Seen from Space 2004
Mt. Asama seen from space
MODIS sensors aboard NASA's Earth observation satellites Terra and Aqua captured the ash plume and water vapor from Mt. Asama. Mt. Asama is located at 36°24'12"N, 138°31'34"E and appears in the upper left of the images. Figure 1, observed at 10:28 a.m. on September 16, 2004, shows the ash plume from Mt. Asama stretching southward over Kofu city. In Fig. 2, observed one and a half hours later, the ash plume widens a little, continues stretching southward, and eventually extends over Suruga Bay.
Color composition was made by using MODIS 250 m resolution channels 1 and 2, and assigning channel 2 (841 - 876 nm) to red, channel 1 (620 - 670 nm) to green and blue, resulting in the figures below.
Figure 2 looks a bit blurred compared to Fig. 1 because Fig. 2 was captured near the edge of the MODIS sensor field of view. Related sites:  MODIS near-real-time images
