Hoʻomaha: to rest.

Episode kanahā kūmāiwa (49) ended at 5:05 p.m. HST after 7.5 hours of fountaining. The north vent fountain dropped rapidly from 200-300 hundred feet (60-90 m) just after 5 p.m. and then began jetting tephra in bursts for the last 2-3 minutes, according to USGS Hawaiian Volcano Observatory.

🌋Kīlauea is erupting. Episode kanahā kūmāiwa (49) began at 9:36 a.m. HST, according to USGS Hawaiian Volcano Observatory. The north vent fountain is now about 300 feet high and growing. The gas plume is about 12,000 feet above sea leavel and moving to the southwest.

Park managers are not expecting temporary closures at this time, but that could change based on wind direction, volcanic gas and tephra fallout.

✔️Planning to visit? Stay safe and follow this check list:

🚧 Stay out of closed areas. Serious injuries have occurred in closed areas, and entering puts you and park staff at risk. Excellent, safe viewing opportunities are available in open areas.

🧠Stay away from cliff edges, they are unstable and undercut. If you feel the ground shaking, move further away from the caldera edge.

💯Monitor air quality: https://www.nps.gov/havo/air-quality-alert.htm. If unhealthy levels of volcanic gas (vog) are present or tephra starts falling, leave the area.

🚫Temporary closures may occur if vog or tephra (falling volcanic material) create hazardous conditions.

🥽Protect yourself from tephra: shelter indoors or in your vehicle; use eye protection, hat, long sleeves/pants, gloves. Dust masks help protect your respiratory system from tephra (not vog).

🚗Expect heavy traffic near the entrance and along Hwy 11.

🛑Slow down, follow signs, watch for detours, and listen to rangers.

🚙Park only in designated areas; don’t block roads or emergency access.

🔒Do NOT leave valuables in your car — most break-ins happen when items are left visible.

🚶🏽‍➡️Pedestrians: stay alert and use sidewalks/crosswalks.

👀Watch for nēnē on roads and in parking lots; never feed wildlife.

Precursory activity has begun within Halemaʻumaʻu crater. USGS Hawaiian Volcano Observatory has raised the alert level for Kīlauea volcano to orange, and the onset of episode 49 fountains is most likely today, Sunday, June 14 or tomorrow.

According to USGS HVO, a second precursory overflow began at 5:59 a.m. HST fed by a 15-foot dome fountain from the north vent. Early risers viewing in person or on the USGS HVO livestream cameras were treated to spectacular colors at daybreak.

Plan to visit? Today is a fee-free day in observance of Flag Day and the park will be busy. See our pinned post for a checklist of how to prepare for your visit and stay safe. LIght winds are out of the north, keep your eye on air quality here: https://www.nps.gov/havo/air-quality-alert.htm
