Bromo volcano (East Java, Indonesia): eruption warning due to increased seismic and degassing activity

Tremor intensity at Bromo (PVMBG)
An eruption warning was issued this morning - PVMBG raised the volcano's alert status to "siaga" (alert), or 3 on a scale of 1-4.
Seismic activity and degassing from the crater have sharply increased, suggesting that a new eruption could occur any time at the volcano.

Sunday, Nov 15, 2015
A phase of increased unrest seems to have started at the volcano. On 1 November, the local volcano observatory issued a warning not to approach Bromo within 1 km radius, as changes in seismic activity and increased steaming/degassing (including sulfur dioxide) had been noted. ... [mehr]
Wednesday, Oct 03, 2012
A sharp increase in volcanic tremor recorded this morning at Bromo volcano prompted the Indonesian Volcanological Survey to raise the alert level for the volcano from 1 (normal) to 2 (unrest) on a scale of 1-4. ... [mehr]
Thursday, Apr 05, 2012
During the past weeks, only white plumes were seen at Bromo rosing to about 50 m above the crater and seismicity declined. On 30 March the Alert Level was lowered back to 1. [mehr]

Thursday, Jan 01, 1970
As observed on location today, Bromo erupts dense clouds of ash, rising to about 1 km above the crater, drifting east. The emissions fluctuate in intensity with phases of weaker and strong emissions alternating ca. every 20 minutes. The activity is often accompanied by near continuous roaring noises resembling a strong surf. During stronger phases, loud explosions sounds heard in many kilometers distance as well as shock waves rattling windows in nearby villages accompany the eruptions. [mehr]

The VAAC Darwin reports an ash plume from Bromo's eruption rising to 26,000 ft (ca 9 km) drifting 90 nm NW reaching Surabaya. A low-level plume at 10,000 ft (ca. 3 km) is drifting 20 nm SE. [mehr]

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.
