterday, only one vent, a cone about 20 m high, remained active producing pulsating fountain-like strombolian explosions of bursting lava bubbles that reach 15-20 m height. ... [meer...]

The eruption that began last Monday continues. Lava output is much lower now (approx 10 cubic meters / second) than in the beginning (30 cu m/s), but more or less stable. ... [meer...]
