Volcano Watch: Kilauea activity update for November 15, 2018

Kīlauea is not erupting. Low rates of seismicity, deformation, and gas release have not changed significantly over the past week.

September 19, 2018 USGS photo looking southward of the south caldera of Kīlauea Volcano showing the main collapse area. The south Sulphur Bank is in the left side of the photo. Uēkahuna Bluff, from where this photo was taken, cuts across the bottom and lower right corner of the photo. After the collapse of 1868, the caldera floor may have looked something like this.

Volcano Watch: A summit collapse 150 years ago had similarities to the 2018 collapse

Kīlauea summit collapses accompanied by lava lake draining are a routine part of the long-term refilling of the current caldera produced centuries ago.

Kīlauea Volcano's summit, as viewed from the southwest, shows the collapsed area of Halema‘uma‘u and the adjacent caldera floor. A section of Crater Rim Drive preserved on a down-dropped block is visible at the far right. Volcanic gases rising from magma stored beneath the summit continue to escape to the surface, as they have for as long as Kīlauea has existed, resulting in deposits of sulfur on the crater walls.

A slight inflationary trend near and east of Puʻu ʻŌʻō suggests that magma may be refilling the middle East Rift Zone. Low seismicity and reduced gas emissions do not indicate that the magma is shallow, but HVO continues to closely monitor this area and will report any significant changes.

Bright red polygon features were drawn by USGS Geographic Information Systems (GIS) analysts around new or active lower East Rift Zone lava flows, which appear lighter in color due to their high temperature on this thermal map. Collected during a helicopter overflight on May 9, 2018, this map shows fissures 6 (left) and 15 (right) with Pohoiki Road passing between the two vents. USGS map.

Volcano Watch: How are lava-flow maps made during an eruption?

Computer programs known as Geographic Information Systems (GIS) have been the preferred tool of USGS cartographers for many years. Using commercial GIS software, the user creates a stack of “layers,” such as labels, roads, and political boundaries that together form a map.

Volcano Watch: Kīlauea 2018 events mark a watershed for volcano science

The 2018 summit collapse and lower East Rift Zone eruption at Kīlauea Volcano were dramatic and, for many Island of Hawaiʻi residents, tragic events. As with all eruptive crises, these events offered exceptional opportunities to learn more about how volcanoes work and to answer some “bigger picture” questions.

Volcano Watch: Kīlauea hazard assessments include analyses of salts on volcanic ash

Upon contact with water, either through ash falling into water catchments or by rain falling on ash, the soluble components are washed from the ash.

Low sulfur dioxide gas emissions on Kīlauea have resulted in greatly diminished vog (volcanic air pollution) in Hawaii, giving rise to spectacular views on the island. Here, looking across the field of lava erupted from Kīlauea's lower East Rift Zone this past summer, the shield-shaped profiles of Mauna Loa (left) and Mauna Kea (right) can be clearly seen in the far distance.
