Tat Ali

Volcán en escudo · Ethiopia · 655 m

The Tat Ali volcanic massif extends across the right-hand side of this NASA Landsat image, east of Lake Afrera (center). This basaltic-to-pantelleritic shield volcano displays an elongated central depression partially filled by recent basaltic lava flows. The dark-colored flows at the upper right were erupted from fissures at the northern end of the Tat Ali complex. Borawli volcano lies at the right-center, between Tat Ali and Lake Afrera (also known as Lake Giulietti), and the lava flows at the upper left are from the flanks of the Hayli Dubbi complex.

Resumen geológico

Tat Ali volcano is the dominant feature of the Tat Ali Range, east of Lake Afrera. The low Holocene shield volcano has an elongated summit depression and has produced a variety of rock types, ranging from basalts to pantellerites. NNW-SSE-trending fissures cutting the volcano have fed basaltic lava flows; those NE of Lake Afrera are of prehistorical age. Late-stage volcanism produced youthful basaltic lava flows on the floor of the summit depression, which is also the site of prominent fumarolic activity.

Resumen de Wikipedia

Resumen en inglés

Tat Ali is a low Holocene shield volcano located in the northern part of the Afar Region of Ethiopia. This elevation is characterized as having an elongated summit depression that has produced a variety of rock types, ranging from basalts to pantellerites. NNW-SSE-trending fissures cutting the volcano have fed basaltic lava flows; those NE of Lake Afrera are of prehistoric date. Late-stage volcanism produced youthful basaltic lava flows on the floor of the summit depression, which is also the site of prominent fumarolic activity.
