Volcano Watch — Lava from Kīlauea's East Rift Zone lessens

The 10-year-long eruption on Kīlauea's East Rift Zone continues, with the only change being a decrease in eruption rate over the last few weeks. This decrease in rate correlates with the slowly deepening surface of the lava pond inside the Pu`u `O`o cone, as reported last week.

Volcano Watch — Eruption's flows continue, danger remains

The eruption on Kīlauea's East Rift Zone continues with little change. The episode 51 and 53 vents on the southwest flank of the Pu`u `O`o cone continue to feed lava directly into a tube system that transports the lava to Palama Pali and beyond, to the ocean entries at Kamoamoa.

Volcano Watch — Kīlauea gas emissions far greater than from geo wells

Volcanoes around the world emit a variety of gases in different proportions, with the main components invariably being carbon dioxide, water, and sulfur dioxide. Minor components include, but are not limited to, hydrogen gas, carbon monoxide, hydrochloric acid, hydrofluoric acid, methane, and hydrogen sulfide.

Volcano Watch — Not all eruptions as passive as this

Kīlauea is famous for eruptions of the type we are now experiencing - quiet effusion of lava that makes the eruption approachable. However, not all of Kīlauea's eruptions have been so passive and approachable.

Volcano Watch — Current lava flows contrast with violent eruptions of the past

The 10-year-long eruption along Kīlauea's East Rift Zone continues with little change. Active flows travel underground to the ocean in lava tubes from the eruptive vents on the south and west sides of the Pu`u `O`o cone.

The episode 51 vents on the west flank of Pu`u `O`o were active from April 23 at about 11:00 a.m. until April 28 at 11:30 a.m., when the eruption stopped once again. Since then, the lava lake inside Pu`u `O`o vent has risen from about 140 to between 120 and 130 feet below the rim of the crater.
