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.

Why did the lava tube cross the road? This image shows the Peace Day lava tube coming down the pali in Royal Gardens subdivision. The lava tube parallels Ali`i avenue, shown by the straight line of warm temperatures that represent asphalt heated in the sun.

Do not be misguided by the risky actions of this person (upper right), who is standing on an active lava delta that could collapse without warning, amidst a plume of superheated steam, hydrochloric acid, and tiny particles of volcanic glass. To avoid these ocean entry hazards, HVO advises staying at least 400 m (one-quarter mile) from where lava enters the sea.

Methane gas bubbles rise from the seafloor—this type of activity, originally noticed by NOAA Ship Okeanos Explorer in 2012 on a multibeam sonar survey, is what led scientists to the area. Image courtesy of Deepwater Canyons 2013 – Pathways to the Abyss expedition, NOAA-OER/BOEM/USGS.

This image was captured on Monday, May 6, by the Advanced Land Imager sensor aboard NASA's Earth Observing 1 satellite. Although this is a false-color image, the color map has been chosen to mimic what the human eye would expect to see. Bright red pixels depict areas of very high temperatures, and show active or very recently active lava flows.

After a 12 km (7.5 mile) journey from the vent on Pu‘u ‘Ō‘ō cone through a lava tube, lava pours into the ocean in narrow streams at one of the eastern entry points.

Over the past week this spatter cone on the floor of Pu‘u ‘Ō‘ō crater has been the source of several large, but brief, lava flows on the crater floor. Today, the cone was producing pulsating gas jetting sounds.

Another entry point has two larger lava streams entering the water. The lava fragments due to cooling and disruption by the battering surf, and some of these pieces float on the water's surface in front of the entry point (see lower left portion of photo).
