MODIS true color image of Russia on the 12th of January 2004 above.
Klyuchevskaya Sopka, the largest volcano on the Russian peninsula of Kamchatka, and Shiveluch, a neighboring volcano, are becoming active again. According to news reports, Klyuchevskaya is sending ash to a height of 50 meters. The 15,863-foot tall volcano is the region's most active; its most recent eruption ended in January of 2003.
The false-color image shows the plumes more clearly. Snow and ice appear red/orange, while the smoke plumes are slightly pink and ash is light blue. These images were acquired by the Terra MODIS instrument on January 12, 2004.
Shiveluch, the volcano at upper center with the darkest ash plume, erupted on January 11, 2004, sending volcanic ash to a height of 1.5 kilometers while rock and melted snow rained down the mountainside. At a height of 10,771 feet, Shiveluch is one of the region's largest and most active volcanoes. Its last eruption, which lasted for two years, ended late last year. Neither volcano is endangering local towns.
The ash plumes from both volcanoes are faintly visible in the true-color image (top). Brown ash dusts the snow around Shiveluch. Below Shiveluch and to the left, Klyuchevskaya has a thin, barely-visible plume of ash flowing east from its top.
