January 5, 2021—Kīlauea summit topographic changes

Topography of Halema'uma'u crater, at the summit of Kīlauea Volcano, on December 26, 2020 (left), and January 5, 2021 (right). These Digital Elevation Models (DEMs) are created from aerial imagery collected during helicopter overflights. They show that the lava lake within Halema'uma'u continues to rise and deepen. Eruptive vents are evident on the wall of Halema'uma'u,

View looking north across Kīlauea caldera from the south rim of Halema‘uma‘u, showing the ongoing eruption around 5:30 p.m. HST on January 5, 2021. The west vent activity included the “dome fountain,” effusive lava flows from a mid-elevation vent, and weak strombolian spattering activity from the high-elevation vent. USGS photo by K. Lynn.

Image of the Week - Fires Tear Through Former Cane Fields

The waves of sugar cane that once defined the Hawaiian island landscape of Maui, have slowly given way to non-native annual grasses in recent decades. Those grasses have become a fire hazard along the way.

The closure of central Maui's last large cane mill in 2016 opened up some 36,000 acres for new growth. Some of those acres burned in 2019 during one of the island

Channel crusting over at the base Halema'uma'u's west vent

The west vent in Halema‘uma‘u crater continues to erupt at Kīlauea’s summit. These telephoto images from December 29 (left) and December 30 (right) compare the lava lake surface below the west vent. The west vent is supplying lava to the lake through a crusted over channel, which was starting to form by December 30. USGS photos by H. Dietterich.

At Halema‘uma‘u, the west vents (visible in the foreground of this photo as two glowing holes on a cone-shaped feature) erupt occaisional spatter. Lava is also emerging in a small dome fountain above the lake crust in front of the west vents, probably from a submerged portion of the vent (visible in the background of this photo as a bright spot with lava crust boundaries

Dome Fountain Formed at Lava Lake Inlet, Halema'uma'u (Jan 2-3, 2020)

Lava forms a “dome fountain” at the inlet to the lava lake in Halema'uma'u crater January 2-3, 2021. Lava from the western vent cascades beneath roofed vertical channels to enter the lava lake at an inlet that has become partially submerged. The result is a rolling upwelling of lava near the inlet called a “dome fountain.”

Dome fountains have been observed during

In the land of Kamehameha, south of Kona on the big island of Hawaii, a sacred landscape called Puʻuhonua O Hōnaunau faces the uncertainty of the rising seas.

The bones of royal chiefs rest there. Stories of how ancient Hawaiian lawbreakers flocked to this place of refuge still resonate throughout the 180-acre national historic park that surrounds Hōnaunau Bay.

What does water in Halema‘uma‘u mean
August 15, 2019

The slowly deepening pond of water on the floor of Halema‘uma‘u, the first in recorded history, has captured the interest of media and the public, both locally and nationally. Many questions are being asked. The two most frequent are, where is the water coming from and what is its importance?
