East African Rift (ASTER), Places where the earth's crust has formed deep fissures and the plates have begun to move apart develop rift structures in which elongate blocks have subsided relative to the blocks on either side., Places where the earth's crust has formed deep fissures and the plates have begun to move apart develop rift structures in which elongate blocks have subsided relative to the blocks on either side. The East African Rift is a world-famous example of such rifting. It is characterized by 1) topographic deep valleys in the rift zone, 2) sheer escarpments along the faulted walls of the rift zone, 3) a chain of lakes within the rift, most of the lakes highly saline due to evaporation in the hot temperatures characteristic of climates near the equator, 4) voluminous amounts of volcanic rocks that have flowed from faults along the sides of the rift, and 5) volcanic cones where magma flow was most intense. This example in Kenya displays most of these features near Lake Begoria. The image was acquired December 18, 2002, covers an area of 40.5 x 32 km, and is located at 0.1 degrees north latitude, 36.1 degrees east longitude.

東アフリカのリフト(ASTER) 地殻が深い裂け目を形成し、プレートが離れ始めて移動する場所。両側面のブロックに対して細長いブロックが沈降する裂け目構造が発達する。地殻が深い裂け目を形成し、プレートが離れ始めた場所。両側のブロックに対して細長いブロックが沈降する裂け目構造が発達する。東アフリカのリフトは、そのようなリフトの世界的に有名な例である。地溝帯の地形深谷、断層壁に沿った断層、地溝内の湖のチェーン、赤道付近の気候の特徴である高温での蒸発による塩分濃度の高い湖、地溝断層の断層から流れ出した火山岩の多量、マグマ流が最も強かった火山円錐が特徴である。ケニアでは、これらの機能のほとんどはベゴリア湖の近くにある。画像は2002年12月18日に取得され、北緯0.1度、東経36.1度、面積は40.5×32km。
