Alid

Volcano number:221040
Region:Africa and Red Sea
Country:Eritrea
Geodetic measurements?Yes
Deformation observation?No
Measurement method(s):InSAR
Duration of observation:2005 - 2010
Inferred cause of deformation:
Characteristics of deformation:

Alid is a elongated (east-west) stratovolcano located in the Danakil depressed, Afar. Deposits are mostly basaltic to rhyolitic lava flows. Pagli, et al. (2014), for the purposes of investigating regional velocity fields, has looked at Envisat InSAR data (2005 – 2010) covering this volcano. They report no deformation. Some fumarolic activity can be found towards this north of this volcano however.

The most recent eruptions are thought to be fissure eruptions of Holocene age (Siebert and Simkin, 2002). .
