Region: | Africa and Red Sea |

Geodetic measurements? | Yes |
Deformation observation? | Yes |
Measurement method(s): | InSAR |
Duration of observation: | 2008 - 2010 |
Inferred cause(s) of deformation: | Magmatic |
Characteristics of deformation: | In November 2008 an eruption occurred at the Alu-Dalafilla volcanoes, causing lava flows to extend to the NE. Pagli et al. (2012) showed that this eruption was sourced by a 1 km deep elongated magma chamber that exists in two segments, and was probably trigged by an influx of magma from the north. Both magma chamber segments appeared to source the eruption though a connecting dyke. The magma chambers have since, rapidly, refilled. |
