To better understand the physics of debris flows and to make more accurate hazards forecasts in the natural environment, scientists perform controlled experiments at the large-scale USGS debris flow flume facility.

This photo looks south towards Pu‘u ‘Ō‘ō, where a vent is supplying lava to the Kahauale‘a II flow, north of the cone. This slow-moving flow has reached the forest line, producing small scattered brush fires.

A close-up of the Kahauale‘a II flow burning vegetation at the forest line, just north of Pu‘u ‘Ō‘ō. The flow consists of numerous slow-moving pāhoehoe lobes.

Two ocean entry points remain active near Kupapa‘u Point, near the boundary of Hawai‘i Volcanoes National Park. The eastern entry has produced a larger plume than that at the western entry, which tends to be weak and wispy.

The summit eruption in Halema‘uma‘u crater remains active. The lava lake is within the Overlook crater (the source of the gas plume), which is in the southeast portion of Halema‘uma‘u Crater.

Pagan Volcano is the largest and one of the most active volcanoes in the Northern Mariana Islands. Prior to 2013, the volcano was not monitored with any ground-based instruments, so activity was observed only by satellite or by the few island inhabitants. Although geographically remote, eruptions from Pagan can threaten international air traffic.

Pu‘u ‘Ō‘ō was still close to its maximum height of 255 m (835 ft) in 1992 (top), although its western flank had been partly buried by a lava shield. Since then, the cone has lost a third of its former height due to collapses, and lava has continued to bury its flanks (bottom). USGS photos.

The spatter cone near the north rim of Pu‘u ‘Ō‘ō crater continues to produce pulsating gas jetting sounds. Compare this photo to one taken of the same cone on May 2 to see how much taller the cone has grown.

The small lava lake on the northeast rim of Pu‘u ‘Ō‘ō crater has been built into a small cone, with only a few small openings at the top. One of these small openings had sloshing lava near the surface.
