Piton de La Fournaise - 09.09.2022 / 04:50 UT - Camera Partage / OVPF - one click to enlarge

Following the seismic crisis of September 7, seismicity is still recorded under the summit area of ​​Piton de La Fournaise. However, since 9 a.m. (local time) today, the seismicity rate has decreased sharply with 1 low magnitude earthquake (< 0.5) per hour.

At the same time, the inflation (swelling) of the volcano, observed since the end of the last eruption on January 17, 2022, continues. This testifies to the continued replenishment of the superficial reservoir (located 1.5-2 km deep) by deeper magma. But since the end of the seismic crisis yesterday, and the end of the magma intrusion, no movement of magma from this reservoir to the surface is to be noted.

The recharge process from the depths to the superficial reservoir can take several days to several weeks before the roof of the reservoir weakens again and ruptures, thus giving rise to a new injection of magma towards the surface, but can also stop without giving rise to an eruption in the short term.

 

The volcanological observatory of Piton de la Fournaise (OVPF) having reported the decrease in the seismicity rate and a residual activity of low magnitude since this morning, the prefect of Reunion has decided to return to the VIGILANCE phase of the device. specific ORSEC* of the Piton de la Fournaise Volcano from Friday September 9, 2022 at 8:00 a.m.

The ban on public access to the upper part of the Piton de la Fournaise enclosure is therefore lifted from Friday September 9, 2022 at 8:00 a.m. with restricted access conditions.

Mitake crater eruption continues on Suwanosejima, in the northern Ryukyu Islands.

On September 8, the JMA reports an explosion, with a white plume 2,000 meters above the crater.

Today, September 9, another explosion occurred, accompanied by a gray plume at 1,600 meters.

A moderate eruptive activity continues at Ebeko.

According to visual data from Severo-Kurilsk volcanologists, explosions sent ash up to 2.6 km a.s.l., an ash plume is drifting north-northeast from the volcano.
This moderate eruptive activity of the volcano continues. Ash explosions up to 6 km (19,700 ft) above sea level could occur at any time. Ongoing activity could affect low-flying aircraft and Severo-Kurilsk airport.

The aviation code remains at Orange
