New eruption at Kīlauea Volcano - September 29, 2021

The USGS Hawaiian Volcano Observatory KWcam at Kīlauea's summit has captured the onset of a new eruption within Halemaʻumaʻu crater on September 29, 2021. At approximately 3:21 pm, HST, new fissures opened at the base of Halemaʻumaʻu crater. These fissures opened east of the large island near the center of the lava lake that was active within Halemaʻumaʻu crater from

The webcams are operational 24/7 and faithfully record the dark of night if there are no sources of incandescence or other lights. Thermal webcams record heat rather than light and get better views through volcanic gas. At times, clouds and rain obscure visibility. The cameras are subject to sporadic breakdown, and may not be repaired immediately. Some cameras are

This image is from a temporary research camera positioned on the north rim of Mokuʻāweoweo, the summit caldera of Mauna Loa volcano by the USGS Hawaiian Volcano Observatory. If you look carefully around early morning or late evening, you may see a few thermal areas emitting steam. See 'Current Activity' for the latest Mauna Loa information.

An endangered Hawaiian hoary bat, a species that is sometimes killed by wind turbines. USGS scientists from Hawaii and Colorado are devising a way to directly observe bat occurrence and behavior at wind turbines using a video system composed of high-powered illuminators and near-infrared cameras.  This new approach images the full rotor-swept areas of wind turbines for

Lava continues to flow near Kamoamoa...
November 20, 1992

The eruption from the episode 51 vents has continued without interruption since October 2. The flows crossed the Chain of Craters Road near Kamoamoa in Hawai`i Volcanoes National Park on November 7. Since that time, flows have covered all of the Kamoamoa ruins, campground, parking lot, and picnic area, and have formed perhaps 30 acres of new land.
 

Volcano watchers should beware...
November 6, 1992

The eruption from the episode 51 vents has continued without interruption since October 2. The flows have now advanced to within 300 feet of the Chain of Craters Road inside Hawai`i Volcanoes National Park. The flows advanced over the pali during the last week-and-a-half and came within a quarter of a mile of Chain of Craters Road by early this week.

October 30, 1992

The 10-year long eruption of Kīlauea Volcano continues from the episode 51 vents located on the west flank of the Pu`u `O`o cone. The flows advanced slowly from October 3 until October 28, when they began to flow over the pali above Kamoamoa.

The Hawaiian Volcano Observatory studies mainly the current activity of Hawai`i's volcanoes, and our eruption forecasts are limited to the short-term future (hours, days, months, sometimes a few years). 

Quake starts Kīlauea off on a busy two weeks...
October 16, 1992

The last two weeks have been particularly busy on Kīlauea Volcano. On October 2, starting about 3:30 p.m., the tremor near Pu`u `O`o began to increase, and it appeared as if another phase of the episode 51 eruption would be under way soon.

USGS
October 2, 1992

Over the years, scientists at the Hawaiian Volcano Observatory have developed good techniques for short-term eruption predictions (a few hours to a few days' warning) for Kīlauea and Mauna Loa Volcanoes. However, our capabilities for long-term predictions consist predominantly of educated guesswork. 

New map defines lava flow hazard zones on the Big Island...
September 25, 1992

The U.S Geological Survey has recently published a new, full-sized map which defines the boundaries of nine lava flow hazard zones on the island. This map is an updated version of the page-sized map included in the USGS booklet Volcanic and Seismic Hazards on the Island of Hawaii published in 1990. 

Eyewitness accounts tell terror of huge quake in 1868...
September 18, 1992

Residents of Pahala felt a small earthquake (magnitude 3.7) at 10:22 p.m. on September 10. This earthquake was located a few miles northwest of the town and about 6 miles deep. Although the earthquake caused no damage, this was the site of the largest historic earthquake in Hawaii, which occurred in 1868.

"With all the lava being erupted, is there a large, empty space within the Earth where the lava came from?" This is a frequent question answered by the staff of the U.S. Geological Survey's Hawaiian Volcano Observatory, and the answer is "no."
 

Kīlauea vents active but lava has slowed...
September 7, 1992

The episode 51 vents have been continuously active since early in the morning on July 27. The active vents are located just west of the Pu`u `O`o cinder and spatter cone on the East Rift Zone of Kīlauea Volcano. Episode 51 has been characterized by intermittent activity since it began on March 7.

To the non-geologist, lava is hot, orange molten rock, or when cooled, smooth and gray, or black and jagged rock. However, to the geologist or volcanologist, lava contains a set of clues to decipher processes occurring in the interior of the Earth and the volcano.

USGS
August 14, 1992

The Hawaiian Volcano Observatory's primary purpose is to understand how volcanic systems operate. All of the work we do in defining geological hazards posed by the volcanoes, and short-term monitoring of eruptions and lava flows, is made possible by developing this fundamental understanding of volcanic systems.
