Volcanologists collaborate on how to best communicate volcanic hazard and risk via long-term assessments at the third Volcano Observatory Best Practices workshop in Vancouver, Washington from November 15th to 18th, 2016.

A young 'ua'u exercises its wings in preparation for its first flight directly out to sea. The 'ua'u, or Hawaiian petrel, is a federally endangered native seabird that nests at high elevations on Mauna Loa volcano.

Foundering of the lava lake crust is common near the lake's margins. The triangular-shaped slab of crust (left of photo's center) was sinking back into the lake as more fluid lava upwelled around it.

The level of the lava lake at the summit of Kīlauea has been high recently, providing good views of spattering from the Jaggar Museum visitor overlook in Hawai‘i Volcanoes National Park. This photo shows activity as viewed from the rim of Halema‘uma‘u Crater (closed to the public since 2008 due to volcanic hazards). Spattering is common, and on Sunday (Nov.

This booklet is one of the many information products available from the Vog Information Dashboard.

A close-up of Pele's hair from Kīlauea Volcano's summit lava lake. X-ray diffraction analyses of the Pele's hair (basaltic glass) collected today will provide information on the mineralogy of Kīlauea lava, which, in turn, can shed light whether the magma supply to the volcano is constant or is changing.

A USGS-HVO scientist collects Pele's hair from the parking area south of Halema‘uma‘u Crater, which has been closed since early 2008 due to ongoing volcano hazards associated with the summit lava lake.

This video shows activity in the summit lava lake in Halema‘uma‘u Crater. Spattering like this is common in the lake, and this video shows the view from the rim of Halema‘uma‘u (closed to the public due to volcanic hazards). This spattering has recently been visible from the Jaggar Overlook inside Hawai‘i Volcanoes National Park (open to the public).

This view shows Kīlauea's summit lava from the south, with the east slope of Mauna Loa in the background and Mauna Kea in the distance. The Hawaiian Volcano Observatory and the Hawai‘i National Park Service Jaggar Museum buildings are visible on the rim of Kīlauea's summit caldera, behind Halema‘uma‘u.

This photo looks south toward the lava lake in Halema‘uma‘u. The April-May 2015 lava flow is not as obvious from this perspective, but the small overflows from October 2016 stand out a bit better. They are visible as shiny pads of lava at the upper left and lower right sides of the lake.

This map shows recent changes to Kīlauea's East Rift Zone lava flow field. The area of the active flow field as of October 19 is shown in pink, while widening and advancement of the active flow as mapped on November 3 is shown in red. There have been no new surface flows and the only change is at the Kamokuna ocean entry.

The lava lake was spattering in two places along its southeast edge at the time this photo was taken. Lava wells up into the lake nears its northern edge, which is out of sight to the left, and generally flows to the south where it sinks back down along the margin of the lake.

The Pūlama pali is one of several steep fault scarps that cut the south flank of the Island of Hawai‘i. This image shows the steepest part of the Pūlama pali as viewed from the coastal plain. The fume on the face of the pali marks the trace of the active lava tube carrying lava to the ocean, which is behind the photographer.

This photo shows the Hawaiian Volcano Observatory and the Hawai‘i Volcanoes National Park Service Jaggar Museum buildings on the summit of Kīlauea Volcano, overlooking the summit caldera. Mauna Loa volcano looms in the background.
