Active volcanoes / Aktive vulkaner:
Tengger, Indonesia   

The Tengger massive volcanic area stretches all the way up
to the Semeru volcano, which lies in the background. In the lower left corner
steam is coming up from Bromo, and in the lower center part - the old Batok-volcano.

The symmetrical stratovolcano rises abruptly to 3,676 m above coastal plains to the S and
lies at the southern end of a volcanic massif extending N to the Tengger caldera. Semeru has
been in almost continuous eruption since 1967. Frequent small-to-moderate Vulcanian eruptions
have accompanied intermittent lava dome extrusion, and periodic pyroclastic flows and lahars
have damaged villages below the volcano. A major secondary lahar on 14 May 1981 caused
more than 250 deaths and damaged 16 villages.

Tengger-kalderaen lies on the easternmost part of Java

According to the Darwin VAAC, CVGHM stated that an eruption from Tengger Caldera's Bromo cone had occurred
on 26 November. An ash plume detected in satellite imagery rose to an altitude of 13.7 km (45,000 ft) a.s.l. and
dissipated. During 27-29 November satellite imagery showed ash plumes drifting 55-165 km at an altitude of
4.3 km (14,000 ft) a.s.l.

The status of Bromo volcano was raised to the highest red alert level at 3:30 pm (0830 GMT) on Tuesday.
Bromo started rumbling on November 8 and plumes of white smoke and ash were rising from the crater of the
2,329 metre (7,640-foot) peak on Tuesday
Dangerzone at present is 3 km from the crater. The countryside around Bromo is not densely populated as it lies
within the Bromo-Tengger-Semeru National Park.

At least two hikers, including a Singaporean, were killed five others injured as Mount Bromo, a popular tourist
destination (see below) , unexpectedly spewed black smoke and hot ash on Tuesday.

June 29th, 2004
Mt Bromo erupted on Tuesday, June 8th, killing two people and injuring five others.
The volcano ejected hot rocks the size of footballs from the crater at 3:30pm local time.
Search and rescue teams have been advised to stay away from the volcano until it is
declared safe to approach, and Bromo has been closed to the public until further notice.

Bromo erupted (phreatic eruption), sending ash up to 3000 meters above the crater's edge.
The duration was about 20 minutes. Rocks and ash spread in a radius about 300 meters
from the centre of crater. The ash blown by wind to the west west north and was detected
at G.Kelud observatory. Many buildings in the nearby towns of Malang and Probolinggo
were covered by a light coating of ash two hours after the eruption. The neighbouring towns
of Lumajang and Pasuruan were also affected by the eruption. Mt Bromo is a popular
tourist destination, and many visitors climb to the crater's edge.

In June Mount Bromo shot out a shower of rocks and stones which killed a 13-year-old
Singaporean boy and an Indonesian.

The volcano has erupted more than 60 times since 1767.

esember 21st, 2000
Explotions and tremors has increased last 7 days compared to the week before.
Minor explotions sent up grey-brown dark ashcolumns which reached apprx 500 m heigth.
Seismographic monitors registered a fantastick number of quakes, a total of 2.375 during
one week.

Steam rising from the Bromo-volcano to the left, while Batok - another of the youngest
volcanoes in the Trengger-massive is shown in foreground. The picture has been taken from the
edge of the Ngadisari-caldera, the oldest of the two calderas in Terngger. In the background Semeru volcano is clearly shown.

On of the most popular volcanoes in
Indonesia. You walk by foot or ride across
the flat Sandsea and climb up the stairs on
the slope of the Bromo-volcano.
When it explodes, you rush down

View of the flat Sandsea-bottom, and in the background the edge
that borders the 16 km wide Ngadisari-caldera.
