The details

The eruption began on Tuesday morning when seismic activity and tilt measurements at the volcano increased. Two vents, one north and one south, are producing voluminous tephra (volcanic rock fragments) that is spreading to the north. Ashfall up to 5 inches in size has been reported in communities like Mountain View and Glenwood, prompting the Ashfall Warning. The summit of Kīlauea is closed, and a portion of Highway 11 has also been shut down.
