KW webcam shows that Halema‘uma‘u lava lake island rotated

The KW webcam continues to document activity in Halema‘uma‘u crater at Kīlauea's summit. The webcam is located on the west rim of the crater, and looks to the east across Halema‘uma‘u (in the images, north is to the left and south is to the right). The first image, taken at just after 6:30 a.m. HST on December 27, 2020, HST shows the largest island in the lava lake

Children pose with 8 ton ballistic block at Kīlauea, Hawai‘i.

Some of the large ballistic blocks from the Kīlauea eruption of 1924 later became visitor attractions. Many of these blocks remain in place today as evidence of the forces unleashed at Kīlauea during the eruption of 1924.

An Endangered Honeycreeper, the `Akikiki (Kaua`i Creeper), in Hawaii

Many species of Hawaiian honeycreepers have persisted into the 20th century because high elevation rain forests on the islands of Kaua’i, Maui, and Hawai’i are cool enough to limit transmission of introduced avian malaria (Plasmodium relictum). Malaria transmission is tied closely to the effects of temperature on development of malarial parasites within their

July 17, 1992

The episode 51 vents adjacent to Pu`u `O`o on the East Rift Zone of Kīlauea Volcano have been in continuous eruption since before dawn on June 21. Until this period, episode 51 has been characterized by off-and-on activity since it began on March 7. The current eruptive interval is by far the longest and most stable since that time.

The Hawaiian Volcano Observatory has joined forces with the University of Hawai`i to promote the collaborative study of volcanoes with the initiation of a new Hawai`i Center for Volcanology. On Tuesday this new center was officially announced during a press conference held in Honolulu on the university campus.

HVO maintains wide seismic network on the Big Island...
July 3, 1992

The Hawaiian Volcano Observatory maintains a network of about 50 seismic stations on the Island of Hawai`i. The purpose of the network is twofold: to define the regional seismicity of the Island of Hawai`i, and to distinguish and study earthquakes as they relate to major fault zones and to the eruption and intrusion of magma. 

Current eruption continuing at low levels...
June 26, 1992

We will cover activity during the last two weeks, since we missed our deadline last week. The episode 51 vents on the west flank of Pu`u `O`o, which began erupting on Wednesday, June 10, shut down on June 16. The vents were then inactive until Sunday, June 21, and have continued to be active through June 26.
 

Kīlauea's not Hawaii's only active volcano...
June 12, 1992

The volcanic hazards posed by Kīlauea Volcano are obvious to everyone who sees the active eruptions and visits Hawai`i Volcanoes National Park, where the starkness of much of the volcanic landscape is a testament to the recency of activity. 

Volcano slides are often the cause of strong earthquakes...
June 5, 1992

Moderate to large earthquakes located beneath the south flank of Kīlauea Volcano are commonly caused by seaward sliding of that part of the volcano. On Friday, May 29, at 2:03 p.m., a 3.3-magnitude earthquakeoccurred about five miles deep and 15 miles offshore from Kīlauea's shoreline. 

Eruption episode remains unpredictable...
May 29, 1992

The episode 51 vents on the west flank of Pu`u `O`o, which stopped erupting on May 22, began erupting again on Wednesday morning sometime shortly before dawn. This eruptive interval was extremely vigorous on Wednesday and Thursday, but stopped Thursday during the night.

May 22, 1992

The episode 51 vents on the west flank of Pu`u `O`o which were inactive for six days starting Tuesday, April 28, were in continuous eruption since Monday, May 4, starting at about noon, until Friday afternoon. During this 18-day interval, the eruption was nearly constant in level of activity, as seen in tremor of nearly constant amplitude.
 

Episode 51 vents now mostly inactive...
April 24, 1992

The episode 51 vents on the west flank of Pu`u `O`o were inactive most of this past week. Last Sunday afternoon, the flows had advanced about one mile south of the vents and burned about 150 acres of forest.

April 17, 1992

The eruption at the episode 51 vents on the west flank of Pu`u `O`o continued without interruption again this week. The eruption is little changed from a week ago, when we reported that a lava pond had formed just west of the vent. The pond is overflowing and sending a surface-fed pahoehoe flow to the south.

April 10, 1992

The eruption at the episode 51 vents on the west flank of Pu`u `O`o continued without interruption this week. A lava pond has formed just west of the lower vent. This pond fills and overflows during periods of high-volume eruption, but most of the time flows are fed through tubes in the sides of the pond. The main flow from the pond has been toward the west.
 

Lava flow continues in starts and stops...
April 3, 1992

Last week we noted that, based on the activity in the pond inside Pu`u `O`o cone, the lull in activity at the episode 51 vent was probably just another pause in episode 51. Sure enough, the vent again began erupting Sunday morning about 9:30 a.m., or about the time you were reading about the eruption in last Sunday's paper.
