An ash plume rose from the Overlook crater at Kīlauea's summit.

At 9:06 a.m. HST, 5/11/18, an ash plume rose from the Overlook crater at Kīlauea's summit. Similar to recent plumes, this event was likely caused by a rockfall from the crater's steep walls. The plume's reddish color is most likely from altered rock and ash fragments that fell into the deepening conduit.
