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.

Kilauea 61g lava flow ocean entry widens

The flow is entering the sea at several places near Kamokuna, building an increasingly large lava delta at the base of the sea cliff.

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.

During today's overflight of Kīlauea Volcano's "61g" lava flow, the ocean entry appeared less robust, with only one small flow of active lava streaming over the sea cliff. The second, smaller ocean entry point, west of this main entry (noted in our July 29 photo), was not active at the time of the overflight. Photo taken Tuesday, August 2, 2016 courtesy of USGS/HVO

Kilauea’s 61g lava flow ocean entry is slowing, breakouts continue on land

The western portion of the ocean entry was not active during observations yesterday, such that its span was narrowed to about 492 feet since July 29.

This morning, slow-moving pāhoehoe lava toes and lobes continued to break out from the active flow that crossed the "emergency route" gravel road on Kīlauea Volcano's south flank. Viewing these active breakouts requires a long (8-10 miles, round trip) and hot hike. It is essential for anyone attempting the hike to carry 2-3 quarts of drinking water per person. Sturdy shoes and sun protection (hat, sunglasses, sunscreen) are highly recommended. Early morning or late evening hikers should also carry a flashlight and extra batteries. For more safety info, please visit http://pubs.usgs.gov/fs/2000/fs152-00/ and https://www.nps.gov/havo/learn/photosmultimedia/lava-safety-video.htm Photo taken Saturday, July 30, 2016 courtesy of USGS/HVO

Visitors to the active lava flow should be prepared for a long, hot and dusty hike

Viewing the active breakouts requires a long (8-10 miles, round trip) and hot hike. Hawaii Volcanoes National Park is waiving their entrance fee on Monday (Aug 1) to celebrate the centennial of their establishment.
