Kīlauea Caldera Thermal from HVO Observation Tower [F1cam]

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

[MLcam] Mokuʻāweoweo Caldera from the Northwest Rim

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.

[KIcam] Kīlauea Caldera from HVO Observation Tower

This image is from a research camera mounted in the observation tower at the Hawaiian Volcano Observatory. The camera is looking SSE towards the active vent in Halemaʻumaʻu, 1.9 km (1.2 miles) from the webcam. For scale, Halemaʻumaʻu is approximately 1 km (0.6 mi) across and about 85 m (~280 ft) deep.

This image is from a temporary thermal camera located on the north rim of Mauna Loa's summit caldera. 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 on the caldera floor and not the whole frame, which sometimes results in the

Slope map of Mauna Loa, including lava flows erupted since 1823 (gray), showing the approximate number of hours or days it took for a flow to advance from the vent location to the ocean or maximum reach of a flow. One flow that moved down the steep slopes on west flank of Mauna Loa reached the ocean in as little as 3 hours after the vent started erupting in 1950. The bold

No episode 52 after all, just repeats of 51...
March 20, 1992

With the wisdom of hindsight, we have concluded that the continuing episodic eruptive activity from the vent on the west flank of the Pu`u `O`o cone is a single episode with pauses, rather than a new episode with each eruption at the vent. We are therefore continuing to call the activity that began on March 7 "episode 51."

Episode 51 stops, 52 begins at Kīlauea Volcano...
March 15, 1992

Episode 51 of the nine-year long eruption along Kīlauea Volcano's East Rift Zone stopped by 4:00 p.m. Thursday afternoon. As we forecast last Sunday, this episode was brief, lasting only from March 7-12.

March 6, 1992

The nine-year long eruption along the East Rift Zone of Kīlauea Volcano took two dramatic turns this past week, but ended up nearly where it started. 
 

Newest episode likely to stop flowing in weeks...
February 27, 1992

Episode 50 began about 7:30 p.m. on Feb. 17 from a small fissure just southwest of the Pu`u `O`o cone. By the 19th, only about 100 feet of the original fissure was still active. The activity has since settled down at one main point near the northeastern end of the fissure. By Friday, this vent had created a spatter cone almost 25 feet high.

February 16, 1992

Since at least April 1991, the volume of lava erupted from the Kupaianaha vent has steadily declined. Since late November, the remaining lava flows have been limited to a single area near the 1,850-foot elevation, less than two miles downslope of the vent.

The internal workings of Mauna Loa Volcano will be probed from space starting this week by a satellite system designed to track military vehicles rather than volcanoes.

January 31, 1992

Kīlauea is the world's most active volcano. About 70% of Kīlauea's surface is covered by lava less than 500 years old and over 90% is covered by lava less than 1,100 years old. Much of the surface of Kīlauea Volcano lies within Hawai`i Volcanoes National Park, where eruptions are generally welcome tourist attractions.

January 24, 1992

A magnitude 3.8 earthquake occurred about 15 miles beneath Mauna Kea Volcano at 1:48 a.m. on January 21. Similar deep earthquakes occur persistently beneath the Big Island but are not restricted to any particular location.

January 17, 1992

The most notable event on Kīlauea Volcano this past week was a swarm of small earthquakes, mainly on January 13. This swarm included two earthquakes with magnitudes larger than 3.0 (see figure) and numerous smaller earthquakes.

January 10, 1992

The eruption on the East Rift Zone of Kīlauea Volcano continues with low-volume, steady effusion of lava from the breakout at about the 1,900-foot level of the tube downslope from the Kupaianaha vent. This is the same area that has had active flows for the last several weeks. Tremor continues at low levels in the upper East Rift, indicating that magma continues to move in the rift zone. 
 

Eruption's 10th year begins...
January 3, 1992

Nine years ago on January 3, 1983, the ongoing eruption on the East Rift Zone of Kīlauea Volcano began when a discontinuous 3.7-mile long series of fissures opened in, and downrift of Napau Crater.

December 27, 1991

Kīlauea Volcano continues to erupt from the Kupaianaha vent on the East Rift Zone. The volume of lava moving down the Waha`ula lava tube from the Kupaianaha vent has decreased slowly since April 1991, with a short sharp decrease and subsequent increase during and after episode 49 in November.
