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.
