North vent fountains are now reaching 650 feet (200 meters) high with tephra being carried to the southwest at lower elevations. The top of the plume cloud has reached 20,000 feet a.s.l. and is moving to the northeast above 15,000 feet.

North fountains are now about 500 feet (150 meters) and leaning toward the north. Small south vent fountains (under 50 feet or 15 meters) began around 4:30 pm HST.

North vent fountains have grown to over 300 feet high (100 meters) and are broad. Approximate effusion rate is 120-240 cubic yards per second. The top of the convective plume cloud is at 13,000 feet and is visible from Mauna Loa.

North vent fountains are beginning to grow rapidly have reached about 200 feet (60 meters) at 4 pm HST. Tremor is also increasing rapidly and tilt dropping indicating peak fountains should occur in the next 30-60 minutes.

North vent fountains have been continuous since 3 pm HST and have grown to about 65 feet (20 meters) high. Periodic overflows continue from the south vent. Tremor and tilt show episode 47 underway as of 3:27 pm.

Vigorous dome fountains began from the north vent at 3 pm HST. This appears to be a prelude to the start of episode 47 but tremor remains low at this time.

The Halemaʻumaʻu north vent is reawakening after slowly dribbling lava most of the day. V1cam appears to show lava effusing from the western of two closely spaced vent openings, then it descending into the eastern opening.

The have been over 40 precursory overflows from the south vent this morning since 3 a.m. HST. Tremor and tilt both remain constant, typical of precursory activity. A small stream of lava can be seen on the backwall of the north vent.

There have been more than 10 overflows from the south vent so far and they are increasing in frequency but decreasing in duration. Tilt is currently flat around the summit and tremor remains constant.

An overflow from the south vent began at 2:57 a.m. HST this morning, the first in advance of an expected lava fountaining episode 47 at Kīlauea summit. Further dome fountains and overflows are likely to precede the onset of fountaining.
Kilauea Message 2026-05-13 17:42:23 HST
As darkness falls over Halemaʻumaʻu this evening, V1cam is providing views of periodic north vent spattering. This indicates that lava is close to the surface, and that fountaining episode 47 may be nearing.

HVO has lowered the Volcano Alert Level for Kīlauea from WATCH to ADVISORY, and the Aviation Color Code from ORANGE to YELLOW, following the end of episode 46 lava fountaining.
