Adwa

Estratovolcán · Ethiopia · 1670 m

A caldera 4 x 5 km wide cuts the summit of Adwa volcano above the center of this NASA Landsat image with N to the top. This prominent volcano (also known as Aabida, Amoissa, or Dabita) is in the southern Afar area immediately E of Ayelu volcano, which lies above and to the left of the westernmost flank lava flow. These prominent young basaltic lava flows were erupted from vents on the W, E, and S flanks of Adwa volcano and overlap a sedimentary plain to the SE.

Resumen geológico

Adwa (also known as Aabida, Amoissa, or Dabita), is a broad stratovolcano in the southern Afar area immediately east of the younger vegetated Ayelu volcano. It has a roughly 3 x 4 km caldera that originated following eruption of voluminous ignimbrites, with a trachytic dome extruded in the eastern part of the caldera. Scoria cones are located on the floor of the caldera and on its NW and SW flanks. Extensive young basaltic lava flows cover the flanks and overlap a sedimentary plain to the SE. Many fumaroles occur within the caldera. Satellitic pyroclastic cones and lava domes were considered to be only a few hundred years old (Mohr 1980, pers. comm.). Dark lava flows originating from cones about 4 km from the caldera rim on the SW flank cover more than 50 km2.

Resumen de Wikipedia

Resumen en inglés

Adwa is a stratovolcano in Ethiopia, located in the western Afar Region region and has a 4 by 5 km caldera. Due to the location of the volcano near the boundary between Afar and Issa tribes, little is known about the past and present behavior of the volcano. However, an earthquake and InSAR study conducted by Derek Keir and colleagues shows that a magma intrusion around 5 km deep and 8 km long emanated away from the eastern side of the volcano in May 2000.
