Kīlauea Volcano — Fissure 8 Cone Changes (GIF)

This animated gif shows the fissure 8 tephra (cinder and spatter) cone morphology changes between June 15 and 24, 2018. During this time a shoulder grew on the channel side of the cone as the vent shifted from being two distinct fountains to three, then to a single source of voluminous roiling. The cone height is about 47 m (154 ft) from the hardened lava surface on which it was built.
