Despite the somewhat reduced intensity of tephra fall around Kīlauea Military Camp, conditions remain hazardous: a HVO field crew in the area just reported that tephra clasts up to softball-sized are still dropping.
Kilauea Message 2026-04-09 14:00:18 HST
Within the past 15 minutes, field reports have indicated a reduced intensity of tephra fall around Kīlauea Military Camp. This is consistent with very slightly declining lava fountain heights at the Halemaʻumaʻu north vent.

Outside Hawaiʻi Volcanoes National Park across Highway 11, tephra up to 30 centimeters (12 inches) in size has been reported to have fallen in the Volcano Golf Course subdivision.

Lava fountains have reached a peak estimated height of around 800 feet. Based on elapsed time, tremor values, and effusion rate, this may be as high as episode 44 lava fountains will reach.
Hawaiian Volcano Observatory Message 2026-04-09 13:43:00 HST
Peak lava effusion occurred around 12:30p with an esimtated rate of 500+ cubic yards per second from a single vent (north). By comparison, episode 43 peaked near 1,200 cubic yards per second from two vents (north and...
Kilauea Message 2026-04-09 13:26:01 HST
North vent lava fountains have reached 240 meters (800 feet) in height during the past hour. Seismic tremor appears to have reached a plateau, indicating that the fountains may have already reached their maximum for episode 44.
