Despite being one of the most active volcanoes in Papua New Guinea, Bagana is poorly monitored. Located on the mountainous spine of Bouganville Island, it is both far from any cities or large towns and hard to reach due to the rough terrain. Bagana emits volcanic gases (including water vapor and sulfur dioxide) almost continuously, and frequently extrudes thick lava flows. Satellites provide the most reliable way to watch this activity.

This composite image compares observations after the earthquake to images of lights observed in 2010. Yellow indicates lights that were functioning in both 2010 and 2011, and includes Tokyo and areas to the south and west. Red indicates power outages detected on March 12, 2011, compared to data from 2010. Areas of power loss include Sendai, and coastal locations north of Tokyo. Blue indicates clouds, and that blue also tints some of the yellow-lit areas to green. Magenta (visible south and west in the large image) indicates lights obscured by clouds. Bright green spots

The images combine infrared, red, and green wavelengths of light to form a false-color image that distinguishes between muddy water and land. Water is blue. Buildings and paved surfaces appear in shades of blue-gray. Fallow fields appear in shades of beige and brown. Vegetation is red, and the brighter the red, the more robust the vegetation. (Brighter shades of red in March and duller shades in January result largely from the difference in season.)
