Hertali

割れ目火口 · Ethiopia · 900m

The dark-colored area cutting across the center of this NASA Landsat image (with north to the top) is a series of basaltic lava flows erupted from fissure vents at Hertali. These flows lie at the S end of the Awash Plain, about 50 km NNE of Dofen volcano. The youthful morphology of the flows suggests a late Pleistocene to Holocene age. Numerous NNE-SSW-trending fissures of the Ethiopian Rift are visible. · 写真: NASA Landsat 7 image (worldwind.arc.nasa.gov) · Wikimedia Commons

地質学的概要

Hertali is a basaltic fissure vent that fed lava flows at the S end of the Awash plain, about 50 km NNE of Dofen volcano. It was considered by Mohr and Wood (1976) to have been active during the late Pleistocene to Holocene on the basis of its youthful-looking morphology.
