The eruption, which carried a risk of lava flows and deadly volcanic gas, caused the evacuation of 30,000 residents.

The crater was clearly changed by the April 2005 eruption.
A grey field of ash surrounds the crater and the caldera itself seems larger and deeper.
The crater lake, which formed after Karthala's last eruption in 1991 and once dominated the caldera, is now gone completely.
In its place were rough, dark grey rocks, possibly cooling lava or rubble from the collapsed crater.
