Bromo volcano (East Java, Indonesia): intermittent ash-rich explosions, ash venting

Monday Feb 08, 2016 12:21 PM | DOOR: T

Ash-rich strombolian eruption at Bromo yesterday

The eruption continues in the form of intermittent small to moderate strombolian-type explosions and minutes-long phases of more or less vigorous ash venting alternating with strong degassing. Only few incandescent ejecta are being seen at night, but ash emissions are comparably intense and aviation color code of the volcano remains at orange.
Our friend Øystein Lund Andersen visited the volcano yesterday and reported:
"Heavy degassing was observed during arrival in the afternoon, accompanied by a irregular but periodically heavy rumbling sound. ... After these periods of calm, larger degassing plumes tend to appear, accompanied by large rumbling sounds and in one case an eruption at 14:14. The eruption was accompanied by a shock wave, and seconds after an ash plume appeared that reached around 800m in height. Sounds of falling rocks or blocks was heard seconds after the appearance of the eruption plume. The ash content decreased within 30min after the eruption.
...
Next eruption happened at 15:45, and the ash-plume was sustained for around 45minutes. ...The next eruption started at 16:50. ... Late evening, intense crater-glow was seen minutes before a small eruption (23:41)...

Background:

Gunung Bromo (Mount Bromo) volcano is a small, but active volcanic cinder cone on the Indonesian island of Java. Bromo is located in the center of the Sandsea Caldera, itself only a portion of the larger Tengger Caldera. The Sandsea caldera formed around 8,000 years ago, in what must have been a massive eruption. Subsequent volcanic activity formed the cluster of cinder cones in the caldera’s center, including Bromo.
The historical record indicates eruptions of Bromo every few years since 1804, and geologic evidence indicates eruptions at least several hundred years earlier. The most recent eruption occured in 2004, and tragically killed two tourists.


The image above shows most of the Sandsea Caldera, along with Gunung Bromo and the older volcanoes on the caldera floor. A small plume of steam is visible rising out of Mt. Bromo. Space Imaging’s IKONOS satellite, capable of 4-meter per-pixel color imagery, and 1-meter per-pixel resolution panchromatic imagery, acquired the data on July 8, 2001.
