🌋Kīlauea eruption episode 48 summary - a historic new record for Kīlauea!   

Episode 48 of the Kīlauea summit eruption in Hawai‘i Volcanoes National Park stopped at 1:37 pm HST June 1 after 9 hours of lava fountaining. This eruption has now surpassed the number of fountaining episodes in the opening years of the Puʻuʻōʻō eruption from 1983-1986 (47), setting a new record number of fountaining episodes in any one Kīlauea eruption.    

🌋 Lava flowed from the south vent about 95 times in the days before episode 48, but only the north vent produced a lava fountain (up to 650 ft/200 m) during the episode. This pattern has been followed during the past several episodes. An estimated 7.3 million cubic yards (5.6 million cubic meters) of lava spilled across Halemaʻumaʻu.    

💨 The eruptive plume rose to about 24,000 ft (7,300 m) above sea level; higher level winds from the south caused tephra to fall north and east of Kaluapele (Kīlauea caldera) at overlooks within Hawaiʻi Volcanoes National Park, as well as on Highway 11 near Nāmakanipaio Campground, Volcano village, Mauna Loa Estates, and Ohia Estates. The National Weather Service issued an ashfall advisory for these areas downwind.    

⛔️ The USGS kept the Kīlauea alert level/aviation color code at WATCH/ORANGE throughout the episode because fallout was not extensive and did not last very long. After the episode ended, USGS lowered Kīlauea to ADVISORY/YELLOW reflecting that volcanic activity had decreased significantly but continues to be closely monitored for possible renewed increase.    

Kīlauea summit region inflation since the end of episode 48 indicates that another fountaining episode is possible; however, more time is needed to collect data to generate the model to forecast episode 49, which will set a another new record for Kīlauea.

Out in remote country, RAWS work quietly 24/7, tracking wind, temperature, humidity, and other key weather data that help firefighters and fire managers operate safely and effectively.

RAWS, or Remote Automatic Weather Stations, continuously collect on-the-ground observations that support fire weather forecasting, operational planning, and critical decision-making in the field. There are more than 2,400 permanent stations across the United States, Guam, Puerto Rico, and the U.S. Virgin Islands, along with 75 portable units that can be deployed during wildfires, prescribed burns, or post-fire projects.

Behind every reliable data point is a dedicated team of technicians working year-round to keep these stations accurate, maintained, and functioning. Sometimes that means flying by helicopter to a remote mountaintop to install an Incident Remote Automatic Weather Station (IRAWS), ensuring firefighters have access to critical weather data in the field.

Kilauea Message 2026-06-01 05:07:50 HST. North vent fountains increasing in height to about 200 feet (60 m). Tremor also continues to increase as episode 48 ramps up. Expecting 600-800 foot (180-250 m) high fountains within the hour.

[Hawaiian Volcano Education & Resilience Institute @HVERI_org]

Episode 48 began at 4:40 a.m. HST on June 1. The north vent began overflowing at 3:45 a.m. HST, fed by sustained dome fountaining about 15–30 feet high. By 4:11 a.m.

How can we keep bears and park visitors safe together? Proper food storage and trash disposal!

The most effective action for bear and human safety is to store food and scented items properly. Storage boxes are available in picnic areas, campgrounds, and some trailheads. If there isn't a storage box nearby, ensure food and scented items are hidden and locked inside your vehicle - do not leave food in open truck beds.

Black bears are curious and will attempt to get human food. The more food they are able to obtain, the bolder they behave, which is why proper trash disposal is also very important. When disposing trash, ensure the bear resistant lid is completely closed. If the bin is full, please do not leave trash piled up around the area.

Give bears space and if you see a bear obtain food or trash, please report it at a visitor center.

Four fountains. One unforgettable week. As America counts down to her 250th Anniversary, history isn’t just remembered — it’s flowing again.

This week’s ribbon cuttings at the Taras Shevchenko Memorial, General Philip Sheridan Circle, Dupont Circle and Meridian Hill Park marked a triumphant return, with fountains and statues sparkling and waters flowing once again, each one a celebration of history, community, and beauty restored.

This is President Trump’s vision in action. Through the Making DC Safe & Beautiful, we are restoring the heart of our nation’s capital and putting America on the path to having the most beautiful capital city in the world.

We couldn’t be more grateful. Thanks to the National Park Service experts for their care of our national spaces.

And here’s to the water flowing again.

USGS–Hawaiian Volcano Observatory scientists conducted a monitoring overflight of Kīlauea summit on May 22, 2026, and observed/measured the following: 
 
➖Magma pooled and glowing within both north & south vents
➖Sulfur dioxide emissions averaged around 2,000 tonnes/day (typical during pauses between episodes)
➖Plume drifting southwest into the Kaʻū Desert
➖Collected thermal and visual imagery of the tephra cone on the crater rim, the crater‐walls, and new lava flows on the crater floor
➖With permission from Hawaiʻi Volcanoes National Park, collected a sample of episode 47 lava flows
 
🔭 Episode 48 lava fountaining is projected between May 24–27.
