Figure 10-20. A SIR-C/X-SAR image (composite of L and C-bands) of the Kliuchevskoi volcano, Kamchatka, Russia (blue triangular peak in the center) which erupted in 1994. Melting snow mixed with volcanic ash triggered mudflows on the flanks of the volcano shown as thin lines in various shades of blue and green on the north flank in the center of the image. Two other active volcanoes are visible in the image.
