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

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

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.

The 10-year-long eruption on Kīlauea's East Rift Zone continues with lava flowing from the vents on the south and west sides of Pu`u `O`o to the sea in underground tubes.

The 10-year-long eruption on Kīlauea's East Rift Zone continues, with the only change being a decrease in eruption rate over the last few weeks. This decrease in rate correlates with the slowly deepening surface of the lava pond inside the Pu`u `O`o cone, as reported last week.

The largest earthquake in Hawai`i since January 26 occurred at 2:58 a.m. Tuesday. Many residents were awakened by the shaking from this magnitude-4.9 earthquake. The Jan. 26 earthquake, which occurred beneath Pahala, had a comparable magnitude.

The eruption on Kīlauea's East Rift Zone continues with little change. The episode 51 and 53 vents on the southwest flank of the Pu`u `O`o cone continue to feed lava directly into a tube system that transports the lava to Palama Pali and beyond, to the ocean entries at Kamoamoa.

A magnitude 3.0 earthquake was widely felt in the Hilo area on Thursday afternoon at 1:45 p.m. The earthquake was about 25 miles deep and was located offshore about 10 miles east of Hilo.

Volcanoes around the world emit a variety of gases in different proportions, with the main components invariably being carbon dioxide, water, and sulfur dioxide. Minor components include, but are not limited to, hydrogen gas, carbon monoxide, hydrochloric acid, hydrofluoric acid, methane, and hydrogen sulfide.

Kīlauea is famous for eruptions of the type we are now experiencing - quiet effusion of lava that makes the eruption approachable. However, not all of Kīlauea's eruptions have been so passive and approachable.

The 10-year-long eruption along Kīlauea's East Rift Zone continues with little change. Active flows travel underground to the ocean in lava tubes from the eruptive vents on the south and west sides of the Pu`u `O`o cone.

The episode 51 vents on the west flank of Pu`u `O`o were active from April 23 at about 11:00 a.m. until April 28 at 11:30 a.m., when the eruption stopped once again. Since then, the lava lake inside Pu`u `O`o vent has risen from about 140 to between 120 and 130 feet below the rim of the crater.

The 10-year-long eruption on Kīlauea's East Rift Zone continues with little change. During the week, the lavaentries into the ocean consolidated to three main entries on the east and west edges of the Kamoamoa flow and near the west edge of the Lae`apuki flow.
