Piton de la Fournaise-vulkanen is on the island of Reunion, about
200 km Southwest of
Mauritius, near the Republic of Malagasy. The volcano rises 2.631
m asl, and
it is the only active volcano on the island, but also one of the most
active in the world.
Piton is a basaltic shieldvolcano. It has built up in the Piton des
Neiges, an old volcano which
can be dated 22.000 years back.
Piton de la Fournaise have had at least 174 eruptions since 1640.

third flow has reached the ocean through the wood.
At 19:10 yesterday, the volcanologic network recorded a suddenly
remarkable fall of
trémors. In five minutes, the electroencephalogram became almost
flat, a situation which was
maintained to 23:00 h. One could thus regard the eruption as completed
Now it's just a question if Piton itself does agree....
After the appearance of a first cone on the littoral platform,
at Monday evening, two others
were born at the end of the evening Wednesday. At the same time, a
third arm of lavaflow
was thrown into the ocean on the Saint-Philippe side.
3 new cones have shown up on the new coastline
At 01.00 yesterday night, one could see a first cone at a height of
approximately three meters,
located fifty meters in the north of that of Monday evening. Then
a second appeared.
Less than twenty-four hours later, yesterday at 19:15 the eruption
was completed after this last theatric blow.

new cone by the sea, Piton, Tuesday August 31st, 2004
Piton surprises again! On the platform which are now about 500m x
200m broad and from
3 to 6 m thick, there has now been established a new cone - right
out where the ocean waves
came rolling in just one week ago.
Such an eruption 8 or 9 km from the top of the volcano, is completely
There is no precedent since the island where occupied by man.
If this is true, which it looks like it is...one now have the presence
of two distinct events.
One eruption on the top of the island, and one out on the new shore.
However, without the bench
built since August 25th, it is probale that the new eruption would
have occurred under the sea.
On the other side, there is a slight possibility that the cone rocks
in the ocean following a tidal
wave But then the eruptive episodes are particularly violent ones.
Whereas the cone seems
dormant, wrapped in a vapor, it awakes brutally. Strong explosions
are heard and sheaves
of lava rise high in the air. The fireworks lasts half an hour.
The spectacle moves on at the same time in the forest where the lava
cut through a new path
towards the sea in the vegetation.
The episodes follow one another in a random way lasting sometimes
only a few minutes,
intersected with long pauses. The immediate proximity of the ocean
gives an unusual dimension
to the phenomenon. Now, what does the volcano still hold for us? One
point is acquired with
certainty. It will not disappoint us.
If the eruption continues as for now, there is no immideatley danger
for the people on the island,
except for those curious persons who can not get close enough to the

The lava-flow is only visible a few places, as most of the flow go

Piton had a new eruption on August 13th. Since then lava has come
down the hillside,
and met the ocean on the 23rd of August. It is not a violent eruption,
and people are
coming through the woods or by road to watch. The main road is, of

The eruption that began on 2 May is still continuing. Lava flow go
down from the floor
of Enclos by a long tunnel (about 2,5 km) and is issuing at the surface
near the Nez du
Tremblet; Yesterday at 3 PM, lava front flowing at 1150 m elevation,
at about 4 km of the
National Road 2. Volcanic tremor was slight increasing, but remained
at a moderate level.

Cracks opened up a week ago, and a sulphurous odor is hanging
over the mountainside.
Not a big eurption, but lava is coming up in the daylight,

last week, and
it has been difficult to get good pictures through the web-cam on
our web-cam page.
hikers who went yesterday evening to the piton of Bert to observe
the spectacle of the
eruption were disappointed, because in addition to the fall of the
activity noted since the morning,
the fog and the flour were part. Fortunately, there remain these photographs
yesterday morning during an overflight of the enclosure.

Piton of the Furnace could show up to 3 500 seismic tremors for Saturday
only, (approximately 170 to 190 events per hour). The seismicity thus
continues its climbing towards a collapse at the top of Dolomieu.
Friday, December 20th, 2002
As of the 20th of December, the Observatoire Volcanologique du Piton
de la Fournaise has reported that since the stop of the effusive activity,
December 3, a very strong seismic activity is recorded (more than
1000 seismic events per day during last days) strongly suggesting
a pressurization of the system. The seismic events are near the surface
and are at a few hundred meters under the Dolomieu crater. The formation
of a crater of collapse becomes increasingly probable. A very strong
phreatic activity can be associated there and the projection of blocks
to several km of the summit zone is not with exclure.
L' Enclos is always closed and the overflights are prohibited. The
closed area of access must be extended today to all the sector of
Wednesday, December 4th, 2002
lava has now reached the sea at two points.
Someone thought the eruption was over on the island of Reunion recently,
but they were wrong. Pitons has still more to say. But extreme weather
conditions have prevented normal observations
of what's going on. As a matter of fact, 430 mm of rain fell on the
top of the volcano between 04:00 and 23:00 yesterday! Compared to
the 700 mm of annual precipitation in Paris, France,
that gives an idea of the flood which fell down on the solid mass
of the Piton de la Fournaise.
No tremors is thus recorded since yesterday in the
zone of du piton Guanyin, born from the eruption which began on November
16th on the eastern side of the volcano. The seismicity
(1500 events for the day of Sunday) even clearly decreased: whereas
it was not even possible
any more tocount the seisms Monday.Nevertheless, the seismic events
remained on a level
much higher than the normal yesterday evening.
The possibility of a collapse which would affect the top of the volcano
(Dolomieu crater) thus remains as a possibility. For this reason,
the prohibition of overflight of the top in a radius of two kilometers
is more than ever into force and the access to the enclosure remains
On the whole, the main road 2, if one excludes a small enclave of
ten meters, was buried
on nearly 470 meters length. It will have to last several weeks for
the machines to make a provisional track.

on its way down the flanks
The eruption, which began Saturday morning, and sent a flow of lava
down 1 600 m ,
has arrived at 1,4 km from the national hightway, after having increased
its length by 300 meters
in one day. The trémor of the eruption slightly increased between
Sunday and Monday.
The big question is now when the flow will reach the highway, but
at present there is nothing
more to say, except that the duration of the eruption, formation of
tunnels by the lava and a
lot of other unpredictable things all will be parts of the answer
to the question.

to the gendarmerie,

smoke, this point was checked quickly. Following the overflight with
the helicopter of the army: continuous projections
of the cone and 1600 m downwards are visible. The flow on the level
of the cone is unchanged compared to yesterday morning. The lavaflow
increased by approximately 300 m since
yesterday morning and are to 1.4 km from the trunk road. No release
of smoke was
observed in the Plain of Osmunds. The Picard crater is absolutely

Siden den 11 januar har den seismiske aktiviteten
tiltatt til det dobbelte av foregående
uke, med jordskjelv omkring 4 km under Plaine des Osmondes,
nær den nordre
kaldera-veggen. Om kvelden den 12.januar åpnet det seg en ny
sprekk i den lavere delen
av Plaine des Osmondes. Lava fløt ut herfra ned mot Grand Brulè.
Den 14 januar
fløt lavastrømmen over riksveien på sin vei mot
havet, hvor det nådde fram sent
på ettermiddagen. 15. januar var skjelvene stabile, med omkring
100 skjelv registert
over en 24 timers periode på nordsiden av vulkanen. Kl. 06.00

gir seg ikke med det første denne gangen heller
Ingen aktivitet var synlig i går, og man vurderte
å åpne veiene for tilskuere, det er tross
alt derfor mange turister kommer til Reunion, og etter 24 timers stillhet
trodde man at
det var over for denne gang. Den seismiske aktivitet har imidlertid
tatt seg opp igjen,
og man frykter nå at flere åpninger vil dukke opp.
Man sammenligner nå hendelsesforløpet med utbruddet i
1977, hvor man også hadde en
6 timers utbruddsperiode, hvoretter alt ble stille - for så
plutselig å konstatere at
nye åpninger dukker opp, og nye lavaflommer lyser opp fjellskråningene

Årets første større utbrudd foregikk på
øya Reunion nær Madagaskar, og begynte den
5.januar kl. 23.00 lokal tid. Utbruddet var til å begynne med
ganske voldsomt, og sendte
kaskader av lava nedover fjellsiden mot Osmunds-lavsletten. 12 timer
senere, søndag formiddag, var bare 2 av de 4 åpningene
aktive. Søndag kveld skal den seismiske aktiviteten ha avtatt,
og bare en av de fire åpningene fremdeles aktive.
