Return to the vigilance phase and restricted access to the upper part of the Enclos at Piton de la Fournaise from Wednesday 23rd to 20h00.

The ban on public access to the upper part of the Piton de la Fournaise enclosure has been lifted.

Access to the upper part of the enclosure is strictly limited to two marked trails:
• the Pas de Bellecombe - Formica Léo trail - Rivals-Caubet crater trail;
• the Pas de Bellecombe trail - Formica Léo - access trail to the Dolomieu crater observation site (access from the north of the crater).

 

Inflation (swelling) of the volcano, observed since October 11 continues. This testifies to the continuation of the recharge of the superficial reservoir by deeper magma. The probability of a fifth eruption for this year 2019 is still relevant.

To wait, a video on the 2007 eruption ...

Back on the eruption of La Fournaise in 2007 - Video University of Reunion / Vulcania.

From 22:20 UTC 23 October, ash in small quantities began to be observed in the gas and steam emissions of Klyuchevskoy.

According to KVERT, the ash would come from an effect of erosion of the walls of the pipe by the high gas emissions ... it is not a new eruption. The plume rises to 5.500 meters asl.

The aviation code was raised to yellow, then to orange on 24 October at 01:20 Z.

In Kilauea, the crater lake of Halema'uma'u continues to grow; its level is measured on October 19 at 608 meters under the observation site. The steam that sweeps its surface testifies to the high temperature of the water, and the winds at the bottom of the crater. The refill is marked by areas of bluish color on a general tint of the surface of greenish yellow color.
