Picture post: Sarychev before and after - July 01, 2009
New images of the Great Beyond’s volcano of the year (to date): Sarychev Peak in the Russian Kuril Islands.
Although not quite on a par with the awesome shot from last week (see: Picture post: BOOM!) this double act show the impact of an eruption like the one that Sarychev experienced beginning 12 June. The ‘before’, top, was taken 26 May while the ‘after’, below, is from 30 June.
Acquired by the ASTER instrument that graced this blog yesterday, these false-colour images show vegetation as red, water as dark blue, and bare rock as brown / gray. The white patches are either ice or clouds.
The most striking difference between these two images is the cap of new volcanic rock coating the northwestern half of the island in June 2009. While vegetation on the rest of the island appears lush, little or no vegetation remains on the northwestern end. A close look at the top image also reveals that the recent volcanic activity appears to have expanded the island’s coastline on the northwestern end.
