Kilauea Volcano Guide: Current Activity, Safety, History & Best Viewing Spots
Kilauea volcano anchors the dynamic heart of Hawaiʻi Volcanoes National Park. This modest rise on Mauna Loa's southeast flank might go unnoticed were it not for its vast steaming crater and the iconic Halemaʻumaʻu, a crater-within-a-crater that has unleashed near-continuous lava flows for over 25 years.
Early researchers mistook Kilauea for a mere vent of Mauna Loa, but it hosts its own distinct, highly active magma system—dating back as far as 600,000 years. Activity levels during your visit depend on Pele, the Hawaiian goddess of fire and volcanoes who resides here. Keep expectations modest and prepare for awe-inspiring surprises.
Is Kilauea Currently Erupting?
As the most active of Hawaii's Big Island's five volcanoes, Kilauea rarely disappoints. Visitors to Halemaʻumaʻu often witness (and smell) ongoing action. The dramatic 2018 eruption ended with a caldera collapse, hurling ash 30,000 feet high. Activity resumed in December 2020 with less intensity. Check the USGS Hawaiian Volcano Observatory for daily updates: USGS Kilauea Reports.
Is Kilauea Safe to Visit?
Despite its intensity, Kilauea remains safe for visitors. The 2018 event caused property damage and minor injuries but no deaths. Active vents like Halemaʻumaʻu and Puʻu ʻŌʻō emit tons of volcanic gases daily. Lava-ocean interactions produce "laze"—a hazardous steam plume of sulfuric and hydrochloric acids mixed with glass particles—leading to vog (volcanic smog). Winds can carry vog across the park. Those with respiratory issues, heart conditions, pregnant individuals, infants, and young children should exercise caution during eruptions. Monitor air quality at Hawaii SO2 Network.
A Brief History of Kilauea
On March 19, 2008, Halemaʻumaʻu broke decades of quiet with a massive steam explosion, scattering rocks and Pele's hair (volcanic glass strands) across 75 acres. Subsequent blasts enlarged a 300-foot vent, now often filled with a pulsing lava lake that overflows into Kilauea Caldera. Lucky visitors might catch rare spatter from the closed Crater Rim Drive section.
Missionary William Ellis's 1823 description of the "boiling goblet" drew global adventurers. Mark Twain, in 1866, marveled: "Circles and serpents and streaks of lightning... Vesuvius is a mere toy compared to this." In 1924, explosive eruptions doubled the crater's size to 300 feet deep and 3,000 feet wide. Halemaʻumaʻu has since erupted 18 times, solidifying its status as Kilauea's summit hotspot.
Halemaʻumaʻu is Pele's sacred home, revered across Hawaiian culture.
