Kīlauea's Volcanic Gases and Their Environmental Impacts

Gas emissions from the crater of Pu‘u ‘Ō‘ō on Kīlauea's east rift zone (foreground) and the summit vent in Halema‘uma‘uCrater (background, just below the clouds) create volcanic pollution that affects the air quality of downwind communities. USGS photo by Tim Orr.

PubTalk 12/2011 — Tracking Ongoing Kilauea Eruptions

--fissures...fountains...and flows

  • Spectacular Kilauea eruptions have produced a summit lava lake, roiling for several years, and a flank eruption recently sending lava flows downslope to threaten residential areas

Active Lava Stream from Pu‘u ‘Ō‘ō

Video showing the fast-moving upper section of the lava stream on the relatively steep eastern flank of Pu‘u ‘Ō‘ō. The video pans to the left to show the smaller lava stream eruption from the lower (eastern) end of the fissure.

Lava Flow From Pu‘u ‘Ō‘ō

Video showing a 6 m (20 ft) high lava cascade near the eastern base of Pu‘u ‘Ō‘ō. This is the same lava stream shown in the previous two videos. The lava stream continues on several hundred more meters (yards) before transitioning into rubbly pāhoehoe and ‘a‘ā and stalling well short of yesterday’s flow front, which is now inactive.

Lava Flow From Fissure Eruption on Kilauea Volcano's East Rift Zone

A new fissure eruption in September 2011 on the east flank of Pu‘u ‘Ō‘ō on Kīlauea Volcano's east rift zone reminds us of the need to be aware of our ever-changing volcanic environment on Hawai‘i Island. The fissure—the source of the lava flow—is shown in this image. Pu‘u ‘Ō‘ō cone and crater are in the background. Aerial view is to the southwest.

On January 3, 2003, Kilauea Volcano, perhaps the world’s most active volcano on the Island of Hawai`i, will have been erupting continuously for 20 years. Since the eruption began in 1983, lava flows have covered 43 square miles of the volcano, added nearly 550 acres to the island, created local volcanic air pollution known as "vog," and drawn millions of people to experience and enjoy volcan

This is the season when the aroma of pine and fir greets KTA supermarket shoppers as they arrive to buy their fish and poi. Although more than 60,000 trees are imported for the Christmas season, Hawai`i is also home to some trees of its own that deserve hearty celebration.
