Virtual flyover of Kīlauea summit

An overflight on December 18 provided aerial photographs of Kīlauea caldera, which were used to construct a 3D model. The water pond is visible in the deepest portion of Halema‘uma‘u crater. For scale, the water pond is 189 m (650 ft) long and approximately 600 m (1970 ft) below the western caldera rim.

How Our Reefs Protect Us: Valuing the Benefits of U.S. Reefs (AD)

The degradation of coastal habitats, particularly coral reefs, raises risks by increasing the exposure of coastal communities to flooding hazards during storms. The protective services of these natural defenses are not assessed in the same rigorous economic terms as artificial defenses, such as seawalls, and therefore often are not considered in decision-making. Here we

HVO now tracking ponds of water, not lava, at Kīlauea's summit
August 8, 2019

The recent appearance of water at the bottom of Halema‘uma‘u, a crater at the summit of Kīlauea Volcano, has attracted wide attention and generated many questions. To understand the significance of this water, we must first gather accurate information on its behavior.

USGS Hawaiian Volcano Observatory (HVO) scientists usually base their research on observations, either visual or instrumental. Interpretations come from these observations, so they must be as good as possible. Incorrect observations can, and have, led to erroneous interpretations.

In ongoing media coverage of demonstrations at the base of Mauna Kea, many hundreds of people can be seen standing on a black lava flow that surrounds the Pu‘uhuluhulu Native Tree Sanctuary adjacent to the Daniel K. Inouye Highway. That same lava flow continues on the other side of the highway, which traverses the saddle between Mauna Loa and Mauna Kea.

One year ago, activity on Kīlauea Volcano was remarkably different than it is today. Lava was flowing toward the sea, robust ocean entry plumes were fumigating coastal areas, and island air quality was impacted by huge amounts of volcanic gases and particles.

On July 2, HVO raised the Volcano Alert Level for Mauna Loa from "Normal" to "Advisory".

July 11, 2019

Shortly before midnight on July 5, 1975, Mauna Loa Volcano awakened with a shudder. Quickly responding to a seismic earthquake/tremor alarm at 11:18 p.m., USGS Hawaiian Volcano Observatory (HVO) staff rushed to their offices, where, at 11:42 p.m., they noted red glow above the mountain. The 1975 eruption lasted less than a day, but it ended Mauna Loa's then longest-known repose period.

Hawaii residents are likely familiar with the Volcano Activity Updates that the Hawaiian Volcano Observatory (HVO) issues for Kīlauea and other active Hawaiian volcanoes. These updates, which provide situational awareness of volcanic activity and hazards, were formally established in 2006.

Kīlauea Volcano, on the Island of Hawai‘i, has two rift zones. The East Rift Zone is longer, with 50 km (about 31 miles) on land plus another 80 km (about 43 miles) below sea level. The Southwest Rift Zone, which is historically less active, is 40 km (about 20 miles) long with only a small portion underwater.

Since the early 1990s, scientists have used radar satellites to map movement, or deformation, of Earth’s surface. Interferometric Synthetic Aperture Radar (InSAR) calculates the difference between two radar images acquired by an orbiting satellite taken at different times but looking at the same place on Earth.
