South of this volcano is the Gumatmali-Gablaytu fissure system, an area dominated by fissure-fed lava flows.

Manda Hararo's large size is because it is a raised block from the end of a mid-ocean ridge spreading center.

NASA's Aura Satellite detected a large sulfur dioxide plume over Ethiopia and Sudan.

After the main eruption, lava flows continued and much of the fissure gave off strong fumarolic activity.

A team of field scientists reached the site on 4 July and found the eruption had produced basaltic lava flows from fissures 4–5 kilometres (2.5–3.1 mi) long.
