Question 1

What is the active volcano in Hawaii right now?

Accepted Answer

Kīlauea volcano on the Big Island of Hawaiʻi is one of the world's most active volcanoes, located inside Hawaiʻi Volcanoes National Park (HVNP). Mauna Loa — the world's largest shield volcano — also sits within the same park and erupted in November 2022, but has been quiet since. For visitors today, the main focus is Kīlauea and activity within the Halemaʻumaʻu crater at the summit.

Question 2

Is Kīlauea erupting right now?

Accepted Answer

Kīlauea is in an active episodic eruption cycle — short lava fountaining episodes separated by multi-day pauses. Check hawaii-watch.com for the most current status, updated every 5 minutes from USGS HVO data.

Question 3

When will Kīlauea erupt next?

Accepted Answer

Scientists estimate eruption windows by monitoring summit tilt, seismic activity, and GPS ground deformation. Based on recent episode patterns, intervals typically run 5–15 days. See the live forecast module at hawaii-watch.com for the current prediction, updated every 5 minutes from USGS HVO data.

Question 4

What is summit tilt and why does it matter?

Accepted Answer

Electronic tiltmeters measure tiny changes in the slope of the ground near the volcano's summit — like an extremely sensitive carpenter's level. When magma fills the reservoir beneath the summit, the ground inflates (tilts upward). When it erupts, the ground deflates as magma exits. This inflate → erupt → deflate cycle is one of USGS's primary tools for timing the next episode.

Question 5

How do scientists predict volcanic eruptions?

Accepted Answer

USGS uses a combination of monitoring tools: electronic tiltmeters (ground deformation), seismometers (underground magma movement), GPS (inflation/deflation), gas emissions (SO₂ output), and thermal cameras (heat anomalies). By correlating multiple data streams with historical episode patterns, scientists can provide reasonable forecast windows days to weeks ahead — but pinpointing hour-by-hour timing remains challenging.

Question 6

Is it safe to visit Hawaiʻi Volcanoes National Park during an eruption?

Accepted Answer

Always check the Hawaiʻi Volcanoes National Park website (nps.gov/havo) and follow guidance from park rangers and USGS HVO before visiting. Conditions can change rapidly — some trails close during active eruptions, vog (volcanic smog) can affect air quality, and eruption intensity varies. This site is for informational purposes only. Always defer to official NPS, USGS, and Hawaii Emergency Management Agency guidance for safety decisions.

Question 7

What is a volcanic eruption "episode"?

Accepted Answer

An episode is a discrete fountaining event within the summit caldera, typically lasting hours to days. Between episodes, the volcano enters a recharge phase where the magma reservoir refills. Since September 2023, Kīlauea has cycled through dozens of episodes. Each episode is numbered, and USGS tracks metrics like fountain height, lava volume erupted, and duration.

Question 8

How often does Kīlauea erupt?

Accepted Answer

In the current (2023–present) active cycle, episodes occur roughly every 5–15 days. Before this, Kīlauea had a major 2018 eruption that sent lava flows into residential areas, and a continuous eruption from 2008–2018 that lasted a decade. Historically, Kīlauea is one of the most frequently erupting volcanoes on Earth — it has rarely been fully quiet in recent decades.

Question 9

What are volcanic gases (vog) and are they dangerous?

Accepted Answer

Vog (volcanic smog) is formed when SO₂ gas from the eruption reacts with moisture and oxygen in the atmosphere to create a sulfuric acid haze. It can cause respiratory irritation for sensitive groups — asthmatics, elderly, children, and pregnant visitors. Vog levels vary with wind direction. Check the IVHHN Vog Forecast at vog.ivhhn.org before visiting. Bring an N95 mask and step back if you feel symptoms.

Question 10

Where can I view a Kīlauea eruption on the Big Island?

Accepted Answer

The best viewing spots are within Hawaiʻi Volcanoes National Park: the Kīlauea Overlook above the Halemaʻumaʻu crater, Devastation Trail for panoramic views, and various pullouts along Crater Rim Drive. Rangers mark the best current viewing area with colored flags. Many visitors stay past sunset when lava glows most vividly.

Question 11

How do I plan a trip to see an active volcano eruption?

Accepted Answer

Stay near the park in Volcano village or Hilo (not Kona) to save 45+ minutes each way. Book at least 2 nights to account for possible pause periods in the episode cycle. Plan to stay until after sunset for the best visuals. Bring closed-toe shoes, a windproof jacket (elevation ~4,000 ft), water and snacks, and monitor the live status and webcams before leaving your accommodation.

Question 12

Where do I park during an eruption at Hawaiʻi Volcanoes National Park?

Accepted Answer

The main lots are at the Kīlauea Visitor Center and at various overlooks along Crater Rim Drive. Parking fills quickly during active eruptions — aim for weekday mornings or after 7 PM to avoid peak crowds. Roadside parking is not permitted inside the park; use designated lots and follow signage.

Question 13

What are the hours of Hawaiʻi Volcanoes National Park?

Accepted Answer

The park is open 24 hours a day, 365 days a year, with staffed entrance gates throughout the day. The Kīlauea Visitor Center is typically open until 5 PM. Some areas may temporarily close due to poor visibility or high gas concentrations. Many visitors arrive in the late afternoon and stay into the evening when lava glows most vividly.

Question 14

How much is the entrance fee to Hawaiʻi Volcanoes National Park?

Accepted Answer

As of 2025: Vehicle pass $35 (valid 7 days), walk-in or bicycle $20 per person, annual park-only pass $55, America the Beautiful Annual Pass $80 (valid at all U.S. national parks). The America the Beautiful pass offers free entry and excellent value if visiting multiple national parks on your trip.

Question 15

What should I bring to see a volcano eruption?

Accepted Answer

Per Hawaiʻi Volcanoes National Park, bring: a headlamp or flashlight (for night visits), sturdy closed-toe shoes (for uneven terrain), warm clothes (it can get chilly, especially at night), a rain jacket or poncho (weather can change quickly), glasses and a hat (to protect from volcanic ash), a water bottle (stay hydrated), snacks (for energy), a camera or smartphone (for photos), sunscreen (even on cloudy days), binoculars (for a closer view), a first aid kit or medications (just in case), and a park map (for navigation and safety). Note: Pets are not allowed at overlooks or trails but are permitted in parking lots and roadways — all pets must be leashed at all times. Service animals are allowed in all public areas.

Question 16

What is the current Kīlauea alert level?

Accepted Answer

Kīlauea's current alert level and aviation color code are shown live at hawaii-watch.com. WATCH (aviation: ORANGE) means heightened or escalating unrest with increased potential of eruption. WARNING (aviation: RED) means eruption underway with significant hazards. USGS updates these levels as conditions change.

Question 17

What does a WATCH alert level mean for Kīlauea?

Accepted Answer

A WATCH alert level from USGS means heightened or escalating unrest with increased potential of eruption, or that an eruption is underway with limited hazards. It is the second-highest of four alert levels (NORMAL, ADVISORY, WATCH, WARNING). Aviation color code ORANGE accompanies WATCH status.

Question 18

How often does USGS update Kīlauea volcano status?

Accepted Answer

USGS Hawaiian Volcano Observatory (HVO) typically publishes daily updates each morning Hawaii Standard Time. During active eruptions, additional updates may be issued. Hawaii Volcano Watch aggregates this data and refreshes every 5 minutes at hawaii-watch.com.

Question 19

Where can I watch the Kīlauea eruption live?

Accepted Answer

Live webcam feeds of Kīlauea's summit and rift zones are available at hawaii-watch.com/volcano/webcams. These streams are sourced from USGS Hawaiian Volcano Observatory cameras positioned around Halemaʻumaʻu crater.

Question 20

What is the aviation color code for Kīlauea?

Accepted Answer

Kīlauea's current aviation color code is ORANGE, meaning heightened unrest with increased likelihood of eruption, or eruption underway with minor ash emissions. ORANGE is the second-highest aviation code. Pilots and airlines monitor this code as volcanic ash can affect aircraft safety.
