KWcam images comparing first 2 weeks of Halema‘uma‘u crater eruption

KWcam webcam images compare the changes within Halema‘uma‘u crater since the eruption at Kīlauea Volcano’s summit started two weeks ago. The left image, taken on December 21 at 7:02 a.m. HST, shows the west vent (lower center) and north vent (center left) both erupting lava that is cascading into the new lava lake. In the right image from this morning, January 4 at 9:30 a.

Kīlauea Volcano 2020-2021 summit eruption

An eruption at Kīlauea's summit has significantly changed Halema‘uma‘u crater over the past five months, as documented in these KW webcam images. The first image was taken on December 21, 2020, just after 6:30 a.m. HST and the morning after the eruption began

Changes at Halema`uma`u Over Time

This is a comparison of photos taken from the same location in the Volcano House on May 19 and June 13, 2018. The focal length of the lens for each photo is almost the same. The photos show the enlargement of Halema‘uma‘u laterally and vertically. Note how much lower the rim is relative to the tree in the lower photo.

[HTcam] Halemaʻumaʻu Overlook Vent Thermal from Halemaʻumaʻu Overlook

This image is from a temporary thermal camera located on the south rim of Halemaʻumaʻu and looking steeply toward the north at the active Halemaʻumaʻu vent. The temperature scale is in degrees Celsius up to a maximum of 500 degrees (932 degrees Fahrenheit) for this camera model, and scales automatically based on the maximum and minimum temperatures within the frame.

Recent changes at Kīlauea volcano - October 4, 2021

The USGS Hawaiian Volcano Observatory KWcam at Kīlauea's summit has captured changes within Halemaʻumaʻu crater, at Kīlauea's summit, due to the eruption that began 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

Kīlauea Volcano continues to erupt from the episode 52 and 53 vents on the flank of the Pu`u `O`o cone on the East Rift Zone. For the past several weeks, the lava flow has been confined within a tube system that extends from the vent area to the coast at Kamoamoa.

Volcano mapping among most detailed on Earth...
October 15, 1993

Geologic mapping has come a long way since the first map accurately showing the locations of lava flows on the Island of Hawai`i was published by Stearns and Clark in 1930. A more detailed geologic map of the entire island was produced by Stearns and McDonald in 1946. 

How does East Hawaii get vog?...
October 10, 1993

Over the past several weeks, many east Hawaii residents have noticed the high frequency of days with poor air quality. People traveling on Highway 11 through the Glenwood/Volcano area have encountered such severe bog that they had to turn on their car lights to navigate through the hazy gloom.

In a double handful of molten magma (weighing about a pound), there is less than a tenth of an ounce, by weight, of dissolved gas - roughly the same weight as a pinch of table salt. Yet this tiny amount of gas can drive spectacular lava fountains hundreds of feet into the air.

September 24, 1993

The ongoing eruption on Kīlauea's East Rift Zone has continued with little change for the last month. Lava is erupting from both the episode 51 and 53 vents, both located on the southwest flank of the Pu`u `O`o cone.

The Center for the Study of Active Volcanoes at the University of Hawai`i in Hilo and the U.S. Geological Survey's Hawaiian Volcano Observatory sponsored a public symposium on the prediction and mitigation of volcanic eruptions and earthquakes about a month ago. One of the topics mentioned at the symposium was the role of scientists and of other public officials.

Several weeks ago, on August 12, the Center for the Study of Active Volcanoes at the University of Hawai`i at Hilo and the U.S. Geological Survey's Hawaiian Volcano Observatory held a public seminar on the prediction and mitigation of volcanic eruptions and earthquakes.

August 27, 1993

The eruption on Kīlauea's East Rift Zone continues with lava flowing into the sea at Kamoamoa. Lava is fed to the ocean in underground tubes from two erupting vents on the south and west sides of the Pu`u `O`o cone.

August 20, 1993

Hawai`i had five felt earthquakes in the last two weeks. The activity included a magnitude 3.7 shock at 12:29 a.m. on August 12. This earthquake was located offshore from Kawaihae at a depth of nearly 34 miles.

One of the tools we use to determine the likelihood of future eruptions and earthquakes is to measure changes in the shape of the ground surface.

A symposium will be held this week on Thursday from 8:30 a.m. to 4:30 p.m., at the University of Hawai`i at Hilo, Campus Center Rooms 306 and 307, with scientists, government officials, and the public participating in broad-ranging discussions about volcanic eruptions and earthquakes in Hawai`i.
