Volcano Watch: Kīlauea Volcano’s “Old Faithful”—a thing of the past

The Island of Hawai‘i once had its own “Old Faithful,” composed of lava rather than boiling water, located in Halema‘uma‘u Crater at the summit of Kīlauea.

Volcano Watch: Kilauea activity update for August 25, 2016

Kīlauea continues to erupt at its summit and East Rift Zone. During the past week, the summit lava lake level varied between about 20 m and 40 m (66–131 ft) below the vent rim within Halema‘uma‘u Crater.

Halemaumau lava lake rises to highest levels since May 2015

The lava lake surface level has risen and is approximately 20 m (66 ft) below the crater rim. This is among the highest measured levels of the lake since May 2015.

People who venture too close to Kīlauea's Kamokuna ocean entry—by land or by sea—are at risk from multiple hazards associated with lava flowing into the sea. The white plume formed by the interaction of lava and seawater is a corrosive mixture of super-heated steam, hydrochloric acid, and tiny particles of volcanic glass, all of which should be avoided. Lava deltas (new land formed at the ocean entry) can collapse without warning. Should the lava delta shown here collapse, fragments of molten lava and blocks of hot rock would be thrown both inland and seaward, potentially impacting people on the cliff above the ocean entry and in the boat in front of the delta.

The summit lava lake in Halemaʻumaʻu Crater continuously circulates, with lava upwelling on one side of the lake and downwelling on the opposite side, often resulting in vigorous spattering (bright spot on left side of lake). As it circulates, sections of the dark-colored, semi-solid lake surface pull apart, revealing the incandescent molten lava beneath and creating the appearance of a jigsaw puzzle. This evening, the lava lake surface was about 26 m (85 ft) below the vent rim. The silhouette of Mauna Loa is visible in upper right. Photo taken Wednesday, July 27, 2016 courtesy of USGS/HVO

The active lava flow on Kīlauea Volcano's south flank crossed the emergency access road in Hawaiʻi Volcanoes National Park this afternoon around 3:20 p.m., HST, providing wonderful lava-viewing experiences for Park visitors. A section of the road can be seen here, with fume from the active lava tube in the far distance behind it, and the active flow front in the foreground. The flow front continued to advance, and was less than 100 meters (yards) from the ocean a few hours later (when this photo was taken). The lava flow reached the ocean about 01:15 a.m. July 26.
