Spattering is common in the area where lava sinks back into the system, and this photo shows these processes are occurring in a small grotto. In the right portion of the photo, the ledge occupying much of the south part of the Overlook crater is visible.

South winds permitted clear views into the south portion of the Overlook crater, which is often obscured by thick fume. The bright orange area is the location where lava at the surface of the lake sinks back into the system, with spattering and degassing common in this area.

A closer look at the flow extending northeast of Pu‘u ‘Ō‘ō. Pu‘u ‘Ō‘ō cone is at the right edge of the photo, and view is towards the northeast. In the foreground, two sources of fume mark the path of the lava tube supplying lava to the flow front. In the top-left, a few sources of smoke mark where the flow margin is burning moss and lichen on older flows.

This photo looks northeast and shows Pu‘u ‘Ō‘ō crater. Recent activity has been focused around a few spatter cones on the crater floor. At the far edge of the crater, a small lava pond has been active and has been the source of flows extending northeast of Pu‘u ‘Ō‘ō. Those flows are visible at the top-center of the photo.

An active lava lake is contained within the Overlook crater, within Halema‘uma‘u Crater at the summit of Kīlauea Volcano. The summit eruption began on March 19, 2008, and is now nearly five years old. The Hawaiian Volcano Observatory and Jaggar Museum are visible as a small bump on the horizon in the upper right portion of the image.

Participants at the 6th International Workshop on Ash and Aviation (Citeko, Bogor, Indonesia) discuss volcanic hazards and hazard mitigation strategies while visiting the Gede Volcano.

Kīlauea Volcano's summit vent "then and now." In April 2008, a month after it opened, the vent within Halema‘uma‘u Crater was about 115 feet in diameter (left). As of March 2013, it is more than 500 feet across (right). USGS photos.

The ocean entry near Kupapa`u Point remains active, with no major changes in appearance over the past few weeks. In this view, the two main entry points are visible, with a smaller third entry point (out of view) just beyond these.

Breakouts have been active recently in several locations on the coastal plain. The sluggish flows in this photo were about 1.6 km (1 mile) out from the base of the pali, with a more active patch of breakouts mauka of this location. In addition, several areas of breakouts were active very close to the shoreline and ocean entry.

Structure built by Anasazi and Singuan people north of Sunset Crater, Arizona, in Wupatki National Monument. Agriculture began here because cinder from nearby volcanoes trapped water in soil.

To monitor volcanoes, scientists rely on remote monitoring equipment that can operate 24-hours a day and 365-days a year to deliver real-time data. When scientists design and install monitoring stations, they must consider the remoteness of sites, terrain, and winter conditions. Here, rime ice coats a telemetry system that transmits data near Mount St.

Lava continues to enter the ocean near Kupapa‘u Point, with an entry point just inside the National Park (near left side of photo) and entry points just east of the Park boundary (near the center of the photo). Widely scattered patches of surface lava are also active inland from the ocean entry points.

This is a steep aerial view of the small lava pond at the top of the spatter cone on the northeastern side of the crater floor. Lava in the pond flows directly into a lava tube which is supplying the active flow northeast of Pu‘u ‘Ō‘ō. The head of the tube, marked by fume, extends from the pond toward the left side of the photo.

The "spillway"—Pu‘u ‘Ō‘ō's eastern flank—has been buried by flows fed mostly from a spatter cone on the northeastern side of the crater floor. Most of the dark-colored lava in the foreground is new lava that has resurfaced the spillway. The fume to the left is the trace of the Peace Day tube, newly covered by crater overflows, currently carrying lava to the coast.

This is a view of the front of the Kahauale‘a flow looking back toward Pu‘u ‘Ō‘ō, where the flow originates.

This is another of the spatter cones on the floor of Pu‘u ‘Ō‘ō. This one, on the northeast side of the crater floor, has long had an open top with a view of a small lava lake.

This is a closer look at the spatter cone on the northwest side of Pu‘u ‘Ō‘ō's crater floor. The photo was taken from near the site of the webcam on the north rim of Pu‘u ‘Ō‘ō.
