An Endangered Honeycreeper, the `Akeke`e (Kauai Akepa), 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

Frequently Asked Questions about Deformation at Kīlauea Summit

At present, the summit of Kīlauea Volcano is undergoing dramatic changes. The caldera floor is subsiding. The rim and walls of Halemaʻumaʻu are slumping inward. Nearby residents feel moderate-sized earthquakes, and see small ash plumes rise from the crater. The responses to these Frequently Asked Questions address the reasons behind the current activity at Kīlauea Volcano’

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.

This month marks the 72nd anniversary of the last large explosive eruption of Kīlauea Volcano. The atypical "Hawaiian" eruption occurred in Halema'uma'u Crater when groundwater came into contact with hot rocks surrounding the magma.

As geologists working at the Hawaiian Volcano Observatory, we give many talks about the current eruption of Kīlauea, and people in the audience typically ask lots of questions about how volcanoes behave and how we attempt to predict that behavior.

Last week scientists at the U.S. Geological Survey's Hawaiian Volcano Observatory (HVO) began their annual ground deformation surveys at the summit of Mauna Loa Volcano. Comprehensive monitoring of ground deformation and earthquake activity (seismicity) provides the most reliable criteria for forecasting volcanic eruptions.

When visitors to this island arrive at the Keahole airport and travel along the Queen Ka'ahumanu highway to a hotel in south Kohala, they cannot help but notice the bare, black, glistening fields of lava. The flows, with their glassy surfaces, appear to have erupted yesterday.

Monday, March 11, marks the anniversary of the last of a series of dramatic collapses at Kīlauea summit. On three occasions in February and March 1960 the floor of Halemaumau Crater broke apart and collapsed inward, raising a roiling black column of steam and rock dust 500 feet in the air.
