摘要

描述
English: Turrialba Volcano, located in central Costa Rica, emits a translucent plume of volcanic gases in this natural-colour satellite image. The barren summit region of the 3,340-meter high Turrialba appears grey and brown, while the volcanic plume is a hazy blue. Fields and pastures are light green, in contrast to dark green forest that covers the high-elevation ridges. Since 2007, frequent acid rain showers caused by activity at the volcano killed or damaged much of the vegetation to the south-west of the summit, leaving the area brown and orange.
