The only recorded eruption of Dalaffilla occurred in 2008 when lava flows from its western and northwestern flanks traveled to the northeast.

It has a shallow gradient in its lower section, but the upper portion of the volcano is extremely steep.

[2] The Global Volcanism Program describes the volcano's location as "a hot, arid, and desolate rift basin" that lies up to 100 meters below sea level.

[4] Initial reports of the 2008 eruption claimed a level of lava output that turned out to be 20 times too large.

The location of the eruption was also erroneously thought to be further east than it really was, due to older and imprecise maps.
